The invaders will be paid a literal king’s ransom to leave Paris.The Siege of Paris and the Sack of Paris of 845 was the culmination of a Viking invasion of the kingdom of the West Franks. The Viking forces were led by a Norse chieftain named “Reginherus”, or Ragnar, who traditionally has been identified with the legendary saga character Ragnar Lodbrok. Ragnar’s fleet of 120 Viking ships, carrying thousands of men, entered the Seine in March and proceeded to sail up the river. The West Frankish king Charles the Bald assembled a smaller army in response, but as the Vikings defeated one division, comprising half of the army, the remaining forces retreated. The Vikings reached Paris at the end of the month, during Easter. After plundering and occupying the city, the Vikings finally withdrew after receiving a ransom payment of 7,000 French livres of silver and gold from Charles the Bald. wiki/Siege_of_Paris_(845)(1776) First Europeans settle in San Francisco With 247 colonists in tow, Spanish explorer Juan Bautista de Anza founds a fort, or ‘presidio,’ on a wide bay in northern California.
