The [[Palaiologan Byzantine army|Palaiologan army]] refers to the military forces of the [[Byzantine Empire]] from the late 13th century to its final collapse in the mid 15th century, under the [[Palaiologos|House of the Palaiologoi]]. The army was a direct continuation of the forces of the Nicaean army, which itself was a fractured component of the formidable [[Komnenian army]]. Under the first Palaiologan emperor, Michael VIII, the army's role took an increasingly offensive role whilst the naval forces of the Empire, weakened since the days of Andronikos I Komnenos, were boosted to include thousands of skilled sailors and some 80 ships. Due to the lack of land to support the army, the Empire required the use of large numbers of mercenaries.

After Andronikos II took to the throne, the army fell apart and the Byzantines suffered regular defeats at the hands of their eastern opponents, although they would continue to enjoy success against the crusader territories in Greece. By c. 1350, following a [[Byzantine civil war of 1341–1347|destructive civil war]] and the outbreak of the [[Black Death]], the Empire was no longer capable of raising troops and the supplies to maintain them. The Empire came to rely upon troops provided by Serbs, Bulgarians, Venetians, Latins, Genoans and Ottoman Turks to fight the civil wars that lasted for the greater part of the 14th century, with the latter foe being the most successful in establishing a foothold in Thrace. The Ottomans swiftly expanded through the Balkans and cut off Constantinople, the capital of the Byzantine Empire, from the surrounding land. The last decisive battle was fought by the Palaiologan army in 1453, when Constantinople was besieged and [[Fall of Constantinople|fell]] on 29 May. The last isolated remnants of the Byzantine state were conquered by 1461.
