The post-1991 multi-party political parties were again largely based on ethnicity. At the dawn of independence, the Kenya African National Union (Kanu), through Tom Mboya, managed to secure a merger with the Kenya African Democratic Union (Kanu). The British colonial government had outlawed the formation of national parties in 1955 after banning the Kenya African Union (Kau) in 1953. Hence the seed of tribally inclined political parties was deliberately sown by the colonial government as a divide-and-rule strategy. They sought belonging in a national political outfit.
