The 21st President of the United States was Chester A Arthur- he was president between 1881 and 1885. Prior to becoming president, he was the 20th Vice President, and he chose not to have a Vice President during his term. He became president after James A Garfield died. Prior to 1854, he was part of the Whig Party. However, from 1854 until his death in 1886, he was a republican. He was born on the 5th October 1829 and died on 18th November 1886- at the age of 57. Hope this helps :)
