United States Army
American soldiers during the Korean War.
Between 1789 and 1808, the size of the regular United States Army fluctuated significantly, driven by the perceived immediacy of frontier and foreign threats. When George Washington was inaugurated in 1789, the force consisted of only 595 men organized into a single regiment.1
As tensions with Native Americans and foreign powers rose, Congress authorized periodic expansions and reductions of the force:1
- 1791: Expanded to 3 regiments.1
- 1792: Increased to 5 regiments following Saint Clair’s Defeat.1
- 1798: Grew to 9 regiments during the XYZ Affair and the Quasi-War with France.1
- 1800: Reduced to 6 regiments.1
- 1802: Further reduced to 3 regiments.1
- 1808: Increased to 11 regiments.1
These shifts reflected the young nation's ongoing struggle to balance the need for a standing military nucleus with political concerns regarding federal power and the reliance on a militia system.1
