Latin Emperor of Constantinople (1216–1217) who was crowned in Rome but captured by the Greeks of Epirus on his way east, dying in prison without ever reaching his capital.
Peter of Courtenay was, in title, Latin Emperor of Constantinople from 1216 to 1217, though he never once set foot in the city he was chosen to rule. A French prince of the house of Courtenay and a cousin of the king of France, he was elected to the throne of the Latin Empire — the crusader state set up in Constantinople after the Fourth Crusade — through his marriage to Yolanda, sister of the first two Latin emperors.
Crowned by the pope in Rome in 1217, Peter set out overland to claim his empire, but was ambushed and captured by Theodore Komnenos Doukas, the Greek ruler of Epirus, and died a prisoner. His empire was governed in his absence by his wife Yolanda and then passed to their sons.
Peter was born about 1155 into the house of Courtenay, a cadet branch of the French royal family; his father was a son of King Louis VI. As count of Nevers, Auxerre, and Tonnerre, and a cousin of King Philip II of France, he was a considerable French magnate who had taken part in crusading ventures in the West.
His link to the throne of Constantinople came through his second wife, Yolanda of Flanders, the sister of Baldwin I and Henry of Flanders, the first two Latin emperors. When Henry died in 1216 leaving no son, the barons of the Latin Empire offered the crown to Peter as Yolanda's husband.
Peter of Courtenay is a figure known more for his misfortune than his character; his reign was so brief and so entirely spent in transit and captivity that little of the man himself emerges. He appears as a substantial but not especially distinguished French prince, whose chief qualification for an imperial throne was his marriage and his royal blood rather than any great ability or ambition of his own.
What his short, disastrous reign illustrates is the fragility and over-extension of the Latin Empire itself — a crusader state so weak that its chosen emperor could be waylaid and imprisoned by a regional Greek lord before he ever reached his capital. Peter was, in effect, the victim of a hopeless inheritance: a crown that carried grand titles but could no longer guarantee even the safe passage of the man who wore it.
Accepting the crown, Peter travelled to Rome, where in 1217 Pope Honorius III crowned him emperor — though pointedly in a church outside the walls, so as not to imply any imperial claim over Rome itself. His wife Yolanda went ahead by sea to Constantinople, where she took up the regency and where their son Baldwin was born.
Peter, meanwhile, agreed to help the Venetians recover the port of Durazzo on his way east, then struck out overland across the Balkans toward his capital. In the mountains of Epirus he was ambushed and taken prisoner by Theodore Komnenos Doukas, the ambitious Greek ruler of Epirus, and vanished into captivity. He never reached Constantinople and died a prisoner, probably in 1219.
Peter died in captivity in Epirus around 1219. His wife Yolanda had already been governing the empire as regent from Constantinople; on her own death the throne passed in turn to their sons Robert and, later, Baldwin II, the last Latin emperor.
Peter of Courtenay is remembered as the Latin emperor who never reigned — a striking emblem of the weakness of the crusader empire of Constantinople, whose sovereign could be seized and imprisoned by a Greek provincial ruler before ever seeing his throne. His capture underlined the rising power of the Greek successor states, above all Epirus and Nicaea, that would hem in and ultimately overthrow the Latin Empire, restoring Byzantine rule to Constantinople in 1261.
