After U.S. President William McKinley was assassinated in 1901, Theodore Roosevelt became the new U.S. President. Roosevelt's first term was notable for his trust busting, his successful arbitration in and resolution of a 1902 strike of 150,000 Pennsylvania coal miners, his advocacy against lynching, his conservation efforts, and the Panama Canal Treaty. In 1904, Roosevelt easily defeated Bourbon Democrat Alton Parker and won a second term as U.S. President.
