Techiman: History
=== Bono-Tekyiman ===
The town of Techiman used to be a part of the Bono state. After Bono Manso, capital of the Bono state, was destroyed by the Asante Empire in 1723 during the Asante-Bono war, the capital was moved to Techiman in 1740, which ruled a much-reduced kingdom under Asante sovereignty. As a vassal, Techiman joined the Asante in wars against Gonja in 1802, Gyaman in 1818, and Ewe in the 1860s.
After the Third Anglo–Asante War, a confederation of Brong states led by Gyaman which included Techiman attempted to secede from the empire with British protection. In 1877, Techiman was destroyed, with the population fleeing to Gyaman. Only in 1896 were did Asantehene Prempeh I allow them to return.
Between 1896 and 1901 Techiman and the other Brong states were part of the Asante 'protectorate', but were administered separately by the British. Techiman regained control of several villages that had been taken by the Asante in 1723. A series of colonial reorganizations, however, brought Techiman back under the Asantehene's purview.
Techiman joined the Asante Confederacy Council of chiefs in April 1936, but the Techimanhene quickly found that the council would not be the free association of states that he expected. Techiman, along with Dormaa, Drobo, Abease, Suma-Ahenkro and Antepim-Domase, seceded from the Confederacy in 1952.
A referendum in 2018 was passed with the focus of creating new regions in Ghana, which resulted in Techiman being selected as the capital of the newly created Bono East Region.
