For the history of Ghana, here is the list of rulers of the Akan state of Akuapem Guan. The Guan are believed to have begun to migrate from the Mossi region of modern Burkina Faso around A.D. 1000. Moving gradually through the Volta valley in a southerly direction, they created settlements along the Black Volta, throughout the Afram Plains, in the Volta Gorge, and in the Akuapem Hills before moving farther south onto the coastal plains. Some scholars postulate that the wide distribution of the Guan suggests that they were the Neolithic population of the region. Later migrations by other groups such as the Akan, Ewe, and Ga-Adangbe into Guan-settled areas would then have led to the development of Guan-speaking enclaves along the Volta and within the coastal plains. The Guan have been heavily influenced by their neighbours. The Efutu, a subgroup of the Guan, for example, continue to speak Guan dialects, but have adopted (with modifications) the Fante version of some Akan institutions and the use of some Fante words in their rituals. As far as the other Guan subgroups are concerned, the Anum-Boso speak a local Ewe dialect, whereas the Larteh and Kyerepong have customs similar to Akwapim groups. Constituting about a quarter of the Guan, the Gonja to the north have also been influenced by other groups. The Gonja are ruled by members of a dynasty, probably Mande in origin. The area is peopled by a variety of groups, some of which do not speak Guan. The ruling dynasty, however, does speak Guan, as do substantial numbers of commoners. Although neither the rulers nor most of the commoners are Muslims, a group of Muslims accompanied the Mande invaders and have since occupied a special position as scribes and traders. Led by their leader Gyedu Nkansa, a quarter of the Guan settled in present-day Akuapem mountains. Prior to the founding of Akuapem State, the institution of chieftaincy as we know of today was non-existent. The leadership of highland community made up mainly of Guans and the Kyerepongs consisted of priests and priestesses. Nana Offei Kwasi Agyeman of the Aduana fame, a trader from Gyakiti, and a chief in his own right, had already left Akwamu with his people to live at a village called Adenya. Surrounded by his band of Mpoti Asafo with their proverbial seven guns. He later settled at Boampong (Kaabi) the northern part of present-day
