World War I
The American Revolutionary War was the ongoing event that led to the Articles of Confederation. The articles were ratified in 1781, and were eventually replaced by the US Constitution.
The underlying cause of the Spanish American War was US public support for Cuban independence. The triggering event was the mysterious sinking of the USS Maine on 15 February 1898 which led to a declaration of War. The net effect of the War was Cuban Independence and the loss of Spain's New World Empire.
