Beginning in 1939, several political groups that promoted the conversion of the Baja territory into a state of
Mexico were created. On 15 November 1951,
President Miguel Alemán Valdés sent Congress a proposed
amendment to Articles 43 and 45 of the constitution to transform the Territory of Baja California Norte into the
Free and Sovereign State of Baja California. The decree was approved on 31 December 1951 and was published in the
Official Journal of the Federation on 16 January 1952. The last
territorial governor,
Alfonso García González, was appointed provisional
governor of the newly created state. ==References==
