adventurer, trader, explorer, and as British consul (1849–54) for the Bights of Benin and Biafra (the coastal area from present-day Benin to Cameroon), a forerunner of British imperial expansion in West Africa, both in his personal enthusiasm and in his systematic intervention in local African politics.

Beecroft's career in Africa began as an official on Fernando Po in 1829 when that island was a temporary British anti-slavery base. He remained there after Britain abandoned the island in 1834, and, in 1843, when Spain reasserted its formal rights to Fernando Po, it appointed him official governor of the island. He also acted as an unofficial British consul in the mid-1840s, helping the British anti-slavery squadron make treaties and settle disputes. By that time he had become known and respected by almost all the coastal chiefs.

As consul for the Bight of Benin (1849–54), Beecroft was mainly expected to safeguard the interests of British merchants. In his time in office he was involved in dealings with several major African societies, including those of Dahomey, Lagos (where the issue of the abolition of the slave trade resulted in a de facto British protectorate), and the Nigerian coastal town of Bonny—a complex affair that resulted in the King's exile. These and other actions of Beecroft systematically eroded the old British African policy of laissez-faire.
