They fought against the Central Powers, the two main countries being Germany and Austria-Hungary. The US joined after Germany re-commenced unrestricted submarine warfare after having ceased at the request of Wilson, but they resumed it after pressure from the Navy forced the Kaiser to. The naval blockade from Britain was destroying Germany at home, and they had little choice but to resume. Another cause was the infamous Zimmermann telegram, which Germany sent to Mexico trying to coax them into fighting America, with Japan's help. They miscalculated the time it would take America to mobilize, thinking it would take many months, but instead only took weeks. Germany would make the same mistake in WW2 against Russia this time.
