Question: Where did Germany have imperial interests, besides the continent where the river that is the drainage of the southwest plain of Congo is located?

full_context: Document 1: Republic of the Congo: The Republic of the Congo (French: République du Congo), also known as Congo, Congo Republic, West Congo[citation needed], or Congo-Brazzaville, is a country located in Central Africa. It is bordered by five countries: Gabon to the west; Cameroon to the northwest; the Central African Republic to the northeast; the Democratic Republic of the Congo to the east and south; and the Angolan exclave of Cabinda to the southwest.
Document 2: Geography of Angola: Angola is located on the western Atlantic Coast of Central Africa between Namibia and the Republic of the Congo. It also is bordered by the Democratic Republic of the Congo and Zambia to the east. The country consists of a sparsely watered and somewhat sterile coastal plain extending inland for a distance varying from . Slightly inland and parallel to the coast is a belt of hills and mountains and behind those a large plateau. The total land size is . It has an Exclusive Economic Zone of .
Document 3: Republic of the Congo: The southwest of the country is a coastal plain for which the primary drainage is the Kouilou-Niari River; the interior of the country consists of a central plateau between two basins to the south and north. Forests are under increasing exploitation pressure.
Document 4: Imperialism: A resurgence came in the late 19th century, with the Scramble for Africa and major additions in Asia and the Middle East. The British spirit of imperialism was expressed by Joseph Chamberlain and Lord Rosebury, and implemented in Africa by Cecil Rhodes. The pseudo-sciences of Social Darwinism and theories of race formed an ideological underpinning during this time. Other influential spokesmen included Lord Cromer, Lord Curzon, General Kitchner, Lord Milner, and the writer Rudyard Kipling. The British Empire was the largest Empire that the world has ever seen both in terms of landmass and population. Its power, both military and economic, remained unmatched.
Document 5: Imperialism: However, in 1883–84 Germany began to build a colonial empire in Africa and the South Pacific, before losing interest in imperialism. Historians have debated exactly why Germany made this sudden and short-lived move.[verification needed] Bismarck was aware that public opinion had started to demand colonies for reasons of German prestige. He was influenced by Hamburg merchants and traders, his neighbors at Friedrichsruh. The establishment of the German colonial empire proceeded smoothly, starting with German New Guinea in 1884.
Document 6: History of colonialism: Africa was the target of the third wave of European colonialism, after that of the Americas and Asia. Many European statesmen and industrialists wanted to accelerate the Scramble for Africa, securing colonies before they strictly needed them. As a champion of Realpolitik, Bismarck disliked colonies and thought they were a waste of time, but his hand was forced by pressure from both the elites and the general population which considered the colonization a necessity for German prestige. German colonies in Togoland, Samoa, South - West Africa and New Guinea had corporate commercial roots, while the equivalent German - dominated areas in East Africa and China owed more to political motives. The British also took an interest in Africa, using the East Africa Company to take over what are now Kenya and Uganda. The British crown formally took over in 1895 and renamed the area the East Africa Protectorate.
Document 7: Mitumba Mountains: The Mitumba Mountain range stretches along the Western Rift Valley in Eastern Congo (DRC), west of lake Tanganyika. The two main peaks, Mount Kahuzi (3,308 m) and Mount Biéga (2,790 m) are extinct volcanoes.
Document 8: Imperialism: Not a maritime power, and not a nation-state, as it would eventually become, Germany’s participation in Western imperialism was negligible until the late 19th century. The participation of Austria was primarily as a result of Habsburg control of the First Empire, the Spanish throne, and other royal houses.[further explanation needed] After the defeat of Napoleon, who caused the dissolution of that Holy Roman Empire, Prussia and the German states continued to stand aloof from imperialism, preferring to manipulate the European system through the Concert of Europe. After Prussia unified the other states into the second German Empire after the Franco-German War, its long-time Chancellor, Otto von Bismarck (1862–90), long opposed colonial acquisitions, arguing that the burden of obtaining, maintaining, and defending such possessions would outweigh any potential benefits. He felt that colonies did not pay for themselves, that the German bureaucratic system would not work well in the tropics and the diplomatic disputes over colonies would distract Germany from its central interest, Europe itself.
Document 9: Mayombe: Mayombe (or Mayumbe) is a geographic area on the western coast of Africa occupied by low mountains extending from the mouth of the Congo River in the south to the Kouilou-Niari River to the north. The area includes parts of the Democratic Republic of the Congo, Angola (Cabinda Province), the Republic of the Congo and Gabon.
Document 10: Congo River: Railways now bypass the three major falls, and much of the trade of Central Africa passes along the river, including copper, palm oil (as kernels), sugar, coffee, and cotton. The river is also potentially valuable for hydroelectric power, and the Inga Dams below Pool Malebo are first to exploit the Congo river.
Document 11: Scramble for Africa: The Berlin Conference of 1884, which regulated European colonisation and trade in Africa, is usually referred to as the starting point of the scramble for Africa. Consequent to the political and economic rivalries among the European empires in the last quarter of the 19th century, the partitioning, or splitting up of Africa was how the Europeans avoided warring amongst themselves over Africa. The later years of the 19th century saw the transition from ``informal imperialism ''(hegemony), by military influence and economic dominance, to direct rule, bringing about colonial imperialism.
Document 12: Republic of the Congo: Since the country is located on the Equator, the climate is consistent year-round, with the average day temperature being a humid 24 °C (75 °F) and nights generally between 16 °C (61 °F) and 21 °C (70 °F). The average yearly rainfall ranges from 1,100 millimetres (43 in) in south in the Niari Valley to over 2,000 millimetres (79 in) in central parts of the country. The dry season is from June to August while in the majority of the country the wet season has two rainfall maxima: one in March–May and another in September–November.
Document 13: Republic of the Congo: The Republic of the Congo's sparse population is concentrated in the southwestern portion of the country, leaving the vast areas of tropical jungle in the north virtually uninhabited. Thus, Congo is one of the most urbanized countries in Africa, with 70% of its total population living in a few urban areas, namely in Brazzaville, Pointe-Noire or one of the small cities or villages lining the 534-kilometre (332 mi) railway which connects the two cities. In rural areas, industrial and commercial activity has declined rapidly in recent years, leaving rural economies dependent on the government for support and subsistence.
Document 14: Yumbi: Yumbi is a town and territory in Plateaux District of Bandundu Province in the Democratic Republic of the Congo. It lies on the eastern bank of the Congo River between Bolobo and Lukolela.
Document 15: Republic of the Congo: Congo is located in the central-western part of sub-Saharan Africa, along the Equator, lying between latitudes 4°N and 5°S, and longitudes 11° and 19°E. To the south and east of it is the Democratic Republic of Congo. It is also bounded by Gabon to the west, Cameroon and the Central African Republic to the north, and Cabinda (Angola) to the southwest. It has a short coast on the Atlantic Ocean.
