Answer :
The primary consequence of the sinking of the RMS Lusitania in 1915 was the escalation of anti-German sentiment in the United States. This event, where a German submarine torpedoed the British passenger ship resulting in the loss of American lives, stirred up public outrage and sympathy for the victims.
This incident significantly contributed to the shift in public opinion in the U.S. towards entering World War I on the side of the Allies. The sinking of the Lusitania played a role in swaying public sentiment against Germany and served as a catalyst for the United States eventually joining the war in 1917.
