English: George Washington being promoted to Major general by Continental Congress
During the Revolutionary War, the Continental Congress appointed and promoted twenty-nine officers to major general, the highest rank under Washington.[3] During the eight year war, there were four key events that caused Congress to name new major generals: the initial formation of the Continental Army, the expanding British invasion threat of 1776, the need for a professional army in 1777 and 1778, and lastly the later years of the war and the need to recognize state contributions and meritorious service. Bitter promotion controversies among the generals and Congress occurred during each of these periods.
[3]Service and promotion dates and rank are from Francis B. Heitman, Historical Register of Officers of the Continental Army During the War of the Revolution (Baltimore: Clearfield, 1982).
