Why did Easter start?

Easter, named after the Goddess of the Dawn, was started to celebrate the coming of Spring. When Christianity was brought to Britain, as the Venerable Bede wrote in 731 AD, the people "kept the old festival in the gladness of a new solemnity." We kept the old name, too. Most Christians call Easter "Passover," that is they use a Word like Pâques in French, Pascua in Spanish or Pascha in Greek, derived from the Aramaic Word pascha.
