By place

Byzantine Empire

Summer – Emperor Michael VIII (Palaiologos) sends a Byzantine expeditionary force (some 3,500 men) led by his half-brother, Constantine Palaiologos, to the Peloponnese in southern Greece. The army is transported to Monemvasia on Genoese ships, while a small Byzantine fleet is sent to harass the Latin island holdings in Euboea and the Cyclades. After arriving at Monemvasia, Constantine lays siege to Lacedaemon (or Sparta), while the Byzantine fleet seizes the southern coast of Laconia. Battle of Prinitza: Constantine Palaiologos marches the Byzantine army up the rivers Eurotas and Alfeios towards the Achaean capital, Andravida. At a narrow pass at Prinitza (near Ancient Olympia) in Elis, the Byzantines are attacked by Achaean forces (some 300 horsemen) under John of Katavas, who inflict a resounding defeat upon them; many Byzantine soldiers are killed. Constantine himself barely escapes with his life, and flees with the remainder of his army to the safety of Mystras.Longnon, Jean (1969). The Frankish States in Greece, 1204–1311, pp. 253–254.

Battle of Settepozzi: A Byzantine-Genoese fleet (some 50 galleys) is routed by the Venetians near Spetses in the Argolic Gulf, who capture four ships and inflict considerable casualties. Later, the Genoese that survive the battle managed to capture Chania on Crete. They receive orders to avoid direct confrontations with the Venetian fleet, but instead are engaged in raiding against the Venetian merchant convoys in the Euripus Strait.

Europe

July – Scottish–Norwegian War: King Haakon IV (the Old) assembles a fleet (some 120 warships), and sets sail to defend the Hebrides, in an attempt to reassert Norwegian sovereignty over the Western Isles of Scotland. Haakon stops at the Isle of Arran – where in August negotiations are started with the 21-year-old King Alexander III. The talks are prolonged by the Scots until the autumn storms begin. October 2 – Battle of Largs: Scottish forces under Alexander Stewart rout a Viking invasion force led by Haakon IV at Largs in North Ayrshire. The battle is inconclusive, on the morning of October 3, the Norwegians return to collect their dead and burn their beached ships. By the end of October, the Viking fleet reaches Orkney, where Haakon becomes ill and dies at the Bishop's Palace, on December 16. December – Magnus VI (the Law-mender) succeeds his father Haakon IV (the Old) as king of Norway. The chieftains of the eastern part of Iceland become the last to pledge fealty to Magnus – bringing a more complete end to the Icelandic Commonwealth and the Age of the Sturlungs. Mindaugas (Mendog), the only Christian king of Lithuania, is assassinated by his cousin Treniota. The country reverts to paganism and loses its status as a kingdom. Treniota usurps the throne (until 1264). King James I (the Conqueror) captures Crevillent from the Moors and becomes a part of the Kingdom of Valencia during the Reconquista. Winter – King Alfonso X (the Wise) conquers Niebla from the Moors – terminating any Muslim presence in the western region of Spain.
