    The Anglo-Brunei Treaty of Friendship in 1847 distilled the events into a single document, confirming Labuan was ceded to the British in perpetuity.

Background and detail

Background. Labuan had been part of the Sultanate of Brunei for three centuries. Earlier attempts by the British East India Company to establish a station failed, despite the Sultan offering the island as an alternative to Balambangan. These prior failures set the stage for the 1846 acquisition, which occurred against a backdrop of regional instability and pirate threats.

Treaty Context. The Treaty of Labuan was signed on 18 December 1846. Historical sources conflict on the circumstances: some claim the Sultan was threatened by a warship, while others state the cession was a reward for assistance against pirates. The subsequent Anglo-Brunei Treaty of Friendship in 1847 consolidated these events, confirming the cession in perpetuity.

Establishment as Possession. Following the treaty, Labuan became a Crown Colony in 1848. James Brooke was appointed as the first governor and commander-in-chief, with William Napier serving as his lieutenant-governor. This administrative structure marked the transition from treaty acquisition to formal colonial governance, distinct from the earlier failed commercial ventures.
