Explanation: William McKinley was born in 1843. He became the 25th U.S. president and he was the last Civil War veteran to become president. William worked to make the United states a strong world power.
In 1896 he became the president of the United States. He led the country to win the Spanish-American War which was one of the shorter wars fought in history between the United States of America and Spain in 1896. William also created a way of protecting people's money.
