[SEP] Knowledge 2: Henry I of France
Henry I (4 May 1008 – 4 August 1060) was King of the Franks from 1031 to 1060.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.
