description: "He reigned over Byzantium for half a century and watched it collapse in slow motion. John V Palaiologos held the throne longer than almost any Byzantine emperor — through plague, civil wars with his own family, and the steady advance of the Ottomans who turned his empire into a client state."

# bio (long form, separated for readability)
bio: |
  John V became emperor at eight in 1332, triggering a civil war between his mother Anna of Savoy — who pawned the crown jewels to Venice for cash — and his regent John VI Kantakouzenos. Kantakouzenos claimed the throne in 1347, the same year the Black Death arrived. Another civil war erupted in 1352 when John V enlisted Serbian help against Kantakouzenos's son; the Ottomans used the chaos to seize their first foothold in Europe. John V took real power in 1354, then spent years begging the West for aid, converting to Catholicism before the Pope in 1369 in a failed bid for support. Venice imprisoned him for debt; the Ottomans forced him to accept vassal status. His own son Andronikos IV overthrew him in 1376, then his grandson John VII did it again in 1390. He died in February 1391, outlasting the empire he couldn't save.
