Fort Lewis was originally established in 1917 with the passage of a Pierce County bond measure to purchase 70,000 acres (280 km2) of land to donate to the federal government for permanent use as a military installation. A portion of the initial land was taken from the Nisqually tribe's reservation.
In early 1801, Lewis was appointed by President Jefferson to be his personal secretary. Lewis was a childhood protege of Jeffersonâs, and they renewed their bond years later while Lewis was on army duty in Charlottesville, Virginia. There is no doubt that part of Jeffersonâs reason for appointing Lewis to this position was political; like Jefferson, Lewis was a firm Republican.
