The Dutch Reformed Church in Botswana was founded by Swiss missionaries led by Rev. Henri Gronin begun working in 1863 among the tribe Bakgatla, Kgafela in Saulsport and Rustenburg in South Africa. In 1870 part of the tribe moved north to Botswana and the missionaries followed them. The great chief was baptised and most of the tribe followed him. In 1966 when Botswana become independent, a Synod of the Reformed Church was formed. In the 1970s the church gained independence. The church in the following years expanded to Basarwa, Bakalanga and Bakgatla.
