The Scramble for Africa refers to the period between roughly 1884 and 1914, when the European colonisers partitioned the – up to that point – largely unexplored African continent into protectorates, colonies and ‘free-trade areas’. At the time the colonisers had limited knowledge of local conditions and their primary consideration was to avoid conflict among themselves for African soil. Since no one could foresee the short-lived colonial era, the border design – which endured the wave of independence in the 1960s – had sizable long-lasting economic and political consequences. The Scramble for Africa resulted in several large countries characterised by highly heterogeneous geography and ethnically fragmented populations that limit the ability of governments to broadcast power and build state capacity.
Answer: The Tet Offensive.
The Tet Offensive (officially <em>The General Offensive and Uprising of Tet Mau Than 1968</em>) was one of the largest military campaigns of the Vietnam War, launched on January 30, 1968 by forces of the Viet Cong and North Vietnamese People's Army of the Republic of Vietnam against the forces of the South Vietnamese Army of the Republic of Vietnam, the United States Armed Forces, and their allies.
The offensive shocked the U. S. public and had a strong effect on the U. S. government. Americans had thought that the North Vietnamese were being defeated and were incapable of launching such an ambitious attack. Public support for the war significantly decreased, the media became more critical and the U.S. sought negotiations to end the war.
