Cold War // 1975-1991
Western Sahara War
The Western Sahara War was an armed conflict between the Sahrawi Indigenous Polisario Front and Morocco from 1975 to 1991, being the most significant phase of the Western Sahara conflict. The conflict erupted after the withdrawal of Spain from the Spanish Sahara in accordance with the Madrid Accords, by which it transferred administrative control of the territory to Morocco and Mauritania, but not sovereignty. In late 1975, the Moroccan government organized the Green March of some 350,000 Moroccan citizens, escorted by around 20,000 troops, who entered Western Sahara, trying to establish a Moroccan presence. While at first met with just minor resistance by the Polisario Front, Morocco later engaged a long period of guerrilla warfare with the Sahrawi nationalists. During the late 1970s, the Polisario Front, desiring to establish an independent state in the territory, attempted to fight both Mauritania and Morocco. In 1979, Mauritania withdrew from the conflict after signing a peace treaty with the Polisario Front. The war continued in low intensity throughout the 1980s, though Morocco made several attempts to take the upper hand in 1989–1991. A cease-fire agreement was finally reached between the Polisario Front and Morocco in September 1991. Some sources put the final death toll between 10,000 and 20,000 people.

Causes#
The immediate trigger for the Western Sahara War was Spain's negotiated withdrawal from its colonial territory in late 1975. Under the Madrid Accords, signed in November of that year, Spain transferred administrative control of Spanish Sahara to Morocco and Mauritania without conferring sovereignty — a distinction that left the territory's final status legally unresolved and created the conditions for armed conflict[1]. Within weeks of the accords, Moroccan forces moved to consolidate their position on the ground, and the First Battle of Amgala in early 1976 marked the opening of sustained military operations between Moroccan troops and the Polisario Front.
The structural precondition was Spain's long decline as a colonial power, accelerated by the terminal illness of Francisco Franco and the broader international pressure to decolonize. The United Nations had repeatedly affirmed the right of the Sahrawi people to self-determination through the 1960s and early 1970s, and a 1975 advisory opinion of the International Court of Justice found no legal ties between the territory and Morocco or Mauritania sufficient to override that right[2]. Spain's decision to sidestep a UN-supervised referendum in favor of a bilateral handover effectively foreclosed the decolonization pathway and transferred the conflict from the diplomatic to the military arena[3].
Morocco's claim rested on a combination of historical and nationalist arguments. The Moroccan government invoked the concept of "Greater Morocco," a territorial irredentism that held the Saharan regions to have been part of a pre-colonial Moroccan political sphere[4]. King Hassan II used the issue with considerable domestic effect: the Tan-Tan region had already seen cross-border Sahrawi activity, and popular mobilization around the Saharan question helped consolidate the monarchy's political standing at a moment when it faced internal pressures. The Green March of November 1975 — some 350,000 Moroccan civilians escorted by roughly 20,000 troops — was as much a calculated act of domestic politics as a territorial maneuver[5].
The Polisario Front, founded in 1973, represented the organized expression of Sahrawi nationalism, which had developed partly in reaction to Spanish colonial administration and partly in response to Moroccan and Mauritanian claims on the territory[6]. Polisario drew material and political support from Algeria, whose backing reflected Algiers' own strategic interest in preventing Moroccan territorial expansion along its western flank and its broader commitment to anti-colonial movements on the continent. Algerian support gave Polisario the external base — centered on camps near Tindouf — without which a guerrilla campaign against two state armies would have been impossible to sustain[7].
The geopolitical dimension deepened the conflict's intractability. Morocco was a Western-aligned monarchy whose strategic position on the Atlantic coast of North Africa made it a valued partner for the United States and France, both of which were disinclined to pressure Rabat into concessions. Algeria occupied the opposite alignment in Cold War terms, receiving Soviet arms and offering Polisario a sanctuary that Morocco could not easily destroy. The result was a proxy dimension to the conflict that ensured both parties received sufficient external support to continue fighting well beyond what purely local resources would have sustained, ultimately prolonging the war until the 1991 ceasefire[8].
Consequences#
The ceasefire of September 1991, brokered under United Nations auspices and formalized through [1]'s establishment, ended sixteen years of armed hostilities between Morocco and the [2] without producing a definitive settlement on sovereignty. The UN Mission for the Referendum in Western Sahara was created precisely to organize a vote that would allow the Sahrawi population to choose between independence and integration into Morocco. That referendum has never been held. The mechanism intended to close the conflict instead became the institutional expression of its irresolution, leaving Western Sahara in a legal and political limbo that has persisted for decades [3].
Mauritania's exit from the war in 1979, following its peace agreement with the Polisario Front, produced the most concrete territorial adjustment of the conflict. Mauritania renounced all claims to Tiris al-Gharbiyya, the southern portion of the former Spanish Sahara it had administered since the [4] of 1975. Morocco promptly annexed the vacated territory, effectively absorbing the entire land area Spain had transferred. This expansion was consolidated through Morocco's construction of a sand-and-berm defensive wall — the so-called "berm" — extending some 2,700 kilometers, which by the mid-1980s separated Moroccan-controlled territory from the sparsely populated eastern zones patrolled by Polisario [5]. The berm did not end the war, but it materially altered its character, converting a mobile guerrilla contest into a static frontier, and it remains the de facto boundary today.
The human costs of the conflict generated a displacement crisis whose effects outlasted the fighting. Tens of thousands of Sahrawi civilians fled the territory during and after the Green March and subsequent Moroccan military operations, settling in refugee camps around Tindouf in southwestern Algeria — camps that by the 1980s housed a population estimated in the hundreds of thousands [6]. Algeria's sustained logistical and diplomatic support for the Polisario Front, and Morocco's deepening dependence on French and American political backing, embedded the Western Sahara dispute within broader regional rivalries. The conflict became a principal obstacle to the normalization of Moroccan-Algerian relations and effectively paralyzed the Arab Maghreb Union, the regional integration body founded in 1989, before it could develop meaningful institutional functions [7].
The war did not resolve the foundational question that generated it: the legal status of the territory and the political rights of its indigenous population. The Sahrawi Arab Democratic Republic, proclaimed by the Polisario Front in 1976 and recognized by a substantial number of African and other states, continues to exist as a government in exile based in Tindouf. Morocco's position — that the territory constitutes its "Southern Provinces" and that an autonomy arrangement rather than a referendum on independence is the appropriate outcome — remains irreconcilable with Polisario's demand for self-determination [8]. Successive UN special envoys and negotiating frameworks have failed to bridge this gap. The ceasefire of 1991 thus stands as one of the Cold War era's least resolved endings: a pause in armed hostilities that transformed a military contest into a protracted diplomatic and legal struggle, with the underlying question of sovereignty no closer to resolution than it was when Spanish administration withdrew in 1976.

14 catalogued engagements
- Battles of La Güera and Tichla
December 10, 1975
The Battles of La Güera and Tichla, fought between 10 and 22 December 1975, marked Mauritania's military entry into Western Sahara following the Madrid Accords, under which Spain agreed to partition the territory between Morocco and Mauritania. The Mauritanian Army moved into the southern zone allocated to it, but encountered armed resistance from Polisario Front guerrillas that proved sufficient to require intervention by the Royal Moroccan Army on Mauritania's behalf. Despite this early difficulty, by the close of 1975 Mauritania had established control over the southern half of the former Spanish colony of Río de Oro. The battles established the initial front of a conflict that would pit the two annexing states against the Polisario Front, and Mauritania's early dependence on Moroccan military support foreshadowed the strain the war would place on Nouakchott's limited armed forces throughout the subsequent years of the Western Sahara War.
- Battle of Ain Ben Tili
January 19, 1976
The Battle of Ain Ben Tili demonstrated the Polisario Front's capacity to strike targets inside Mauritanian territory, pressing the war beyond the borders of Western Sahara itself. The attack, which inflicted 150 casualties on Mauritanian forces under Soueidatt Ould Weddad, was significant enough to prompt a Mauritanian withdrawal from the town five days after the engagement. That withdrawal signaled the difficulty Mauritania faced in holding northern border positions against sustained Polisario pressure, foreshadowing the broader strain the war would place on Mauritanian military and political resolve throughout the late 1970s.
- First Battle of Amgala
January 27, 1976
The First Battle of Amgala marked a direct armed clash between Algerian Army units and the Royal Moroccan Armed Forces at the oasis of Amgala, roughly 260 kilometres west of the Algerian border. The engagement drew Algeria into open hostilities with Morocco in the early weeks of the Western Sahara War, transforming what had been proxy and political competition into a confrontation between the two state militaries. After approximately 36 hours of fighting, the Algerian force of around 400 personnel withdrew, sustaining between 106 and 200 casualties. The battle did not end the contest at Amgala: Moroccan and Algerian forces clashed again at the same location within weeks, and in the Second Battle of Amgala in February 1976 Polisario units defeated Moroccan troops, indicating that the first engagement settled little on the ground. The episode sharpened hostility between Rabat and Algiers and underlined Algeria's material stake in the conflict beyond its declared support for the Polisario Front.
- Second Battle of Amgala
February 14, 1976
The Second Battle of Amgala, fought at the Amgala Oasis in February 1976, resulted in the defeat of Moroccan forces stationed there, with the garrison reportedly entirely decimated according to historian Maurice Barbier. The engagement demonstrated the capacity of the Sahrawi People's Liberation Army, the armed wing of the Polisario Front, to strike Moroccan positions with Algerian military support. The battle deepened the direct antagonism between Morocco and Algeria over the Western Sahara conflict, underscoring that the war was not simply an insurgency but a confrontation involving a neighboring state's conventional forces. This alignment between the Polisario Front and Algeria shaped the broader trajectory of the Western Sahara War, hardening the political and military divide that would define the conflict through its duration.
- Attack on Lebouirate
August 24, 1979
The Attack on Lebouirate was a military engagement during the Western Sahara War, the prolonged conflict between Morocco and the Polisario Front, which sought independence for the territory on behalf of the Sahrawi people. The engagement involved Moroccan forces numbering between 600 and 780 personnel and was conducted under Sahrawi Arab Democratic Republic command, with Lahbib Ayoub identified as a commander. Beyond its characterization as a significant engagement in the broader conflict, the specific outcome and its operational effect on the campaign are not recorded.
- Battle of Al Mahbes
October 14, 1979
- Battle of Bir Anzarane
August 11, 1979
The Battle of Bir Anzarane was one of the larger conventional confrontations of the Western Sahara War, pitting Polisario Front forces of the Sahrawi Arab Democratic Republic against the Moroccan Armed Forces at the oasis of Bir Anzarane. The engagement involved several hundred combatants on each side, with casualty figures on both sides indicating a sustained and costly exchange. Within the broader conflict over Western Sahara — a disputed territory claimed by both the SADR and Morocco — engagements of this scale reflected the Polisario Front's capacity to mount significant offensive operations against Moroccan military positions. The battle occurred in August 1979, a period when the Polisario was pressing its guerrilla campaign across the territory following Morocco's annexation of the region after Spanish withdrawal.
- Battle of Tan-Tan
January 28, 1979
The Battle of Tan-Tan marked a significant incursion by Polisario Front forces into Moroccan territory proper, extending the Western Sahara War beyond the disputed territory into southern Morocco. The engagement, involving SADR commanders Lahbib Ayoub and Sidi Ahmed El Batal against Moroccan forces under Abdelaziz Bennani, demonstrated the Polisario Front's capacity to project force across the border and strike at Moroccan soil. The wide disparity in reported force sizes on the SADR side reflects the uncertainty surrounding the engagement, while Moroccan forces numbered approximately 150. No outcome was recorded, leaving the battle's immediate tactical result unclear, though the operation itself signaled the broader reach of the Polisario campaign during this phase of the war.
- Battle of Tichla
July 12, 1979
The Attack on Tichla on July 12, 1979, marked the final engagement between Mauritania and Polisario before the peace treaty signed in Algiers and Mauritania's subsequent withdrawal from the Western Sahara War. With Mauritania sustaining 150 casualties in this action, the battle underscored the mounting costs of Mauritanian involvement in the conflict. The engagement effectively closed Mauritania's participation in the war, removing one of the two state parties aligned against Polisario and altering the strategic balance of the broader Western Sahara conflict.
- Battle of Guelta Zemmur
October 13, 1981
- Battle of Al Mahbes
January 12, 1985
- Battle of Amgala
November 8, 1989
- Battle of Guelta Zemmour
October 7, 1989
- Battle of Hausa
October 10, 1989
The Battle of Haouza occurred on 11 October 1989, when Polisario Front forces attacked the Moroccan Wall in the Haouza region. The engagement came at a diplomatically tense moment: Polisario framed the assault as a direct response to stalled peace negotiations with Morocco and to statements by King Hassan II ruling out further meetings with Sahrawi representatives. Within the broader arc of the Western Sahara War, the attack illustrated how breakdowns in diplomatic contact translated into resumed military pressure along the defensive wall Morocco had constructed across the territory. Recorded casualties of 101 on the RASD side indicate the engagement was a significant operation rather than a minor skirmish, though the outcome is not recorded. The battle reflects the pattern of the conflict's late phase, in which Polisario used offensive action against the wall to signal political resolve when negotiations faltered.

First Indochina War
The First Indochina War, known alternatively internationally as the French Indochina War, was fought in French Indochina between France and the Viet Minh and their respective allies, from 19 December 1946 until 11 August 1954. Most of the engagements of this conflict occurred in Vietnam.
WAR· 1946-1949
Greek Civil War
The Greek Civil War took place from 1946 to 1949. The conflict, which erupted shortly after the end of World War II, consisted of a Communist-led uprising against the established government of the Kingdom of Greece. The rebels declared a people's republic, the Provisional Democratic Government of Greece, which was governed by the Communist Party of Greece (KKE) and its military branch, the Democratic Army of Greece (DSE). The rebels were supported by Albania and Yugoslavia. With the support of the United Kingdom and the United States, the Greek royal government forces ultimately prevailed.
WAR· 1946-1989
Indochina Wars
During the aftermath of World War II and the Cold War, the Indochina wars were a series of wars which were waged in Indochina from 1945 to 1991, by communist forces against the opponents. The term "Indochina" referred to former French Indochina, which included the current states of Vietnam, Laos, and Cambodia. In current usage, it applies largely to a geographic region, rather than to a political area. The wars included:The First Indochina War began after the end of World War II with the War in southern Vietnam (1945–1946), which acted as the precursor to the First Indochina War. The conflict officially began in 1946 as a battle of independence against colonialist powers and lasted until the French defeat in 1954. After a long campaign of unsuccessful resistance against the French and the Japanese, Viet Minh forces claimed a victory in the August Revolution after Japanese forces surrendered to the Allies on 15 August 1945, leading to the fall of the Empire of Vietnam and Nguyễn dynasty. In the War in southern Vietnam (1945–1946), British forces temporarily occupied the South with the objective of disarming Japanese forces, starting from 13 September 1945, only to restore French colonial control in 1946. Meanwhile, the communist Viet Minh sought to consolidate power by terrorizing and purging rival Vietnamese nationalist groups and Trotskyist activists. Additionally, other recently formed groups in Cambodia and Laos, such as the Khmer Issarak and the Lao Issara, also began their own guerrilla movements, advocating for independence in their respective countries. In the United Nations, and through their alliance with the United Kingdom and the United States, the French demanded return of their former Indochina colony prior to agreeing to participate in the NATO alliance opposing Soviet expansion beyond the countries of the Warsaw Pact in the Cold War. With support from China and the Soviet Union, the communist Viet Minh continued fighting the French Union, including the anti-communist State of Vietnam, ultimately forcing the NATO-backed French out of North Vietnam as a result of the 1954 Geneva Conference. The Second Indochina War was a group of interconnected civil wars in Vietnam, Cambodia, and Laos. Most often, it refers to what is called the Vietnam War in the United States. It began as a conflict between the United States-backed South Vietnamese government and its opponents, both the North Vietnamese-based communist Viet Cong and the People's Army of Vietnam (PAVN), known in the West as the North Vietnamese Army (NVA). The conflict began in 1955 and lasted until 1975 when the North Vietnamese army conquered South Vietnam. The United States, which had supported France and its native vassal during the First Indochina war, backed the Republic of Vietnam government in opposition to the communist Viet Cong and PAVN. The North benefited from military and financial support from China, the Soviet Union, and other members of the communist bloc. Fighting also occurred during this time in Cambodia between the US-backed government, the PAVN, and the communist-backed Khmer Rouge, which also fought alongside deposed King Sihanouk's government in exile and in Laos between the US-backed government, the PAVN, and the communist-backed Pathet Lao. The Third Indochina War was a period of prolonged conflict following the Second Indochina War. The conflict began in 1978 and lasted until the 1991 Paris Peace Agreements on 23 October 1991, in which several wars were fought:The Cambodian–Vietnamese War began when Vietnam invaded Cambodia and deposed the genocidal Khmer Rouge regime. The war lasted from 21 December 1978 to 23 October 1991. Cambodia's constitutional monarchy was then restored in 1993.The Sino-Vietnamese War was a four-week war fought in February–March 1979 between the People's Republic of China and the Socialist Republic of Vietnam. The Chinese launched a punitive expedition in revenge for the Vietnamese invasion of Cambodia, and withdrew a month later to prewar positions. Skirmishes along the border would continue until the two countries normalized relations on 5 November 1991.After the triumph of the Pathet Lao, an anti-communist insurgency in Laos lasted until most Hmong insurgents surrendered in 2007, though some resistance cells remained active for several years after. Thailand, which supported the Lao insurgents, as well as the anti-Vietnamese forces in the Third Indochina War, fought a few skirmishes with Vietnam in 1984, and a short conflict with Laos in 1987.FULRO insurgency in Vietnam – United Front for the Liberation of Oppressed RacesThe Communist Party of Thailand fought an insurgency from 1965 to 1989. They received backing from Laos and Vietnam from 1975 to 1979 but were expelled from their bases and lost most of their supply lines after they sided with the Cambodian-Chinese aligned forces, rather than the pro-Soviet Vietnamese and Laotian regimes.
WAR· 1947-1948
1947–1948 Civil War in Mandatory Palestine
The 1947–1948 civil war in Mandatory Palestine was the first phase of the 1948 Palestine war. It broke out after the General Assembly of the United Nations adopted a resolution on 29 November 1947 recommending the adoption of the Partition Plan for Palestine.
