Tio Kingdom in the context of "Boma Kingdom"

The Republic of the Congo, also known as Congo-Brazzaville, the Congo Republic or simply the Congo (its name from 1971 to 1997; the last ambiguously also referring to the neighbouring Democratic Republic of the Congo), is a country located on the western coast of Central Africa to the west of the Congo River. It is bordered to the west by Gabon, to the northwest by Cameroon, to the northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to the south by the Angolan exclave of Cabinda, and to the southwest by the Atlantic Ocean.

The region was dominated by Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. From the 13th century, the present-day territory was dominated by a confederation led by Vungu which included Kakongo and Ngoyo. The Tio Kingdom emerged in the 14th century, and Loango in the 16th century. In the late 19th century France colonised the region and incorporated it into French Equatorial Africa. The Republic of the Congo was established on 28 November 1958 and gained independence from France in 1960. It was a Marxist–Leninist state from 1969 to 1992, under the name People's Republic of the Congo (PRC). The country has had multi-party elections since 1992, but a democratically elected government was ousted in the 1997 Republic of the Congo Civil War. Denis Sassou Nguesso has been president since 1979, except for the period from 1992 to 1997.

Mwene Muji was a polity proposed by John Thornton, located around Lake Mai-Ndombe in the Congo Basin, likely stretching south to Idiofa. It bordered the Tio Kingdom among others to its southwest. Mwene Muji dominated the region of the Lower Kasai. It was ruled by the BaNunu, holding the titles of Ntote. Its unity crumbled in the early-17th century, with the Boma Kingdom, Yaka Kingdom, and Bozanga breaking away. Mwene Muji entered a further severe decline in the 19th century and was surpassed by the Boma Kingdom, on the eve of Belgian conquest in the early-20th century. Its 'empire' status is pending on further archaeological research.

The first written record of Mwene Muji came in 1591 by Italian humanist Filippo Pigafetta. The name Monemugi was erroneously applied to Unyamwezi in modern-day Tanzania near Lake Malawi.

After the introduction of multi-party elections in 1992, the democratically elected government was overthrown during the civil war, after which Denis Sassou Nguesso, who had previously served as president from 1979 to 1992, returned to office in 1997. He has remained president since then.
