Orhan, Bursa, and the Crossing into Europe
On the timeline · around 1326–1354 CE ·
What happened
Osman's son Orhan captured Bursa in 1326 and made it the Ottoman capital, then seized Byzantine cities across Anatolia. By 1354 the Ottomans had crossed the Dardanelles at Gallipoli, gaining their first foothold in Europe.
Why it matters
The leap into Europe transformed a regional beylik into a power poised to swallow the Balkans and, one day, Constantinople itself.
