i thought it was the assassination of ferdinand?
Answer: The assassination of Archduke Ferdinand provoked Austria-Hungary to declare war on Serbia, which dragged the rest of Europe into World War I. The assassination, however, was of no grand concern of the average United States citizen.
There were three main events that led to USA's full involvement in WW1.
Including: The sinking of the Lusitania
The Zimmerman telegram
And the Unrestricted submarine warfare (done by German U-Boats)
Previously, involvement in WW1 included shipment of weaponry and technology.
sinking of lusitania
Japan attack on Pearl Harbor
Two of them might be the Zimmerman telegram and the sinking of the Lusitania
No, World War 1 ended in 1918 and the attack on Pearl Harbor was on December 7, 1941. Pearl Harbor was the event that provoked the US to enter World War 2, not 1.
The attack on Pearl Harbor by the Japanese on 12-7-41 was the event that provoked the Congress and Senate to vote the next day for declaring war on the Japanese. I am sure that is one of the options on your homework question.
