Brong Ahafo Region was created on 4th April 1959 (by the Brong Ahafo Region Act No. 18 of 1959). The Act defined the area of the Brong Ahafo Region to consist of the northern and the western part of the then Ashanti Region. It included the Prang and Yeji areas that before the enactment of the Act formed part of the Northern Region.
Before the Ashanti Empire was conquered by the British in 1900, the Brong and Ahafo states to the north and northwest of Kumasi (the capital of Ashanti empire and the present Ashanti Region) were within the empire.
Nana Akumfi Ameyaw III traces his ancestry to King Akumfi Ameyaw I (1328-63), under whose reign the Brong Kingdom with its capital at Bono Manso grew to become the most powerful kingdom of its time. Indeed, oral tradition has it that nearly all the different groups of the Akans, including the Asante, trace their origins to Bono after migrating from the “north”.
The first remembered King of the Bono Kingdom is King Asaman, who is credit with leading his Akan people from what may be present day Burkina Faso or even further north, to Bonoland (Buah, 1998). Later migrations led to the Asantes, Fantes, Denkyira and other Akans settling in their present locations. Nana Akumfi Ameyaw is credited with the creation of gold dust as a currency and gold weights as a measure, later developed and adopted by all the other Akan groups, particularly the Asante. Legend has it that he even supported his yam shoots with sticks made of pure gold.
It was when King Opoku Ware of Asante defeated Bono in 1723 and destroyed Bono Manso that the capital moved to Techiman (Takyiman). Techiman and other Bono states therefore came under the Asante Empire until 1948 when Akumfi Ameyaw III led the secession of Bono from Asante, supported by other Bono states such as Dormaa.
The most significant change the British administration in Ashanti brought to the people of the Brong and Ahafo states until 1935 was that it made them independent of Kumasi clan chiefs (Busia, 1951, pp. 165-166).
The British administration worked out a strategy that severed the interference of the Kumasi clan chiefs with the internal affairs of the Brong and Ahafo states. When the Ashanti Confederacy was restored in 1935 by the British administration, however, most of the Brong and Ahafo states saw that their independence from Ashanti was being threatened, because by restoring the Ashanti Confederacy, they were to revert to their former overlords in Kumasi. Though the Brong states joined the Ashanti Confederacy, most of them were not happy with the re-union because they felt their long historical association with Ashanti had brought them nothing
