It was a combination of two events.
The first was the sinking of the British passenger ship, the Lusitania. There were americas on board and it was not a warship.
The second was the Zimmerman telegram. The British intercepted the telegram that was sent to Mexico by Germany, promising German support for an invasion of the US. England decoded it and sent it to America.
After those events, america troops were mobilized.
The Germans were using U boats to block out our means of shipping goods as well as a ship named Lusintania which carried supplies as well as many passengers, killing 128 people overall to Europe. Also, The United States intercepted a telegram from Germany, the "Zimmerman" note which was to ask for Mexico to go war with the US so the US wouldn't enter World War I. Germany promised to Mexico that they would give Mexico New Mexico,Arizonia,and Texas. So basically we got mad because the Germans were bombing our boats and then the Germans said that if Mexico started a war with the US and kept America from entering WW1 they'd help regain the territory that was given to the United States in the Treaty of Guadalupe Hildalgo after the Mexican American war in the late 1800's
