Recognized as [[heir presumptive]] during his brother's reign, Henry succeeded to the thrones of the [[Kingdom of Navarre]] and [[County of Champagne]] upon Theobald II's death in December 1270. Henry I's proclamation at [[Pamplona]], however, did not take place until the following year, 1 March 1271,{{sfn|Procter|1980|p=255}} and his coronation was delayed until May 1273. His first act was the swear to uphold the [[Fueros of Navarre]] and then go to perform [[Homage (feudal)|homage]] to [[Philip III of France]] for Champagne.

Henry came to the throne at the height of an economic boom in Navarre that was not happening elsewhere in Iberia at as great a rate. But by the [[Treaty of Paris (1259)]], the [[Kingdom of England|English]] had been ceded rights in [[Gascony]] that effectively cut off Navarrese access to the ocean (since France, Navarre's ally, was at odds with England). Henry allowed the Pamplonese burg of Navarrería to disentangle itself from the union of San Cernin and San Nicolás, effected in 1266. He also granted privileges to the towns of [[Estella-Lizarra|Estella]], [[Los Arcos]], and [[Viana, Spain|Viana]], fostering urban growth. His relations with the nobility were, on the whole, friendly, though he was prepared to maintain the peace of his realm at nearly any cost.

Henry initially sought to recover territory lost to [[Kingdom of Castile|Castile]] by assisting the revolt of King [[Alfonso X of Castile]]'s brother [[Philip of Castile (died 1274)|Philip]] in 1270. He eventually declined, preferring to establish an alliance with Castile through the marriage of his son Theobald to Alfonso X's daughter [[Violant of Castile|Violant]] in September 1272.{{sfn|Kinkade|1992|p=294}} This failed with the death of the young Theobald after he fell from a [[battlement]] at the [[castle]] of Estella in 1273.{{sfn|Woodacre|2013|p=25}}
