Philip of Cognac

Philip of Cognac (early 1180s – after 1211^[1]) was an illegitimate son of King Richard I of England,^[2] by an unidentified mother.

Philip had reached adulthood by the end of the 1190s. His father married him to his ward, Amelia, the heiress of Cognac, France, in Charente. However, when she died without issue, Richard kept the castle, and handed it over to his seneschal, Robert of Thornham.^[3]

The king was mortally wounded during the suppression of a revolt by Viscount Aimar V of Limoges in 1199, and died without legitimate heirs. The chronicler Roger of Howden claimed that later that same year,

Philip, illegitimate son of King Richard of England, to whom the aforesaid king his father had granted the castle and honour of Cognac, slew the previously mentioned Viscount of Limoges in vengeance for his father."^[4]

No other source corroborates this, or explicitly indicates that Aimar of Limoges's death was a violent one. However, Guiraut de Bornelh's planh (lament) for him, Planc e sospir, does suggest his death was unexpected.

A further reference to Philip is found in the pipe rolls for 1201 of his uncle, John, King of England: "Et Philippo f. R. Ricardi L m. de dono R." ("And to Philip, son of King Richard, fifty marks as a gift"), but little is known afterwards.^[5]
