The Gibraltar macaque population was under the care of the British Army and later the Gibraltar Regiment from 1915 to 1991, who carefully controlled a population that initially consisted of a single troop. An officer was appointed to supervise their welfare, and a food allowance of fruit, vegetables and nuts was included in the budget. Births were gazetted in true military fashion, and each new arrival was named. They were named after governors, brigadiers and high ranking officers. Any ill or injured monkey was taken to Royal Naval Hospital and received the same treatment as would an enlisted service man. Following the withdrawal of the British garrison, the Government of Gibraltar took over responsibility for the monkeys.
