Formed as an anti-communist labour international, the International Co
nfederation of Free Trade Unions (ICFTU) nevertheless experienced inte
rnal conflict over the appropriate approach to communism. The differen
t perspectives of the two largest affiliates, the British TUC and the
American AFL-CIO, caused disharmony and ultimately near organizational
paralysis until it forced a change of leadership. Caught between thes
e rival positions, the ICFTU secretariat's relations with the AFL-CIO
were initially the most strained, but as the International extended it
s activity in Africa, in a bid to outflank communist organization amon
g labour, relations with the TUC also deteriorated over the correct st
ance on nationalism and colonialism.
