Baja California Territory

Baja California Territory (Territorio de Baja California) was a federal territory of Mexico that existed from 1824 to 1853, and 1854 to 1931; it encompassed the Baja California peninsula of present-day northwestern part of the country. It replaced the Baja California Province (1773–1824) of the Spanish colonial Viceroyalty of New Spain, after Mexican independence. Along with Alta California, the two territories were split from the Spanish Californias region.

In 1931, Baja California Territory was divided into the "Territory of Baja California Norte" and the "Territory of Baja California Sur". In 1952, the "North Territory" became the 29th State of Mexico as Baja California. In 1974, the "South Territory" became the 31st state as Baja California Sur.
