Question: When did the country where Pieter van Abeele was born refuse to surrender to Namibia?

South Africa occupied the colony in 1915 after defeating the German force during World War I and administered it from 1919 onward as a League of Nations mandate territory. Although the South African government desired to incorporate 'South-West Africa' into its territory, it never officially did so, although it was administered as the de facto 'fifth province', with the white minority having representation in the whites-only Parliament of South Africa, as well as electing their own local administration the SWA Legislative Assembly. The South African government also appointed the SWA administrator, who had extensive powers. The Herero Chief's Council submitted a number of petitions to the UN calling for it to grant Namibia independence during the 1950s. During the 1960s, when European powers granted independence to their colonies and trust territories in Africa, pressure mounted on South Africa to do so in Namibia. In 1966 the International Court of Justice dismissed a complaint brought by Ethiopia and Liberia against South Africa's continued presence in the territory, but the U.N. General Assembly subsequently revoked South Africa's mandate, while in 1971 the International Court of Justice issued an "advisory opinion" declaring South Africa's continued administration to be illegal. Following the League's replacement by the United Nations in 1946, South Africa refused to surrender its earlier mandate to be replaced by a United Nations Trusteeship agreement, requiring closer international monitoring of the territory's administration (along with a definite independence schedule). <SEP> foppe van aitzema (ca. 1580 dokkum—october 1637, vienna), a son of schelte van aitzema, a man of noble birth, was council to the duke of brunswick when he became resident to the state of the united netherlands in hamburg. <SEP> It was established in 1995.

He perfected the technique of pressing hollow medals. He created the two sides of the medal separately and combined them with a ring of metal. His works are said to be the best of their time, and consist mostly of memorial and portrait medals. They depict several members of the House of Orange, Admiral Maarten Tromp, Jan Wolfert van Brederode, Charles X of Sweden and Charles II of England. He also made commemorative medals for the destruction of the English fleet and the peace of 1667, as well as one showing the granting of the coat of arms to the city of Amsterdam by Count William II of Holland and Emperor Maximilian I. He died in Amsterdam.
