Siege of Belgrade (1440)

Siege · 1440

After taking Smederevo, Murad II also sought to take the fortress of Belgrade, the strongest point of the Serbian inheritance still in Hungarian hands. According to the TDV encyclopedia, the siege begun in 1440 lasted six months without result; musket fire, used against the Turks for the first time, seems to have been one of the reasons for the failure. The same year Şehabeddin Şahin Pasha, governor-general of Rumelia, took Novo Brdo with its silver mines. The failure at Belgrade was a turning point for Murad II.

Context of the period

By the atlas's calculation the Ottoman lands covered about 677,000 km² in 1440; at the start of Murad II's reign they measured 593,000 km², at its end 664,000 km².

During Murad II (1421–1444) the atlas records 4 regions gained and 1 region lost.

Regions gained: Teke–Hamid (Antalya–Isparta–Burdur) (1423), Germiyan (Kütahya–Afyon–Uşak) (1429), Thessaloniki–Chalkidiki–Mount Athos (1430), Ioannina (Epirus) (1430).

Regions lost: Northern Albania (Krujë–Shkodër) (1443).

Murad II in brief

He restored Ottoman rule after the Interregnum: Thessalonica was taken, Germiyan joined and the Eastern Roman Empire (Byzantium) again paid tribute. In 1444, after the peace of Edirne–Szeged, he abdicated and withdrew to Manisa; recalled to lead the army at Varna, he returned to the throne in 1446.
