When was the first 5 star general appointed in the Army?

The first five-star general in the United States Army was General Dwight D. Eisenhower, who was appointed to this rank in December 1944. This appointment occurred during World War II, a critical period in which the United States was heavily involved in military operations in Europe. The establishment of the five-star rank was introduced to provide a unified command structure among the Allied forces and to acknowledge leaders of significant stature who were managing vast operations. Eisenhower's leadership and strategic vision were indispensable to the success of the Allied forces in the European theater, making his appointment fitting as the war approached its conclusion.
