The history of Texas A&M University, the first public institution of higher education in Texas, began in 1871, when the Agricultural and Mechanical College of Texas was established as a land-grant college by the Texas Legislature. For much of its first century, enrollment at Texas A&M was restricted to men who were willing to participate in the Corps of Cadets and receive military training. During this time, a limited number of women were allowed to attend classes but forbidden from gaining a degree. During World War I, 49% of A&M graduates were in military service, and in 1918, the senior class was mustered into military service to fight in France. During World War II, Texas A&M produced over 20,000 combat troops, contributing more officers than both the United States Military Academy and United States Naval Academy combined.
