The United States was prompted to enter World War I primarily due to the unrestricted submarine warfare conducted by Germany, which threatened American shipping and lives. The sinking of the British ocean liner RMS Lusitania in 1915, resulting in the deaths of 128 Americans, heightened tensions. Additionally, the interception of the Zimmermann Telegram in early 1917, in which Germany proposed a military alliance with Mexico against the U.S., further galvanized public and political support for intervention. As a result, the U.S. declared war on Germany on April 6, 1917.

The event that triggered the fighting between the north and south was when Jefferson Davis ordered that Fort Sumpter be attacked. This started the American Civil War. States rights and slavery were also trigger points.
The war between the Union and the Confederacy, known as the American Civil War, was triggered by the attack on Fort Sumter in South Carolina on April 12, 1861. This event followed the secession of several Southern states from the Union, driven by issues such as states' rights and slavery. The Confederate forces fired upon the federal fort, marking the beginning of armed conflict and leading to the full-scale war between the North and South.
The secession of the various Southern states (following South Carolina's lead) was triggered by Lincoln's rejection of the final compromise, because it would have allowed some extension of slavery. The actual combat was triggered by the firing of Confederate artillery at the Union garrison on the island of Fort Sumter in Charleston Harbour.
