This youth exchange "Time Travellers III: Biking through History" was a youth exchange for youth in which they explored the history of Western Pommerania in Northeast Germany (along the border of Poland). In this exchange participants learned about the history of the region, which is remarkable in its origins as Germania Slavica, region which was until the 13th century mainly populated by Slavic tribes (so called Wends). Here originated the House of Griffins and became part of the feudal association of the German Empire. This region has also a distinct history of viking conquest, two centuries of Danish rule and a rich history of cities in the Hanse Union. With the history of WWII, its division with a part in Poland and another in the GDR this regions offers an enormous cross over of culture that ridicule nationalistic concepts. We invited to this exchange our young friends from Poland, Czechia, Bosnia and Romania together with their German partners, which took a special interest in this example of mutual history. The Slavic element in the German state nowadays is overlooked and many Germans are not aaware that their origins are those of authochton Slavic population. The results of WWII has erased the memories of millions of German who lived together with Slavic (and Romanian) peoples throughout Eastern Europe in peaceful coexistence. It is important to revive these memories, also when they end up in a terrible nightmare of conquest, slaughter, destruction and expulsion. The Slavic nations are the immediate neighbours of Germany, Germany itself the leading point of immigration for them. Deeper relations can only found on a clear view of historical reality and not nationalistic wish thinking. This exchange contributed to this effort and contributed to reconciliation, friendship and cooperation in the future in the field of remembrance of common Slavic-German history. The objective was to travel with bikes and tents from Neustrelitz to Heringsdorf and to explore the divided island of Usedom/Uznam, which is now united in the European Union. During this travel we dealt with several aspects of active remembrance work and with the topic of volunteer involvement in such activities.
