In this article, we offer a socio-historic overview of the development of social work and social pedagogy in Mexico. First, we examine the rise of the welfare state in Mexico in the immediate post-revolution period and the way the new secular government assumed control of social intervention. We describe the inception of the School of Social Assistance and the emergence of social work in the country, as well as exploring the role and influence of Cultural Missions and the training of social workers. We discuss the role of Fundamental Education, rural schools and their resemblance to the ideals of social pedagogy. Finally, we describe the founding of the Degree in Educational Intervention, which we consider sows the seeds of socio-pedagogical thought and practice in Mexico. We conclude that, despite the many periods of reorganisation of social intervention by successive governments, different initiatives use education to promote individual and collective development. Though social pedagogy does not exist as a profession in Mexico and social work is an imprecisely defined profession, education has a socialising potential that underpins pedagogical work of an extensive network of areas and agents animated by social ideals and goals.
