In 1854, Lafayette College became affiliated with the Presbyterian Church. By relinquishing their control, the College was able to collect $1000 a year from the Presbyterian Church Board of Education as regularly as the latter could pay it. In the time from 1855 to 1856, Lafayette had a peak enrollment of 112 students in total. The class of 1857, a close-knit group of 27 men, worked in secrecy to establish charters in national fraternities, thus founding the first Greek fraternities at Lafayette College. These fraternities remained secret until 1915, as they were discouraged by the authorities as divisive of group unity.
