The province was founded in 1579 (?) and was split into two, Camarines Norte and Sur in 1829. They were reunited under Ambos Camarines in 1854, but split again after three years. In 1893, they were reunited until March 10, 1917, when Philippine Republic Act 2711 formed most of the present-day provinces, including Camarines Norte and Camarines Sur.
