Linguapax emerged from a UNESCO experts meeting in 1987 which was followed up by a series of workshops and international meetings focused on the promotion of multilingual education. In the year 2001, coinciding with a growing awareness of the loss of the world's linguistic heritage, the UNESCO Center of Catalonia decided to continue the project, to give it an own structure and establish its headquarters in Barcelona.
On 21st February 2006, on the occasion of the celebration of the International Mother Language Day, Linguapax officially established the International Network by signing a framework agreement that establishes the terms of collaboration for the different delegations.
The representatives of each delegation agree on uniting their forces in order to promote the ideals of Linguapax by the means of projects concerning the revitalization and documentation of threatened languages, the investigation on intercultural and multilingual education, the formation of teachers and the elaboration of teaching materials about non-dominating languages and cultures. The headquarters of Linguapax in Barcelona is coordinating and supervising the international network in function of its necessities and possibilities and the priorities of the delegations.
