in this tutorial. you control the kingdom of Ludwig German in wars against other nations: When the elder Louis died in 840 and Lothair claimed the whole Empire, Louis allied with the half-brother, Charles the Bald, and defeated Lothair and their nephew Pepin II of Aquitaine, son of Pepin, at the Battle of Fontenay in June 841. In June 842, the three brothers met on an island in the Saône to negotiate a peace, and each appointed forty representatives to arrange the boundaries of their respective kingdoms. This developed into the Treaty of Verdun, concluded in August 843, by which Louis received the bulk of the lands lying east of the Rhine (Eastern Francia), together with a district around Speyer, Worms, and Mainz, on the left bank of the river. His territories included Bavaria (where he made Regensburg the centre of his government), Thuringia, Franconia, and Saxony. He may truly be called the founder of the German kingdom, though his attempts to maintain the unity of the Empire proved futile. Having in 842 crushed the Stellinga rising in Saxony, he compelled the Obotrites to own his authority, and undertook campaigns against the Bohemians, Moravians, and other tribes, but was not very successful in freeing his shores from the ravages of the Vikings.
