of the tribal leaders from the Aden Protectorates, where broad agreement was reached that they should "seek some form of close association with each other". In May 1958 a state of emergency was declared and there were a number of bombings until the arrest of the principal instigators in July. However, in October 1958 there was a general strike, which was accompanied by widespread rioting and disorder which ended in the deportation of 240 Yemenis from Aden, as claimed by author Gillian King: "By ignoring the views of the local labour force, the British pushed much of the Arab population into opposition against their rule, who previously had been by no means captivated by Nasser".
