Ghana, formally the Republic of Ghana, is a West African nation. It is bordered by the Gulf of Guinea and the Atlantic Ocean to the south, the Ivory Coast to the west, Burkina Faso to the north, and Togo to the east. Ghana has a total land area of 238,535 km2 (92,099 sq mi), with different biomes ranging from coastal savannas to tropical rain forests. Ghana is the second-most populous nation in West Africa, behind Nigeria, with a population of about 31 million people. Accra is the capital and biggest city; other notable cities include Kumasi, Tamale, and Sekondi-Takoradi.
The Bono Kingdom of the 11th century was Ghana's first permanent state. Over the ages, several kingdoms and empires arose, the most powerful of which were the Kingdom of Dagbon in the north and the Ashanti Empire in the south. The Portuguese Empire, followed by various other European nations, battled the region for commercial rights beginning in the 15th century until the British eventually achieved control of the coast by the late 19th century. Ghana's present boundaries emerged after more than a century of colonialism, covering four independent British colonial territories: the Gold Coast, Ashanti, the Northern Territories, and British Togoland. On March 6, 1957, they were united as an independent dominion within the Commonwealth of Nations, becoming the first colony in Sub-Saharan Africa to acquire sovereignty. Ghana thereafter gained prominence in decolonization efforts and the Pan-African movement.
Ghana is a multi-ethnic nation with a diversified demographic, language, and religious groupings; although the Akan are the most populous ethnic group, they are just a minority. The great majority of Ghanaians (71.3 percent) are Christian, with about a fifth Muslim and a tenth professing traditional religions or claiming no religion. Ghana is a unitary constitutional democracy governed by a president who serves as both the head of state and the head of government. It has had one of the freest and most stable administrations on the continent since 1993, and it does rather well in terms of healthcare, economic growth, and human development. As a result, Ghana wields considerable power in West Africa and is deeply involved in international politics, having joined the Non-Aligned Movement, the African Union, the Economic Community of West African States (ECOWAS), and the Group of 24 (G24), and the Commonwealth of Nations.
