William B. McKinley was the 25th President of the United States, serving from 1897 until his assassination in 1901. He is known for leading the nation during the Spanish-American War, which resulted in the U.S. acquiring territories like Puerto Rico, Guam, and the Philippines. McKinley's presidency also focused on economic policies, promoting protective tariffs to support American industry.

After his assassination, Vice President Theodore Roosevelt succeeded him, marking a significant shift in American politics. McKinley remains a notable figure in U.S. history for these developments.
