Life journey

1. Siege of Kulaca Hisar1285 CE
   The Siege of Kulaca Hisar was a battle fought between the Byzantines and the Turks under the command of Osman Gazi in 1285 for control of Fort Kulaca.
2. Siege of İnegöl1299 CE
   The Siege of İnegöl took place between Agios Nikolaos, the governor of the fort, and the Kayı army under the command of Turgut Alp. This conquest was one of the first conquests in Ottoman history after the siege of Kulaca Hisar. After the end of the siege, Tekfur Nikolaos was executed by Turgut Alp. The conquest took place in 1299. This battle triggered the Battle of Bapheus, where the Byzantines attempted to reconquer the lost territory, which in turn led to the Siege of Bursa eventually leading to the establishment of the Ottoman Beylik.
3. Battle of Bapheus1302 CE
   The Battle of Bapheus occurred on 27 July 1302, between an Ottoman army under Osman I and a Byzantine army under George Mouzalon. The battle ended in a crucial Ottoman victory, cementing the Ottoman state and heralding the final capture of Byzantine Bithynia by the Ottoman Turks.
4. Siege of Bursa1317 CE
   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.
