Scouts Royale Brotherhood was originally formed and conceptualized as an organization among high school students. It was founded by the members of the Alpha Delta chapter of Alpha Phi Omega-Philippines : Lord Len Toledo, Lord Bong Manuel,Lord Jun Cristobal, Lord Vic Tomelden, and Lord Cary Lazo as the National Adviser,with the purpose of expanding APO's principles of Leadership, Friendship & Service, and Scouting in the intermediate students. It was founded on September 22, 1975 at San Sebastian College with 37 chartered members. Bro. Vicente "Bing" Marabut (+) was declared the "EL DULCE" or "the leader."
From being a fraternity exclusively for high school students, SRB evolved and developed into an independent (inter)national service fraternity catering to both high school and college students. While it evolved to be an independent and separate entity to that of Alpha Phi Omega (APO), SRB is a consistent ally and friend of all APO brothers united by a common and undeniable fraternal bloodline as well as optimum principles such as developing effective and democratic leadership, fostering friendship and rendering service to all.
