尼西亚帝国
Michael VIII Palaiologos or Palaeologus (; 1223 – 11 December 1282) reigned as the co-emperor of the Empire of Nicaea from 1259 to 1261, and as Byzantine Emperor from 1261 until his death. Michael VIII was the founder of the Palaiologan dynasty that would rule the Byzantine Empire until the Fall of Constantinople in 1453. He recovered Constantinople from the Latin Empire in 1261 and transformed the Empire of Nicaea into a restored Byzantine Empire.
