On this day in 1797, Mason William Blount was the first Senator to be expelled by impeachment of the United States Senate. An aggressive land speculator, Blount gradually acquired millions of acres in Tennessee and the trans-Appalachian west. His risky land investments left him in debt, and in the 1790s, he conspired with England to seize the Spanish-controlled Louisiana Territory in hopes of boosting western land prices. When the conspiracy was uncovered in 1797, he was expelled from the Senate, and became the first U.S. public official to face impeachment. Blount nevertheless remained popular in Tennessee, and served in the state senate during the last years of his life.

William (Willie) Blount was born on Easter Sunday, March 26, 1749 in Windsor, North Carolina. He served as the territorial governor of Tennessee, from 1790 until 1796 and as the Governor of the State of Tennessee from 1809 until 1815. He was a member of Unanimity Lodge No. 54 in North Carolina.
