The Viking raids on Paris in the 9th century are some of the most notorious episodes in the history of the Norse invasions of Europe. Led by notable leaders such as Ragnar Lothbrok and his sons, including Ivar the Boneless, the Vikings targeted Paris due to its wealth and strategic importance as a trade hub. The first major raid occurred in 845 AD when a fleet of around 120 ships, commanded by Ragnar, laid siege to the city, demanding a ransom that ultimately amounted to a significant sum of silver and gold. This successful raid highlighted the vulnerabilities of Frankish defenses and prompted King Charles the Bald to negotiate with the Viking leader. Subsequent raids followed, with the most significant assault occurring in 885-886 AD when a large Viking force besieged Paris for nearly a year, facing fierce resistance from its defenders, led by Count Odo. The siege ended with a negotiated settlement that allowed the Vikings to retreat with plunder, demonstrating both the power and persistence of these Norse invaders. The raids had lasting implications for Paris and the surrounding region, leading to the establishment of fortified defenses and influencing the political landscape of medieval France. These events contributed to the perception of Vikings as formidable raiders and explorers, and they remain a critical chapter in the complex history of Norse interactions with European societies.
