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 Reconstruction-era Texas Legislature. Classes began on October 4, 1876. Although Texas A&M was originally scheduled to be established under the Texas Constitution as a branch of the yet-to-be-created University of Texas, subsequent acts of the Texas Legislature never gave the university any authority over Texas A&M. In 1875, the Legislature separated the administrations of A&M and the University of Texas, which still existed only on paper. 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. Shortly after World War II, the Texas Legislature redefined Texas A&M as a university and the flagship school of the Texas A&M University System, making official the school's status as a clear and separate institution from the University of Texas. In the 1960s, the state legislature renamed the school Texas A&M University, with the "A&M" becoming purely symbolic. Under the leadership of James Earl Rudder, the school became racially integrated and coeducational. Membership in the Corps of Cadets became voluntary. In the second half of the 20th century, the university was recognized for its research with the designations sea-grant university and space-grant university. The school was further honored in 1997 with the establishment of the George Bush Presidential Library on the western edge of the campus. Early years The United States Congress laid the groundwork for the establishment of Texas A&M with their proposal of the Morrill Act. The Morrill Act, signed into law July 2, 1862, was created to enable states to establish colleges where the "leading object shall be, without excluding other scientific and classical studies and including military tactics, to teach such branches of learning as are related to agriculture and mechanical arts ... in order
