It is an intellectual trend founded by the German Karl Krause and whose doctrine was based on defending unity with opposites and trying to maintain harmony with what already exists, this thought also defended the idea that people should not depend on any type of organization or the State in order to survive. Krausism had a great boom in Spain, reaching a great development there thanks to the contributions of Julián Sanz del Río and Federico Castro.
In the 1960s, a series of Spanish intellectual characters began to study the work of a current of German ideology that was based on the philosophical thoughts of Immanuel Kant. Said ideologyhe proposed a kind of new man, without dogmas to bind him and with a pantheistic spirit. Its most important representative was Karl Christian Friedrich Krause, his written works were translated into Spanish by Julián Sanz del Río. It was from then on that Krause's thought began to invade the environments of the universities of Madrid and what was known as Krausism spread rapidly. Later Francisco Giner de los Ríos was in charge of Krause's postulates and the organization in which he was the leader (Institución Libre de Enseñanza), becoming the main representative of the Krause movement.
This movement in Spain supposed the innovation of thought. Instilling humanism and an attitude of tolerance in the ideological area in connection with free thought. One of the most outstanding characteristics of this movement was secularism, in which there was also the desire for a new education, which is why a more open educational system was proposed (greater importance was given to experiments, field investigations and an education that was detached from the religious spirit of the time). Achieving that man vindicates himself, acting with facts that mean an improvement for society in general.
This ideology had a large number of followers in the educational area, however it also had to face harsh criticism from the most conservative societies, since it was accused of abhorring traditional forms of teaching, of going against God and to impart a socialist ideology. After the civil war of 1936, the vast majority of its members withdrew to different Latin American countries mainly for political reasons.
