Andronikos V Palaiologos was born 1400. The only son of
John VII Palaiologos ( 1390, 1403–1408) and his wife
Irene Gattilusio, Andronikos was named after his paternal grandfather,
Andronikos IV Palaiologos ( 1376–1379). John VII had briefly ruled the Byzantine Empire in 1390, after usurping the throne from his grandfather,
John V Palaiologos ( 1341–1391). Although John VII had been deposed after just five months on the throne, he never gave up his claim to be the legitimate senior emperor, even after the accession of John V's successor,
Manuel II Palaiologos ( 1391–1425), John VII's uncle, in 1391. After a long feud between the two, and risking civil war, Manuel and John VII reached an agreement in 1403, in which John VII, still officially a junior emperor, would reign alone after Manuel's death. Per the agreement, John VII would then be succeeded by Manuel's son,
John VIII Palaiologos ( 1425–1448), who in turn would be succeeded by John VII's son, Andronikos V. Additionally, John VII was granted the city of
Thessalonica, whom he had recently been responsible for returning to Byzantine control, and was also allowed to keep the title of emperor. Shortly after arriving in Thessalonica in 1403, John VII established his own imperial court there and crowned Andronikos V as co-emperor. The emperors in Thessalonica continued to use the full imperial title, which they were entitled to per the agreement with Manuel, employing both the styles
basileus (emperor) and
autokrator (autocrat). John VII regarded Andronikos V not just as his own successor, but also the future legitimate senior Byzantine emperor. John VII's entry into Thessalonica was commemorated in a Byzantine ivory
pyxis (a cylindrical box with a lid), today housed at
Dumbarton Oaks, which depicts the families of both John VII and Manuel. The pyxis notably depicts Andronikos V more prominently than Manuel's son John VIII, despite John VIII being both older and higher in the line of succession. The plans and hopes for Andronikos V's future fell through when he died 1407, at the age of seven.
Monodies (lamentations for a death) were composed for Andronikos and John VII succumbed to intense grief. The
Metropolitan of Thessalonica,
Gabriel I, wrote a consolatory letter to John VII. In his letter, Gabriel wrote that he too grieved, since he had prayed that the young emperor would grow to adulthood and succeed his father and also stated that he regretted not being present in Thessalonica at the time to offer consolation and sympathy in person. John VII died not long after Andronikos, on 22 September 1408, ending the Byzantine
diarchy established in 1403 and John VII's rival imperial lineage. == Historiography ==
