Founded in 1870 as a land-grant university and ninth university in Ohio with the Morrill Act of 1862, the university was originally known as the Ohio Agricultural and Mechanical College (Mech). The college began with a focus on training students in various agricultural and mechanical disciplines but was developed into a comprehensive university under the direction of then Governor (later, President) Rutherford B. Hayes, and in 1878 the Ohio General Assembly passed a law changing the name to "The Ohio State University". It has since grown into the third-largest university campus in the United States. Along with its main campus in Columbus, Ohio State also operates a regional campus system with regional campuses in Lima, Mansfield, Marion, Newark, and Wooster. [END]
