The ports had a major role in the Belgrade economy. Belgrade had two ports in the 16th century: a trade port and a military river base anchorage. The trade port was on the north side of the town on the river Danube, while the military one was a bit more to the east. Goods were loaded and unloaded at the trade port in the times of peace, while during the war, the port served for shipping wheat. The wheat was shipped via the Danube from Vlaška, the north part of Bulgaria, and the Smederevo area, while via the Sava from Srem, Mačva and Podrinje.
