Commemorations regarding the early Ottoman Empire and the conquest of Bursa have highlighted various historical sites and academic perspectives. Initial focus was placed on the historical route leading to the conquest, which spans the Bilecik, Söğüt, Yenişehir, and İnegöl regions. Key landmarks along this corridor include the Tomb of Ertuğrul Gazi in Söğüt, the Kuyulu Mosque, and the Tomb of Sheikh Edebali in Bilecik.

As part of the 700th anniversary of the conquest of Bursa, the Bursa Metropolitan Municipality organized a symposium titled ‘Bursa, the Capital of Foundation’. Academic discussions at the event emphasized Bursa’s role as the last major Byzantine city in Anatolia and its significance as a foundation point for the Ottoman state, drawing comparisons to the importance of Konya for the Seljuks.
