Cession of Labuan by Brunei

Date: December 24, 1846 • Location: Labuan, Malaysia

The Sultanate of Brunei ceded the island of Labuan to the British Empire.

The Sultanate of Brunei or simply Brunei, also known as the Bruneian Empire, was a Malay sultanate centred around Brunei on the northern coast of Borneo in Southeast Asia. Brunei became a sovereign state around the 15th century, when it substantially expanded after the fall of Malacca to the Portuguese, extending throughout coastal areas of Borneo and the Philippines, before it declined in the 17th and 18th centuries. It became a British protectorate in the 19th century.
