اتحاد الجنوب العربي
When Aden Colony became part of the Federation of South Arabia as the State of Aden the unrest continued. In the federation the ATUC had a large influence in the new assembly and to prevent it seizing control of the federation in 1962 the former Colony of Aden had joined the Federation of South Arabia so that Aden's pro-British assembly members could counter the ATUC's influence.
