The Easter Sunday the Vikings Came for Paris

On the morning of Easter Sunday, March 28, in the year 845, the people of Paris looked out at the Seine and saw the sails.

One hundred and twenty longships — carrying, by the chroniclers' count, five or six thousand Norsemen — had rowed and sailed up the river from the sea, past Rouen, deep into the heart of the Frankish kingdom. At their head, according to legend, sailed Ragnar Lodbrok, the semi-mythical Viking chieftain whose name would echo through sagas for a thousand years. No single surviving document proves he was really there — but someone was, and the terror was real enough.

The king of the Franks, Charles the Bald, had tried to stop them. He divided his army, stationing troops on both banks of the Seine to block the fleet's passage. It did no good. The Vikings, battle-hardened and disciplined, smashed through the Frankish forces. One account claims they captured 111 Frankish soldiers and executed them in full view of the king's army — a deliberate act of psychological warfare.

With the army broken, there was nothing between the Norsemen and Paris. They entered the city on that Easter Sunday and sacked it, looting churches and homes. But the Vikings were not finished with the Franks.

Then fortune, of a sort, intervened. Disease — described by the chroniclers as a plague, likely dysentery — broke out among the Viking camp. Weakened and eager to leave with their loot, the Norsemen agreed to withdraw. But they did not leave empty-handed, and they did not leave for free. Charles the Bald paid them an enormous ransom: seven thousand pounds of silver, weighed out in French livres, to persuade them to sail away and leave his kingdom in peace.

It was a fateful payment. The ransom of 845 set a precedent that would haunt Europe for generations: the Danegeld, the practice of paying Vikings tribute to prevent attack. The Norsemen had learned that Frankish silver could be had not only by the sword, but by the threat of the sword — and they would be back, again and again, each time demanding more.

Paris itself would face an even greater trial four decades later, when Viking fleets besieged the city for nearly a year. But the city survived that siege, and the memory of 845 survived with it — the Easter Sunday when the dragon ships came up the Seine, and a king learned that sometimes the price of peace is counted in silver.

Whether Ragnar Lodbrok truly stood at the prow that day, we will never know for certain. The sagas say yes; the history books hedge. But the 120 ships were real, the 7,000 pounds of silver were real, and the lesson Europe learned was real, too: the Viking Age had arrived at the very gates of Paris, and nothing would ever quite be the same.
