What was the role of ulysses s. grant in ending reconstruction

After the war, Grant led the military supervision of Reconstruction in the former Confederate states. Elected president in 1868, he stabilized the nation in a turbulent period and fought the Ku Klux Klan using the army and the newly created Justice Department, while reinforcing the Republican party in the south of the country. In the elections, Republicans won in eleven states and some African-Americans were elected to positions in the national administration, but the black minority began to be attacked in the south despite Grant's attempts to protect them. In 1871 the president founded the Civil Service Commission to appease the reformers. A year later, he won the election again by winning a coalition of Republican Democrats and Liberals. In the southern states, the Republican coalitions split and were defeated in favor of the so-called "Redeemers of the South," a white faction that resorted to violence, electoral fraud and racism. To this were added several corruption scandals that peppered members of the federal administration. Grant's Peace Policy with the Native Americans was a bold starting point but ended up being a failure.

whats the question? im not quite understanding your question.

- a government ruled by the people, or assembly. officials monarchy - a single ruler like a king. over time some city-states, like athens would change governments. what this means is that all the citizens voted on all the laws.
