The Socialist Labor Party of America, which had helped to found the IWW in Chicago, also formed the first IWW branches in Australia. The (SLP) withdrew from the IWW in 1908, primarily over objections to the SLP's insistence that the party should exercise control over working class organizations. The SLP formed its own industrial union organization, calling it by the same name, the Industrial Workers of the World (IWW). The original IWW began to refer to itself as the Red IWW, and the SLP group as the Yellow IWW. The SLP-originated IWW renamed itself the Workers' International Industrial Union (WIIU) in 1915.
