evidence: North Borneo [edit]Between 1658 and 1700, the Sultanate of Sulu acquired the eastern part of the territory of Northern Borneo after helping the Bruneian forces settle a civil war. The Sulu Archipelago then came under the control of the Spanish while the area of Northern Borneo was administered by the British after the sultans of Brunei and Sulu agreed to cede their control. The western and eastern parts of Northern Borneo became known as North Borneo.[4][5] In its process of decolonization beginning in 1946, Great Britain included Sabah in the newly formed Federation of Malaysia. The Philippines, which had already achieved its independence from the United States, protested the formation of Malaysia and filed claims for the whole territory of Northern Borneo under the administration of President Diosdado Macapagal. However, during a meeting to plan Maphilindo, the Philippine government stated that it had no objection to the formation of Malaysia, but claimed that the Sultan of Sulu wanted payment from the British government.[6] The first Malaysian Prime Minister, Tunku Abdul Rahman, said he would return to Kuala Lumpur to protest the Philippines' claim.[6] [...] Map of British North Borneo, highlighting in yellow colour the area covered by the Philippine claim, presented to the Court by the Philippines during the Oral Hearings at the ICJ on 25 June 2001 - ^ Rozan Yunos (September 21, 2008).
