In October 1883, the Boys' Brigade was founded in Glasgow, Scotland, by Sir William Smith, a Presbyterian Church leader who was deeply concerned about the moral and physical well-being of young boys in urban settings. The inaugural meeting was held at North Woodside Church, where the vision for the Brigade was articulated: to create a framework that would instill discipline, responsibility, and a sense of Christian duty in youth. This innovative idea emerged in a period where many boys faced limited opportunities, and often, a dangerous environment in urban industrialized areas. Smith’s initiative aimed to redirect this energy in constructive ways through organized activities, encouraging boys to engage in values-based leadership and community service.

The Boys' Brigade quickly adopted a military-style structure, including ranks and formations, which appealed to many families seeking to instill discipline in their sons. The early curriculum included drill practice, games, and spiritual instruction, making it distinct from other youth organizations of the time, which lacked a strong moral foundation. This multifaceted approach helped to foster teamwork and community among the boys, and even led to the development of camps and competitions to further enhance their experiences.

As the organization grew rapidly, it expanded beyond Scotland into other parts of the United Kingdom and eventually internationally. The Brigade pioneered many youth engagement strategies that are still in use today by various youth organizations. Over the decades, it has adapted to changing social contexts, embracing inclusivity and broadening its mission to serve a diverse range of youth. The founding meeting was pivotal in shaping the future of youth associations, establishing a precedent for combining moral instruction with physical activity.
