High Quality Content by WIKIPEDIA articles! John Henninger Reagan (October 8, 1818 – March 6, 1905), was a leading 19th century American politician from the U.S. state of Texas. A Democrat, Reagan resigned from the U.S. House of Representatives when Texas seceded from the Union and joined the Confederate States of America. He served in the cabinet of Jefferson Davis as Postmaster General. After the Confederate defeat, he called for cooperation with the federal government and thus became unpopular, but returned to public office when his predictions of harsh treatment for resistance were proved correct.
