Smederevo (Serbian Cyrillic: Смедерево, pronounced [smêdereʋo] ⓘ) is a city and the administrative center of the Podunavlje District in eastern Serbia.

Its history starts in the 1st century BC, after the conquest of the Roman Empire, when there existed a settlement by the name of Vinceia.

The modern city traces its roots back to the Late Middle Ages when it was the capital (1430–39, and 1444–59) of the last independent Serbian state before Ottoman conquest.

In Serbian, the city is known as Smederevo (Смедерево), in Latin, Italian, Romanian and Greek as Semendria, in Hungarian as Szendrő or Vég-Szendrő, and in Turkish as Semendire.

The name of Smederevo was first recorded in the Charter of the Byzantine Emperor Basil II from 1019, in the part related to the Eparchy of Braničevo (a suffragan diocese of the Archdiocese of Ochrid).

Another written record is found in the Charter of Duke Lazar of Serbia from 1381, by which he bestowed the Monastery of Ravanica and villages and properties 'to the Great Bogosav with the commune and heritage'’.

Vinceia held significance as a principal town of Moesia Superior, situated near the confluence of the Margus and Brongus rivers.

[7] According to the Greek historian Theodore Spandounes, the fortress was constructed by George Kantakouzenos, Branković's brother-in-law through his consort the Byzantine princess Irene.

[8] Smederevo was the residence of the Branković house and the capital of the Serbian Despotate from 1430 until 1439, when it was conquered by the Ottoman Empire after a siege lasting two months.

In 1444, in accordance with the terms of the Peace of Szeged between the Kingdom of Hungary and the Ottoman Empire, the Sultan returned Smederevo to Đurađ Branković, who was allied to the Hungarian commander John Hunyadi.

Serbia became a battleground between the Kingdom of Hungary and the Ottomans, and the angry Branković captured Hunyadi after his defeat at the Second Battle of Kosovo in 1448.

The city is home to the only operating steel mill in the country, Železara Smederevo, previously known as Sartid, which is situated in the suburb of Radinac.

[15] In 2016, the Serbian government managed to strike a deal with a Chinese conglomerate Hesteel Group, which purchased the effective assets for $46 million.

[17] However, the consortium lost its permit to build the refinery after it failed to meet payment deadlines for the land lease a year later.
