The State of Aden (Arabic: ولاية عدن Wilāyat ʿAdan) was a state constituted in Aden within the Federation of South Arabia. Following its establishment on 18 January 1963 Sir Charles Hepburn Johnston stepped down as the last Governor of Aden.
In spite of the hopes placed in the Federation, the insurgency in Aden escalated and hastened the end of British presence in the territory with the British leaving Aden by the end of November 1967.
