Lesotho, is a country in Southern Africa. Entirely surrounded by South Africa, it is the largest of only three sovereign enclaves in the world, the others being San Marino and Vatican City, which are surrounded by Italy. Lesotho is situated in the Maloti Mountains and contains the highest peak in Southern Africa. It has an area of over 30,000 km2 (11,600 sq mi) and has a population of about 2.311 million. Its capital and largest city is Maseru. Lesotho was formed in 1824 by King Moshoeshoe I. Continuous encroachments by Dutch settlers made the King enter into an agreement with the United Kingdom to become a protectorate in 1868 and, in 1884, a crown colony. It achieved independence in 1966, and was subsequently ruled by the Basotho National Party (BNP) for two decades.
