Andronikos II Palaiologos (; 25 March 1259 – 13 February 1332), Latinized as Andronicus II Palaeologus, reigned as Byzantine emperor from 1282 to 1328. His reign marked the beginning of the recently-restored empire's final decline. The Turks conquered most of Byzantium's remaining Anatolian territories, and Andronikos spent the last years of his reign fighting his own grandson in the First Palaiologan Civil War. The war ended in Andronikos' forced abdication in 1328, after which he retired to a monastery for the remainder of his life.
Life
Andronikos was born on 25 March 1259, at Nicaea. He was the eldest surviving son of Michael VIII Palaiologos and Theodora Palaiologina, grandniece of John III Doukas Vatatzes.
Andronikos was acclaimed co-emperor in 1261, after his father Michael VIII recovered Constantinople from the Latin Empire, but he was not crowned until 8 November 1272. During their joint rule, he was compelled to support his father's unpopular Church union with the Papacy. Made sole emperor by Michael's death in 1282, Andronikos immediately repudiated the union, but was unable to resolve the related schism within the Orthodox clergy until 1310.
Andronikos II was also plagued by economic difficulties. During his reign the value of the Byzantine hyperpyron depreciated precipitously, while the state treasury accumulated less than one seventh the revenue (in nominal coins) that it had previously. Seeking to increase revenue and reduce expenses, Andronikos II raised taxes, reduced tax exemptions, and dismantled the Byzantine fleet (80 ships) in 1285, thereby making the Empire increasingly dependent on the rival republics of Venice and Genoa.
In 1291, he hired 50–60 Genoese ships, but the Byzantine weakness resulting from the lack of a navy became painfully apparent in the two wars with Venice in 1296–1302, and later again in 1306–10. In 1320, he tried to resurrect the navy by constructing 20 galleys, but failed.
Andronikos II Palaiologos sought to resolve some of the problems facing the Byzantine Empire through diplomacy. After the death of his first wife, Anne of Hungary, he married Yolanda (renamed Irene) of Montferrat, putting an end to the Montferrat claim to the Kingdom of Thessalonica.
Andronikos II also attempted to marry off his son and co-emperor Michael IX Palaiologos to the Latin Empress Catherine I of Courtenay, thus seeking to eliminate Western agitation for a restoration of the Latin Empire. Another marriage alliance attempted to resolve the potential conflict with Serbia in Macedonia, as Andronikos II married off his five-year-old daughter Simonis to King Stefan Milutin in 1298.
In spite of the resolution of problems in Europe, Andronikos II was faced with the collapse of the Byzantine frontier in Asia Minor, despite the successful, but short, governorships of Alexios Philanthropenos and John Tarchaneiotes. The military victories of Philanthropenos and Tarchaneiotes against the Turks were largely dependent on a considerable contingent of Cretan escapees, or exiles from Venetian-occupied Crete, headed by Hortatzis, whom Michael VIII had repatriated to Byzantium through a treaty agreement with the Venetians ratified in 1277. Andronikos II had resettled those Cretans in the region of Meander river, the southeastern Asia Minor frontier of Byzantium with the Turks.
After the failure of the co-emperor Michael IX to stem the Turkish advance in Asia Minor in 1302 and the disastrous Battle of Bapheus, the Byzantine government hired the Catalan Company of Almogavars (adventurers from Catalonia) led by Roger de Flor to clear Byzantine Asia Minor of the enemy. In spite of some successes, the Catalans were unable to secure lasting gains. Being more ruthless and savage than the enemy they intended to subdue, they quarreled with Michael IX and eventually turned on their Byzantine employers after the murder of Roger de Flor in 1305. Together with a party of willing Turks they devastated Thrace, Macedonia, and Thessaly on their road to Latin occupied southern Greece. There they conquered the Duchy of Athens and Thebes.
Meanwhile, the Anatolian beyliks continued to penetrate Byzantine territory. Prusa fell to the Ottoman Turks in 1326, and by the end of Andronikos II's reign much of Bithynia was in the hands of Osman I and his son and heir Orhan. Karasids conquered Mysia-region with Paleokastron after 1296, Germiyan conquered Simav in 1328, Saruhan captured Magnesia in 1313, and Aydinids captured Smyrna in 1310.
