In the beginning, Saxony ruled the Empire, as the Ottonian dynasty made it her capital region. Saxony today is a diverse land focused on the families that emerged from the collapse of the Saxon tribal duchy in the early Middle Ages. In the north, the remnants of the Welf fought over their Ottonian legacy. In the East, the Saxons started their colonization of Slavic lands. In the South, the Wettin dynasty squabbled over inheritance but eventually built a nation that could challenge the Emperor.
