Who was John IV Laskaris?

John IV Doukas Laskaris was the last emperor of the Laskarid dynasty of the Empire of Nicaea, born to Emperor Theodore II Doukas Laskaris and Elena of Bulgaria. His rule began tragically young, at seven, upon his father’s death. His maternal grandparents included notable figures such as Ivan Asen II of Bulgaria and Anna Maria of Hungary, linking him to a broad European heritage.

Initially, John IV’s regency was managed by the bureaucrat George Mouzalon, but following Mouzalon’s assassination orchestrated by the nobility, Michael VIII Palaiologos, a distant relative and ambitious noble, seized control.

By January 1, 1259, Michael had declared himself co-emperor, and following his successful recapture of Constantinople from the Latin Empire in July 1261, he effectively sidelined John IV. On his eleventh birthday in December 1261, John IV was tragically blinded on Michael’s orders—a brutal act that rendered him ineligible for the throne and led to his exile in a Bithynian fortress. This cruel fate provoked the excommunication of Michael VIII by Patriarch Arsenius Autoreianus and fueled further revolts.

John IV lived out his days as a monk in Dacibyza, despite rumors spurred by Charles of Anjou in 1273 that he had escaped and was welcome at the Angevin court—a political maneuver likely intended to garner support among the Greeks under Angevin rule. Historical records from Pachymeres and Gregoras, however, indicate that John IV remained in Dacibyza well beyond Michael’s death, suggesting that Charles’s claims were primarily propagandistic.

In a poignant moment of historical reconciliation, Michael VIII’s son, Andronikos II Palaiologos, visited John IV in 1290, seeking forgiveness for the sins of his father. This visit, though fraught with discomfort, highlights the complex interplay of personal and political motives in Byzantine imperial actions. John IV’s death around 1305 marked the end of his tormented life, but he was later venerated as a saint, reflecting a posthumous rehabilitation of his legacy within Byzantine collective memory.
