As a result of the various territorial shifts between the Bunak kingdoms, however, the border between the two colonial powers of Portugal and the Netherlands remained a long-standing issue and was the subject of lengthy negotiations. In Lakmaras District, there were several deaths in the same year in clashes between Dutch and Portuguese troops. The Dutch claim to Maucatar was justified by Lakmaras sovereignty, which created a link to Maucatar. Meanwhile, Lakmaras had become subject to the kingdom of Lamaquitos, and this was part of the Portuguese sphere of power established by the Treaty of Lisbon in 1859. Maucatar would have failed as an Portugal enclave, according to the agreements that were already in place. On the other hand, the state of Tahakay (Tahakai, Tafakay, Takay; now in southern Lamaknen district) belonging to Portugal had subsequently become part of Lamaknen district. Tahakay, however, belonged to the Portuguese sphere of influence, while Lamaknen district belonged to the Dutch. Portugal opposed this loss in the negotiations of 1902, and therefore demanded the entire Dutch territories in the center of Timor. A compromise was reached with The Hague Convention of October 1, 1904: Portugal was to receive Maucatar, in exchange for the Portuguese enclave Noimuti in West Timor, and the border areas of Tahakay, Tamira Ailala and Tamiru Ailala of Lamaknen District. Portugal respected the treaty until 1909, but then there was a dispute over the border crossing on the eastern border of Oecusse District. In 1910, the Netherlands took advantage of the overthrow of the Portuguese monarchy in order to regain Lakmaras with the help of European and Javanese troops.
