In many countries people celebrate at this time of year. It’s when plants start growing again and animals mate and procreate. The Saxons believed in a goddess named "Eastre" and they celebrated her at this time because she was the goddess of fertility. Hares and rabbits were considered sacred to Eastre because they are notoriously fertile animals.
Christian missionaries tried to convert northern European tribes to Christianity. To help make Christianity more attractive they turned the Saxon’s and many other people’s spring celebration into a Christian holiday. The holiday, celebrating the resurrection of Christ was also close to the Eastre celebration. That’s how our current Easter celebration evolved to include the Easter bunny.
