British forces capture Aden

Background. Sir Robert Grant, Governor of Bombay from 1834 to 1838, advocated for preemptively seizing places of strength to protect the Indian Ocean. In 1838, the ruler of Lahej, Muhsin bin Fadl, ceded territory including Aden to the British. This cession facilitated the subsequent military expedition, which aimed to secure the port and stop pirate attacks on British shipping.

Administrative Context. Following the 1839 capture, Aden became known as the Aden Settlement. Historian RJ Gavin noted that the region's history was marked by administrative confusion. The Resident, the chief British official, often required approval from the Bombay Government, the Government of British India, and the Colonial Office in London before taking action.

Legacy and Aftermath. The city and surrounding area remained under British Empire control from 1839 until independence in 1967. The Royal Marines, who were the first British troops to arrive in 1839, were among the last to leave in 1967. Mail services began in June 1839, shortly after the occupation, though the official post office was not inaugurated until 1857.
