The cultural dividing line between the majority society and the population with immigration and refugee experience can be found in many cultures. Different worlds collide at home, at school, among friends or in sports clubs. The young people grow up in an everyday life shaped by at least two cultures, which makes a clear definition of their cultural identity difficult. It is hard for them to clearly define their cultural identity, which makes it difficult for them to explain it to their environment. In the reality these issues often dominate: Integration and adjustment problems at school or at work, unemployment and poverty, and the experience of racism and exclusion. Without "cultural identity" and without the recognition of cultural potential, active participation in cultural and social life is difficult. There is a lack of models for developing and communicating "cultural identity" and the meaning of "cultural diversity" that are not primarily conflictual and represent a viable perspective for young people. This problem does not only affect young people who are socialised religiously or denominationally differently from the host society, but also young people whose parents come from Southeast Europe and the Middle East and whose cultural characteristics are often interpreted as foreign or at least alien and often cause exclusion. On the other hand, young people from the majority of society hardly deal with questions of cultural identity. Obvious things like a headscarf, the renunciation of pork, festivals, visiting mosques or clothing habits are only perceived on the surface, often without background knowledge. Causes of migration such as disasters, poverty, war and persecution are also persecution are rarely a topic in their lives. In this context, the culture of the countries of origin usually seems even more distant. Integration on the one hand and the imparting of cultural knowledge regarding the countries of origin on the other hand, can only succeed if the process of "becoming aware" of cultural diversity and identity is promoted. Mutual understanding of the culture behind the stereotypes is promoted and accompanied from an early age. Immigration has increased greatly in recent years, and this is reflected in the youth culture projects. Especially in the last project "Timeless" of our organisation on the topic of anti-Semitism, 30 young people participated, including 10 German youths with and 7 without an immigrant background and 13 participants who have been in Germany for 1-5 years in Germany. The objectives of our project are the following: 1. The young people with and without an immigration and refugee history and refugee backgrounds approach their culture with the method of biographical work and present this during a joint presentation. 2. The young people learn about similarities and differences with the aim of learning about the causes of migration as well as understanding and appreciating cultural diversity with all its potentials and possibilities for the further development of a society. 3. In various workshops, the groups deal with their own and each other's cultural identities and learn what these have to do with them and their lives and what resources and competences a common social development can offer. 4. The project also aimed to build bridges for young people with immigration and refugee backgrounds and young people with and without special needs, build bridges for a common European consensus of values and impart cultural competences. Agreement on common values is a pillar of common cultural and thus social identity.
