For more than eighteen years, the Royal Chancellery followed King Charles and his staff wherever they went. During the Great Northern War, the Field Chancellery was not only responsible for the archives and for contacts with foreign envoys and foreign powers, but it was assigned a number of special tasks. It functioned as a foreign ministry in the field with expanded powers. This became even more evident after the Battle of Poltava, when it was in the Ottoman Empire. In Bender, where the Swedes and their allies had retreated, new international treaties were drawn up. The famous Bender Constitution was written there and ratified by Charles XII in a royal proclamation. In it, the King and the hetman Philip Orlik promised to fight for an 'independent state' and the 'freedoms and rights of the Ukrainian people'. In addition to the huge losses in terms of human suffering caused by the war, many material assets were destroyed, as well as countless piles of irreplaceable documentation and correspondence. After arriving in Bender in 1709, diplomats, field clerks and bookkeepers had to establish new field archives. Through recently completed archaeological analyses of the soil particles left on the field office documents and the results of careful studies of primary sources, we can now recreate the history of our common cultural heritage. The studies contribute to the understanding of the early modern state formation in both Sweden and Ukraine. Funding is sought to write two articles on the extensive results of the studies.
