Nicephorus Gregoras was a Byzantine Greek astronomer, historian, and theologian. His 37-volume Byzantine History, a work of erudition, constitutes a primary documentary source for the 14th century.
Nikephoros Gregoras
Andronikos III Palaiologos
Andronikos III Palaiologos, commonly Latinized as Andronicus III Palaeologus, was the Byzantine emperor from 1328 to 1341. He was the son of Michael IX Palaiologos and Rita of Armenia. He was proclaimed co-emperor in his youth, before 1313, and in April 1321 he rebelled against his grandfather, Andronikos II Palaiologos. He was formally crowned co-emperor in February 1325, before ousting his grandfather outright and becoming sole emperor on 24 May 1328.
