レオン王国
The Kingdom of León coexisted as a personal union under the Crown of Castile, with León possessing separate institutions, such as its own "cortes", the "Real Adelantamiento" of the Kingdom of León, and the "Merino mayor" of León, among others, many of which lasted until the 19th century. The Castilian monarchs, however, soon began a process of unifying the laws of the two kingdoms, as exemplified by the Siete Partidas. By the 16th century, León became a captaincy-general.
