Ottoman State under Murad I

Timeline

1. 1362–1364Bursa · AnatoliaAfter succeeding his father Orhan, Murad I consolidated territory in northwestern Anatolia, suppressed internal bey rebellions, and reorganized the court and military command systems, laying an administrative foundation for expansion into Europe.
2. 1361–1365Edirne · ThraceAfter capturing Edirne, the Ottomans moved the capital to the European side, shifting the state's center from an Anatolian beylik to a straddling-the-straits empire; Thrace's local administration, taxation, and garrison systems were established, greatly weakening Byzantium's Balkan bulwark.
3. 1360–1370Thrace and northwestern Anatolia · Early Ottoman territoriesUnder Murad I the timar fief system became regularized, with cavalry lords exchanging land revenue for military service; captives and the devshirme levy supplemented palace slaves and infantry, and the Janissary corps began to take shape in the late 1360s, establishing the skeleton of the Ottoman military state.
