John I (Breton:Yann,French:Jean;c. 1217/1218 – 8 October 1286), known asJohn the Red due to the colour of his beard, wasDuke of Brittany from 1221 to his death and 2ndEarl of Richmond in 1268.
John was the eldest of three children born toDuchess Alix and herhusband and co-ruler,Duke Peter I.[1] He became duke upon his mother's death in 1221. His father, who had reigned as duke due to his marriage to Alix, ruled as regent until John reached adulthood.[2] In 1268, Henry III granted the earldom of Richmond to John,[3] and the title continued in his family, through frequent temporary forfeitures and reversions, until 1342.
He experienced a number of conflicts with theBishop of Nantes and the Breton clergy. In 1240, he issued an edict expelling Jews from the duchy and cancelling all debts to them.[4] He joinedLouis IX of France in theEighth Crusade in 1270, and survived the plague that killed the king. The duchy of Brittany experienced a century of peace, beginning with John I and ending withDuke John III's reign in 1341.[5]
In 1236 John married InfantaBlanche, daughter of KingTheobald I of Navarre.[6] They had the following surviving issue:
