full_context: Document 1: History of Angola: Angola is a country in southwestern Africa. The country's name derives from the Kimbundu word for king. It was first settled by San hunter - gatherer societies before the northern domains came under the rule of Bantu states such as Kongo and Ndongo. From the 15th century, Portuguese colonists began trading, and a settlement was established at Luanda during the 16th century. Portugal annexed territories in the region which were ruled as a colony from 1655, and Angola was incorporated as an overseas province of Portugal in 1951. After the Angolan War of Independence which ended with an army mutiny and leftist coup in Lisbon, Angola's independence was achieved on November 11, 1975 through the Alvor Agreement. After independence, Angola later entered a period of civil war that lasted up until 2002.

Document 7: Northern Seven Years' War: 1762 brought two new countries into the war. Britain declared war against Spain on 4 January 1762; Spain reacted by issuing their own declaration of war against Britain on 18 January. Portugal followed by joining the war on Britain's side. Spain, aided by the French, launched an invasion of Portugal and succeeded in capturing Almeida. The arrival of British reinforcements stalled a further Spanish advance, and the Battle of Valencia de Alcántara saw British-Portuguese forces overrun a major Spanish supply base. The invaders were stopped on the heights in front of Abrantes (called the pass to Lisbon) where the Anglo-Portuguese were entrenched. Eventually the Anglo-Portuguese army, aided by guerrillas and practicing a scorched earth strategy, chased the greatly reduced Franco-Spanish army back to Spain, recovering almost all the lost towns, among them the Spanish headquarters in Castelo Branco full of wounded and sick that had been left behind.
Document 8: British Empire: Britain's fears of war with Germany were realised in 1914 with the outbreak of the First World War. Britain quickly invaded and occupied most of Germany's overseas colonies in Africa. In the Pacific, Australia and New Zealand occupied German New Guinea and Samoa respectively. Plans for a post-war division of the Ottoman Empire, which had joined the war on Germany's side, were secretly drawn up by Britain and France under the 1916 Sykes–Picot Agreement. This agreement was not divulged to the Sharif of Mecca, who the British had been encouraging to launch an Arab revolt against their Ottoman rulers, giving the impression that Britain was supporting the creation of an independent Arab state.
Document 9: History of Germany during World War I: During World War I, the German Empire was one of the Central Powers that lost the war. It began participation in the conflict after the declaration of war against Serbia by its ally, Austria - Hungary. German forces fought the Allies on both the eastern and western fronts, although German territory itself remained relatively safe from widespread invasion for most of the war, except for a brief period in 1914 when East Prussia was invaded. A tight blockade imposed by the Royal Navy caused severe food shortages in the cities, especially in the winter of 1916 -- 17, known as the Turnip Winter. At the end of the war, Germany's defeat and widespread popular discontent triggered the German Revolution of 1918 -- 19 which overthrew the monarchy and established the Weimar Republic.
Document 10: Germans: In 1866, the feud between Austria and Prussia finally came to a head. There were several reasons behind this war. As German nationalism grew strongly inside the German Confederation and neither could decide on how Germany was going to be unified into a nation-state. The Austrians favoured the Greater Germany unification but were not willing to give up any of the non-German-speaking land inside of the Austrian Empire and take second place to Prussia. The Prussians however wanted to unify Germany as Little Germany primarily by the Kingdom of Prussia, whilst excluding Austria. In the final battle of the German war (Battle of Königgrätz) the Prussians successfully defeated the Austrians and succeeded in creating the North German Confederation.
Document 11: History of São Tomé and Príncipe: By the late 1950s, when other emerging nations across the African Continent were demanding independence, a small group of São Toméans had formed the Movement for the Liberation of São Tomé and Príncipe (MLSTP), which eventually established its base in nearby Gabon. Picking up momentum in the 1960s, events moved quickly after the overthrow of the Caetano dictatorship in Portugal in April 1974. The new Portuguese regime was committed to the dissolution of its overseas colonies; in November 1974, their representatives met with the MLSTP in Algiers and worked out an agreement for the transfer of sovereignty. After a period of transitional government, São Tomé and Príncipe achieved independence on July 12, 1975, choosing as its first president the MLSTP Secretary General Manuel Pinto da Costa.

Document 14: Portugal: In the 20th century, Portugal engaged in two major conflicts: World War I and the Portuguese Colonial War (1961–1974). After the end of the Portuguese Empire in 1975, the Portuguese Armed Forces have participated in peacekeeping missions in East Timor, Bosnia, Kosovo, Afghanistan, Somalia, Iraq (Nasiriyah) and Lebanon. Portugal also conducted several independent unilateral military operations abroad, as were the cases of the interventions of the Portuguese Armed Forces in Angola in 1992 and in Guinea-Bissau in 1998 with the main objectives of protecting and withdrawing of Portuguese and foreign citizens threatened by local civil conflicts.
Document 15: German campaign in Angola: Before the official declaration of war between Germany and Portugal (March 1916), German and Portuguese troops clashed several times on the border between German South West Africa and Portuguese Angola.
