Siege of Bursa

Overview

The Siege of Bursa took place from 1317 until the capture of Bursa on 6 April 1326, when the Ottoman Turks deployed a bold plan to seize the city, which was back then known as Prusa. The Ottomans had not captured a city before; the lack of expertise and adequate siege equipment at this stage of the war meant that the city fell only after six or nine years.

Significance

The Siege of Bursa, beginning in 1317 and ending with the Ottoman capture of the city on 6 April 1326, marked a pivotal moment in the Byzantine–Ottoman wars. The fall of Bursa — then known as Prusa — represented the first city the Ottomans had taken, establishing a new threshold for Ottoman military ambition and capability within the conflict. The protracted duration of the siege, lasting six to nine years, reflects the Ottomans' lack of experience and adequate siege equipment at this stage of their expansion. That the city fell despite these limitations underscores the strategic commitment Osman Ghazi, Orhan Ghazi, and Köse Mihal brought to the operation. Bursa's capture gave the Ottoman beylik a substantial urban center and signaled a transformation from a raiding frontier polity into one capable of reducing fortified Byzantine cities, with consequences that would shape the subsequent course of Ottoman expansion in Anatolia.
