"In 911, a group of Vikings led by Rollo besieged Paris and Chartres. After a victory near Chartres on 26 August, Charles decided to negotiate with Rollo, resulting in the Treaty of Saint-Clair-sur-Epte which created the Duchy of Normandy." https://en.wikipedia.org/wiki/Charles_the_Simple#King_of_West_Francia
"The treaty of Saint-Clair-sur-Epte (911) is the foundational document of the Duchy of Normandy, establishing Rollo, a Norse warlord and Viking leader, as the first Duke of Normandy in exchange for his loyalty to Charles III, the king of West Francia, following the Siege of Chartres."
"Rollo in June 911 unsuccessfully laid siege to Chartres. He was defeated in battle on 20 July 911.[1] In the aftermath of this conflict, Charles the Simple decided to negotiate a treaty with Rollo.
The talks, possibly led by Heriveus, the archbishop of Reims, resulted in the Treaty of Saint-Clair-sur-Epte in 911." https://en.wikipedia.org/wiki/Treaty_of_Saint-Clair-sur-Epte
"In a state of despair, possibly afflicted by severe depression, Louis died at Frankfurt am Main on 20 or 24 September 911, seventeen or eighteen years old." https://en.wikipedia.org/wiki/Louis_the_Child
The # 911 obviously intersects at some key moments and places in time. Life & death, destruction & violence.
