As a Homeland leader, the power of Buthelezi depended on the South African state and economy. With anti-apartheid leaders inside South Africa and abroad demanding sanctions, Buthelezi came to be regarded more and more as a government puppet, along with other Bantustan leaders. His tribal loyalties and focus on ethnic interests over national unity were also criticised as contributing to the divisive programme of Inkatha. This led to a virtual civil war between Zulu loyalist supporters and ANC members in KwaZulu-Natal.
