Henry IV married Joan, sister of King Alfonso V of Portugal in 1455 as his second wife and in 1462 she gave birth to Joanna, "the Infanta," mentioned in this letter. At the time of Joanna's birth, Henry was rumored to be impotent and most of his subjects believed that "the Infanta" was not Henry's heir, but the daughter of a Castilian noble with whom his queen was having an affair. When civil war broke out over the question of a legitimate succession, Henry sought assistance from his loyal nobles, including the Count of Arcos, an Andulusian nobleman who had been a member of his father's council. This letter, signed by Henry as "I the King," [the ancient customary formal signature of Spanish monarchs], was written as the king sought support within his kingdom and gave the count "leave to continue acting in his behalf." Less than a month later Henry IV was deposed in favor of the king's 11-year-old half brother, King Alfonso XII and when Alfonso died in 1468 his sister, Isabella, became the recognized heir but refused the throne while Henry was still alive, thus ending the civil war. When Henry finally died in 1474, Joanna's claim to the throne was dismissed because of her questionable parentage and Isabella, her aunt, became queen. However, Joanna always believed she was the rightful Queen of Spain. that she should have succeeded Henry IV, and took to signing her letters “Yo la Reyna” (“I the Queen”). RRAuction COA.
