Trinity College is a constituent college of the University of Cambridge in England. With around 600 undergraduates, 300 graduates, and over 180 fellows, it is the largest college in either of the Oxbridge universities by number of undergraduates. By combined student numbers, it is second to Homerton College, Cambridge. In 1848, Trinity hosted the meeting at which Cambridge undergraduates representing private schools such as Westminster drew up the first formal rules of football, known as the Cambridge Rules.
