RMC is now over one hundred years old. It was founded in 1874 when the Dominion Government , led by Alexander Mackenzie, passed an act in Parliament to establish a military college "for the purpose of providing a complete education in all branches of military tactics, fortification, engineering, and general scientific knowledge in subjects connected with and necessary to thorough knowledge of the military profession." On June 1, 1876, the Military College of Canada opened its doors to the first class of eighteen gentlemen cadets. These are the "Old Eighteen," known by name to all cadets today. Two years later, in 1878, Her Majesty, Queen Victoria, granted the College the right to use the prefix "Royal."
"The Royal Military College of Canada Degrees Act, 1959," passed by the 25th Ontario Legislature and given Royal Assent on March 26, 1959, empowers the College to confer degrees in Arts, Science, and Engineering. RMC now offers a wide variety of programmes in these three areas, at both the undergraduate and graduate levels offered both on site through traditional studies and by distance learning through the Division of Continuing Studies.
The graduates of RMC have established a reputation of service and achievement throughout the world out of all proportion to their numbers. From the North West Campaign of 1885, through the South African War, the First and Second World Wars, Korea, the Persian Gulf, to the latest peace keeping operations the graduates of RMC have distinguished themselves in all aspects of Canadian military service. Ex-cadets have been similarly prominent in a wide variety of civilian professions.
