Henry of Almain was the song of one of the wealthiest men in Europe who joined what?
Henry of Almain Henry of Almain (Anglo-Norman French: "Henri d'Almayne") (2 November 1235 – 13 March 1271) was the son of Richard, 1st Earl of Cornwall and his first wife Isabel Marshal. His surname is derived from a vowel shift in pronunciation of "d'Allemagne" (English: of Germany), so called by the elites of England because of his father's status as the elected German King of the Romans (the "King of Almayne").
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.
