The Count of Portugal was a title held by the rulers of the County of Portugal, which emerged in the 12th century. This region was part of the larger Kingdom of León before gaining autonomy. The title was established when the county was granted to Henry of Portugal, a nobleman, in 1096. In 1139, the title evolved when Afonso I declared himself King of Portugal, marking the transition from a countship to a kingdom. The Count of Portugal played a crucial role in the early formation of the Portuguese state and its identity, laying the groundwork for future governance.
