The main problem that was diagnosed by us before the start of the project was the fact that Lithuanian and Polish youth were not fully aware of the common cultural and historical heritage of our countries; nor did we know the influence of historical differences on our contemporary reality. The primary goal of our activity was the creative cooperation of young people from both countries, aimed at finding historical and contemporary elements connecting our cultures. At the same time, we wanted to develop competences in the field of discussion culture, source analysis, presenting conclusions in a transparent and attractive way, working in an atmosphere of tolerance, understanding and sympathy for each other. Together with the Lithuanian group, at the stage of planning the activities, we noticed that we perceive many common historical events in a slightly different way. In schools, not much time is spent talking about what unites us and what is different. We found it not only interesting, but also allowed us to better understand our mutual relations. Thanks to the exchange: we were able to show that our story has many common points, but we often view it differently, we were able to take actions to strengthen ties between the participants of both countries, we were able to pass on the knowledge and skills that we need not only in the field of history and culture, but also to work and function in society, participants could acquire both hard and soft skills, such as communication, negotiation, teamwork, critical thinking, visual presentation of conclusions, we had the opportunity to overcome prejudices and stereotypes in the perception of common history and in contemporary relationships, we had the opportunity to discover common roots and historical similarities that shaped our cultural identity. During the exchange, through the performative learning of history and learning from each other, we reached what is common in our culture and history, and how each country perceives the formative historical events indicated by us. Both the Polish and the Lithuanian group noticed the need to integrate and share the knowledge we have, as well as to apply non-formal education to deepen it. The exchange program enabled cultural expression, mainly through the use of the performative ways of learning about culture that allowed it to "touch" our common history.
