Sinking of the U.S. vessel the Lusitania
This was in 1916. The German government gave the American government an agreement that German naval forces would not attack unarmed merchant and unarmed passenger vessels. The agreement eventually failed after Germany sunk a cross channel passenger vessel named the Sussex. As a result America entered the war 6th April 1917
One argument for blaming Germany after the sinking of the Lusitania was that it violated international law because it was a civilian vessel. Britain and the United States agreed that the attack was unprovoked. However the Lusitania was carrying arms and ammunition to Great Britain.
Britain argued for years that the Lusitania didn't carry any contraband. When salvage operations began, they acknowledged that there were some 5000 cases of small ammunition aboard. The wreck hasn't been totally explored but we know that it was a little more than a neutral passenger vessel.
Yes,RMS Lusitania was an ocean liner owned by the Cunard Line and built by John Brown and Company of Clydebank, Scotland. Named after the ancient Roman province of Lusitania, which is present day Portugal. She was torpedoed by German U-boat U-20on 7 May 1915 and sank in eighteen minutes, eleven miles (19 km) off the Old Head of Kinsale[4], Ireland, killing about 1,198 of the 1,959 people aboard. The sinking turned public opinion in many countries against Germany and contributed to the entry of theUnited States into World War I.[5] The sinking of Lusitania was a coup for anti-German sentiment, caused great controversy and became an iconic symbol in recruiting campaigns of why the war was being fought. The vessel then was owned by Great Britain. Wikipedia.com

From the Britannica Concise Encyclopedia:The Lusitania was a British ocean liner sunk by a German submarine off the coast of Ireland on May 7, 1915. The British Admiralty had warned the Lusitania to avoid the area and to use the evasive tactic of zigzagging, but the crew ignored these recommendations. Though unarmed, the ship was carrying munitions for the Allies, and the Germans had circulated warnings that the ship would be sunk. The loss of life - 1,198 people drowned, including 128 U.S. citizens - outraged public opinion. The U.S. protested Germany's action, and Germany limited its submarine campaign against Britain. When Germany renewed unrestricted submarine warfare, the U.S. entered World War I in April 1917.
