The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war. In 1783, in the Treaty of Paris, the British monarchy acknowledged the independence of the Thirteen Colonies, leading to the establishment of the United States as an independent and sovereign nation.

It was fought from September 26, 1918, until the Armistice of November 11, 1918, a total of 47 days. The Meuse–Argonne offensive was the largest in United States military history, involving 1.2 million American soldiers, sailors and marines, along with 800,000 French and 850 Siamese personnel. It is also the deadliest campaign in the history of the United States Army, resulting in over 350,000 casualties, including 28,000 German lives, 26,277 American lives and about 35,000 French lives.

The Spanish Civil War was fought from 1936 to 1939 between the Republicans and the Nationalist rebels. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic and included socialists, anarchists, communists, and separatists, supported by the Soviet Union. The opposing Nationalists were an alliance of fascist Falangists, monarchists, conservatives, and traditionalists, supported by Nazi Germany and Fascist Italy and initially led by a military junta, until General Francisco Franco was appointed supreme leader on 1 October 1936 for what he called the Spanish State. Due to the international political climate at the time, the war was variously viewed as class struggle, religious struggle, or struggle between republican democracy and dictatorship, revolution and counterrevolution, or fascism and communism. The Nationalists won the war in early 1939, and ruled Spain until Franco's death in November 1975.

During presidential election campaigns in the United States, it has become customary for the candidates to engage in one or more debates. The topics discussed in the debate are often the most controversial issues of the time, and arguably elections have been nearly decided by these debates.

The debates are targeted mainly at undecided voters; those who tend not to be partial to any political ideology or party.
