Over the next decade, the newly-founded German East Africa Company would increase German influence in the area by opening customs houses and forming agreements with local chiefs and Sultans. In the last years of the 1880s, however, Arabs opposed to the increased European presence began raiding and killing German settlers. The German East Africa Company requested assistance from the Imperial government, which quickly came in the form of ships and men under the command of newly-appointed Imperial Commissioner Hauptmann Hermann von Wissman. Within a year, the insurrection was crushed, and in 1891, Germany acquired sovereignty over the entire territory.
Regional integration is a major development strategy for the countries of Africa, which all share the aim of continent-wide economic, social and cultural integration by 2028. Trade liberalisation is an important aspect of regional integration. This is to be achieved through regional free trade areas, progressing towards customs union, a common market and ultimately monetary union. The East African Community (EAC) is one of eight regional economic communities recognised by the African Union (AU), and the only one that has a vision of political federation. In the treaty establishing the EAC, the partner states decided to expand and intensify their economic, political, social and cultural integration. Since 1998, German development cooperation has made substantial contributions to the deeper economic and social integration process of the East African Community Partner States.
