Concept note-1: -Germany’s resumption of submarine attacks on passenger and merchant ships in 1917 became the primary motivation behind Wilson’s decision to lead the United States into World War I.
Concept note-2: -World War I was in many ways the beginning of the 20th-century civil rights movement. The war created opportunities for African Americans to demand their civil rights, in and outside of the Army.
Concept note-3: -The Senate has, at times, rejected treaties when its members felt their concerns were not adequately addressed. In 1919 the Senate rejected the Treaty of Versailles, which formally ended World War I, in part because President Woodrow Wilson had failed to take senators’ objections to the agreement into consideration.
Concept note-4: -World War I started in 1914. In 1915, Italy entered the war. The USA entered the war in 1917. After the end of World War I in 1918, the Treaty of Versailles was signed in 1919.
