Abstract: The Danube and the Douro rivers are geographic objects of international importance as a result of their direct influence on the territories surrounding them. The present article attempts to make a geographic parallel on the importance of both rivers in their respective geographic locations – Southwest Europe and Southeast Europe. It explores the influence of Douro River on Northern Portugal and the Atlantic, as well as the history of the Eastern-European people who resided alongside the Danube River. Moreover, it also examines the future of the lands they occupy.
