1912 - In the old Padre Faura Campus (now UP Manila), the University of the Philippines Military Training was born. It was made as a mandatory requirement for all male students in all departments, institutions and colleges. During the early years, the training was only within an infantry and only concentrated with the use of rifles.

The organized military training of the university was under the instruction of the Philippine Constabulary (presently known as the Philippine National Police) and Captain Silvino Gallardo was given the position as the first Commandant of Cadets.

Then the need for national defense became more acute and the US government authorized the Philippine National Guard (PNG) to be organized, similar to the National guards in US. The PNG then took over military form UP students from the Phil. Constabulary, supported by the Philippine Division of the US Army with Cap. Juan Villasanta as Commandant of Cadets.

1916 - Military training started in ULPB (formerly known as the University of Philippines College of Agriculture).

October 10, 1917 - Probably the most memorable moment in the history of the UP cadets, students and faculty members in the Manila campus and in Los Baños, Laguna, volunteered for service in World War I.

This is why, to this day, this event is being observed as "Loyalty Day" especially in Los Baños where the most colorful activities are staged. It is also the day when alumni come back to the college compound to participate in the merrymaking.
