Social pedagogy in Bulgaria has a long and interesting tradition that has remained hidden from the international world of the subject. In Bulgaria, social pedagogy is a unique mixture of the German social pedagogical tradition, the Bulgarian pedagogical system and Russian pedagogical influence. Social pedagogy affirmed its position within the Bulgarian pedagogical space around the same time as Karl Mager used the term for the first time. In spite of the tight grip social pedagogy had on the Bulgarian education system, during the time of communism it was branded as ‘bourgeois science’ and was forbidden, but not forgotten. The second phase of the development of Bulgarian social pedagogy started at the beginning of the 1990s, as a result of the democratisation and liberalisation changes that took place following the fall of communism. Since that time, social pedagogy in the Bulgarian context has evolved into the remarkable science and practical field it is today. This article attempts to spread the knowledge of Bulgarian social pedagogy’s origins, traditions, concepts, theories and practices, and to open the door for further cooperation between Bulgaria and the international social pedagogical community.
