wikipediaJohn VII Palaiologos or Palaeologus (Greek: Ιωάννης Ζ' Παλαιολόγος, Iōannēs Z' Palaiologos; 1370 – 22 September 1408) was Byzantine Emperor for five months in 1390. While he was Emperor, there is evidence showing he used the name Andronikos, after his father, although when he was regent during his uncle's absence in the West, he governed in his birth name.[1]
