"Migration is an old process introducing cultural differences which is not new for Europe and partly explains its complex territory and cultural diversity that the refugee crisis of 2015 has reinforced through its massive waves of immigration. Consequently, there is an increasing number of migrants in our schools, bringing a huger diversity in school communities and classes. We are living in a world in motion with growing flows of migrants induced by several reasons which makes it a necessity to learn adaptability, tolerance and open-mindedness. Europe sees its construction endangered and weakened as we can witness the rise of nationalist and xenophobic movements in an increasing number of European countries at levels that have not been reached since the 1930s, we see a growing communitarism, individualism and selfishness together with a lack of intercultural understanding.Our schools from France, Spain, Finland, Greece, Czech Republic and Poland present a diversity of geographical, economic and social situations but have one common feature: a strong history of immigration in their countries. Each country has a specific history towards migration which brings a general overview of the present time situation in Europe through varied prisms :- The Mediterranean countries that are on first line facing mass migration from Africa and the Middle East, are in a difficult economic situation: Greece and Spain where meetings with newly arrived Syrian, Kurdish, Iraqi and Pakistanese teenager migrants and with young adults from South America were made possible.- The Nordic and Eastern Europe countries whose history is rooted in migration mainly in neighbouring countries and for whom Southern migrations represent a new concern: Finland, Czech Republic, Poland- Other countries have a long tradition of emigration and immigration both with colonial empires and neighbouring countries: France which has a particular policy which aims at assimilating migrants, Greece and Spain also match this profile.We aimed at working for a more efficient social inclusion in our schools, as school is one of the main actor of the social link and intercultural understanding among people. We also noticed that the young people of today are in search of an identity, should it be individual, collective or both? Is the European feeling strong enough for our youth to face the challenges the 21st century has in store?The participants had to take into account different kinds of situations, which allowed them to enlarge their perception of contexts and to have a global perspective beyond national borders. This partnership aimed at facing a topical challenge: breaking stereotypes and enlarging the participants' visions on the present world issues of migrations . We aimed at deepening the notion of migration and promoting the values of understanding, collaboration and tolerance. We targeted to raise awareness of the richness of cultural diversity and to promote intercultural understanding, to make participants aware of human rights. Strenghtening European citizenship and social responsibility was at the core of the project by developping social entrepreneurship among teens and encouraging the feeling of social responsibility. One of our main goal was to reinforce social inclusion, via intercultural understanding inside and outside schools: we aimed at creating a more inclusive school atmosphere, hence allowing migrant populations or people from different horizons not to feel marginalized in schools. By enhancing intercultural understanding , we aimed at fighting school drop out and at placing school as a space of inclusion, not only of academic teaching.To fulfill our objectives, we were assisted by the NGO ""Terre des Hommes"". We worked with EU institutions and the ESN who brought their expertise and supported the participants (105 students and 20 teachers) along our collaboration. We met politicians, social workers, migrants and organised actions of solidarity.The 3 final outcomes were elaborated through eTwinning constant collaboration and made concrete during the meetings in the 6 countries.Our cooperation resulted in 3 outcomes:- the ""IWE Charter of the migrant of the 21st in Europe""- the app ""IWE 21st centuty migrant's toolkit""- the awareness video campaign ""IWE for intercultural understanding""We presented them during a final online event in February 2021 attended by one hundred people including students, teachers, parents, headmasters, a EU MEP and French education board representatives. This partnership aimed at paving the way to an opening of schools to societal issues and to stress the part played by school as an actor of social inclusion. We integrated non academic issues to school concerns and enhanced the development of European citizenship built up via school projects. We think we succeed in pushing the walls of school and minds which was at the core of the project by promoting social entrepreneurship in the schools communities."
