Henry of Almain was the song of one of the wealthiest men in Europe who joined what?
Richard, 1st Earl of Cornwall Richard (5 January 1209 – 2 April 1272), second son of John, King of England, was the nominal Count of Poitou (1225-1243), Earl of Cornwall (from 1225) and King of Germany (from 1257). He was one of the wealthiest men in Europe and joined the Barons' Crusade, where he achieved success as a negotiator for the release of prisoners and assisted with the building of the citadel in Ascalon.
Henry I of France Henry I (4 May 1008 – 4 August 1060) was King of the Franks from 1031 to his death. The royal demesne of France reached its smallest size during his reign, and for this reason he is often seen as emblematic of the weakness of the early Capetians. This is not entirely agreed upon, however, as other historians regard him as a strong but realistic king, who was forced to conduct a policy mindful of the limitations of the French monarchy.
