The Cavalier was a great favourite of King Charles I and because of this the name King Charles Cavalier became widely used. In the 16th century aristocratic families led a very insular life and the spaniel is nearly always depicted with the children of the family. The word 'spaniel' implies that the dog originated in Spain so maybe these dogs were bought for the children of the English houses.

The breed continued to be in favour after the death of Charles I as the spaniels were held in high regard by Charles II. Wherever he went, he had a pack of them with him. It was not only the English court that kept the Cavalier, however - many of the courts overseas also had a great love of them, including Henri III of France.

The main reason for the breed's popularity in England is that they are such happy dogs and you cannot find a better companion for children.
