What prompted President Wilson to bring the US in the war war one?

President Wilson was prompted to bring the U.S. into World War I primarily due to unrestricted submarine warfare by Germany, which threatened American lives and commerce, exemplified by the sinking of the Lusitania in 1915. Additionally, the revelation of the Zimmermann Telegram, in which Germany sought an alliance with Mexico against the U.S., heightened tensions. Wilson also aimed to make the world "safe for democracy," believing U.S. involvement was necessary to shape a post-war order that aligned with democratic ideals.
