Nghị định thư Madrid năm 1885

The Madrid Protocol of 1885 was an agreement between the United Kingdom, Germany, and Spain to recognize the sovereignty of Spain over the Sulu Archipelago as well as the limit of Spanish influence in the region. Under the agreement, Spain relinquished all claim to Borneo.

The Spanish Government renounces, as far as regards the British Government, all claims of sovereignty over the

territories of the continent of Borneo, which belong, or which have belonged in the past to the Sultan of Sulu (Jolo), and

which comprise the neighbouring islands of Balambangan, Banguey, and Malawali, as well as all those comprised within

a zone of three maritime leagues from the coast, and which form part of the territories administered by the Company styled the "British North Borneo Company".

Another important point regarding the agreement relates to Article IV, which guarantees no restriction on trade to the parties of the protocol within the Sulu Archipelago and North Borneo.
