The massacre at Wounded Knee in 1890 occurred in response to "<span>d. the discovery of gold at Pike’s Peak" since this was the main reason why settlers were there, although this was not exactly a "response". </span>
The United States tried to remain neutral during World War I, but numerous things occured that tipped the balance and made the U.S. finally declare war. The first thing was the sinking of the Lusitania in 1915, by Germany. The Lusitania was a ship carrying over 1,000 innocent passengers, with over 100 Americans onboard, a German U-boat sank the ship, ultimately killing everyone. Americans were furious about this, but it was not enough for the United States to declare war and join the Allied powers during World War I. The Zimmerman Telegram was the occurrence that finally made President Woodrow Wilson finally declare war. The Zimmerman Telegram was supposed to be a secret telegram to Mexico from the Germans, however it was decoded and brought to the United States' attention in 1917. This telegram stated if Mexico sided with Germany during World War I, and attacked the states, when Germany won the war they promised they would give Mexico territories. This was a huge threat, as Mexico bordered the United States, and it was the final straw into the United States entering World War I. On April 6, 1917, after the speech of Woodrow Wilson, the United States had officially declared war on Germany and entered World War I as one of the Allied powers.
