The story
The bank was founded in 1962 in Dar es Salaam. Branches were soon opened in Nairobi and Mombasa, Kenya and in Kampala, Uganda. When Tanzania nationalized private banks in 1967, the bank moved its headquarters to Nairobi. Following political changes in Uganda in 1971, the bank sold its assets in that country. In July 2005, the Commercial Bank of Africa (CBA) acquired majority shareholding in First American Bank of Kenya, which at the time had a Tanzanian subsidiary called United Bank of Africa. In 2007, United Bank of Africa rebranded to Commercial Bank of Africa (Tanzania), returning the brand to the country since 1967. In January 2014, CBA opened its first branch in Uganda.
