WORLD HISTORY

Detailed explanation-1: -The sinking of the Lusitania was the most notorious and deadly of several German submarine attacks in early 1917–attacks that were a key factor in the United States’ decision to abandon a policy of neutrality and enter the war.

Detailed explanation-2: -Britain’s blockade across the North Sea and the English Channel cut the flow of war supplies, food, and fuel to Germany during World War I. Germany retaliated by using its submarines to destroy neutral ships that were supplying the Allies.

Detailed explanation-3: -Explanation: In May 1915, the Lusitania was sank by a German U-Boat (submarine) off the coast of Ireland. About 1200 lives were lost, many hundreds of whom were American. Naturally, the Americans became angry that the Germans sank a ship full of passengers without provocation.

Detailed explanation-4: -President Woodrow Wilson, however, took a cautious approach to responding to the attack, demanding from Germany an apology, compensation for American victims, and a pledge to discontinue unannounced submarine warfare.
