One of the key initiatives of Spanish anarcosindicalism was the extension of an alternative culture to the official one, which can be described as the most important culture of the 20th century in Spain of a worker organisation. In the field of education, the proliferation of anarchist rationalist schools aimed to achieve freedom of conscience in order to achieve a more humane society inspired by the natural order. This working culture, an alternative to the Burgundy, developed many ideas of great current relevance compared to what we know as unique contemporary thinking. Popular atrenos, Republican centres and village houses were born, which helped to create a critical and analytical opinion.
