The Danish incursions into Francia started in n 820 CE, thirteen Viking ships reached the shore in Francia, the site of the first Viking raid. In 876 Rollo invaded Normandy and started attacking all around France. He pillaged, looted, raped, and caused destruction against France and her people. Many were slaughtered and this led King Charles the Simple to send an army to oppose Rollo. The two forces fought and eventually Rollo was defeated. This defeat was at the fort of Chartres. After years of raiding and making himself wealthy he became a powerful foe against the King of France. Charles the simple created a treaty that would bring peace to France. It also gave Rollo a large swath of land. These long-term conflicts were all across Frankia and many of its towns and villages were massacred
