The Origin of

the Twelve Days of Christmas

Catholics in England during the period 1558 to 1829, were prohibited from ANY practice of their faith by law - private OR public. It was a crime to be a Catholic.

"The Twelve Days of Christmas" was written in England as one of the "catechism songs" to help young Catholics learn the tenets of their faith.

Alright, so onto the song - (extracted from)
The "true love" mentioned in the song doesn't refer to an earthly suitor, it refers to God Himself. The "me" who receives the presents refers to every baptized person. The partridge in a pear tree is Jesus Christ, the Son of God. In the song, Christ is symbolically presented as a mother partridge which feigns injury to decoy predators from her helpless nestlings, much in memory of the expression of Christ's sadness over the fate of Jerusalem: "Jerusalem! Jerusalem! How often would I have sheltered thee under my wings, as a hen does her chicks, but thou wouldst not have it so..."
