Until a decade, krausism not withstanding it german root—again and again recalled by its originator, Julián Sanz del Río— was considered a cultural phenomen almost exclusively spanish, developed between the second half of 191 century and the end of Civil War of the 20'th century, wich had also an effective influence in Latin America. The discovery by the spanish searcher Enrique Méndez Ureña S.J. of a series of articles by Karl C.F. Krause, published in 1811 has shown connections (much more profund that those up to now known) between the german Krause's disciples and the spanish ones. The author offers an overview of the developement of krausian studies, their differnt nuances and relationships. Finally he opens a new chapter in the research of the influence of krausism in Colombia concretely in the educacional project of Gimnasio Moderno, showing the conection between this important high school and the Institución Libre de Enseñanza, core of spanish krausism.
