 In the early 1990s, the Amalgamated Banks of South Africa (ABSA) group was formed from the merger of United, Allied, and Volkskas Groups with part of the Sage Group.This resulted from the acquisition of the Bankorp Group in 1992.These banks all traded under their own names until 1998, when United, Volkskas, Allied, and TrustBank all merged under the ABSA umbrella.
