The Freedmen's Bureau was an agency of the United States Department of War which was created to help newly freed African Americans in their transition from slavery to freedom.
The Bureau helped ex-slaves obtain clothing, food, water, education, health care and jobs so that they could become active members of the society.
Many hospitals and schools were built by the time of its foundation, being education one of the most recognized accomplishments since the Bureau's legislations allowed the construction of state-supported public schools, and its universal nature allowed freed slaves as well as impoverished people obtain education, previously destined to a few.

The United States emerged as a great industrial power following World War I -- the most powerful nation in the world, in fact.
The growth of the United States as the world's leader in industry had been proceeding rapidly already prior to the Great War (which we know as World War I). By 1900, 38% of the world's wealth was held by the United States. By 1914, the US produced as much coal as Britain and Germany combined, as well as producing over 40% of the world's iron.
But before World War I, the United States tended to take an isolationist stance toward other nations. World War I advanced the US into superpower status as a nation that used its industrial might to involve itself in global affairs.
