French Cameroon became independent in 1960 as the Republic of Cameroon. The following year the southern portion of neighboring British Cameroon voted to merge with the new country to form the Federal Republic of Cameroon. In 1972, a new constitution replaced the federation with a unitaryunitary state, the United Republic of Cameroon. The country has generally enjoyed stability, which has enabled the development of agriculture, roads, and railways, as well as a petroleum industry. Despite slow movement toward democratic reform, political power remains firmly in the hands of President Paul BIYA.
