"Viking Age Relevance
After the battle of Thiméon in 881, the Vikings continue to raid and sack towns in Francia. Louis the Younger (aka Ludwig of Saxony), king of the East Franks, has defeated the Vikings at Thiméon.1 Meanwhile, he is busy invading West Francia after the death of Louis the Stammerer. But the West Frankish nobles choose The Stammerer’s son, Louis III, to succeed him and immediately start negotiations with Ludwig that result in the Treaty of Ribémont in 880. In the end, Ludwig receives Lotharingia and withdraws his forces from West Francia.2

With the treaty settled, Louis III then agrees to share the West Frankish kingdom as joint king with his brother Carloman. Their first task is to deal with the rebel duke Boso who has just declared himself king of the Provence. Their campaign fails and their siege of Vienna is unsuccessful.3 Louis returns to northern Francia in 881, to stop the Vikings who are still raiding West Frankish towns and monasteries. Still only a young man of not yet eighteen, Louis finds the Vikings and defeats them at Saucourt.4"
