what did ulysses s grant do as president

Ulysses S. Grant served as the 18th President of the United States from 1869 to 1877. As president, he played a significant role in enforcing civil rights for African Americans during the Reconstruction era. He used federal power to suppress the Ku Klux Klan, supported the 14th and 15th Amendments granting citizenship and voting rights to Black Americans, and prosecuted those who violated these rights. Grant also established the Department of Justice and created the first Civil Service Commission to combat corruption and promote reform. Despite his good intentions, his administration was marred by several scandals. Additionally, Grant signed the law establishing Yellowstone National Park, the first national park in the world, and his administration worked on settling claims against Britain peacefully and addressing Native American policies. His presidency helped restore the Union and protect civil rights more vigorously than other 19th-century presidents.
