This year marks the 200th anniversary of when the famous Christmas carol "Silent Night" was first performed at a church in Austria.
While the lyrics were written in 1816 by a Catholic priest named Joseph Franz Mohr, it was not until two years later that Franz Xaver Gruber composed music to go with the words.
Since then, "Silent Night" has been translated into hundreds of different languages and performed by countless choirs as well as many famous musicians like Stevie Nicks, The Temptations, CeeLo and Elvis Presley.
Here are five interesting facts about the enduring Christmas carol. They include the origins of its author, its first performance in the United States, and being put on the World Heritage List.
The lyrics for "Silent Night" came from an Austrian Catholic priest named Joseph Franz Mohr, who penned the six verses as a poem while serving as an assistant priest in 1816.
While living in Oberndorf, he became good friends with Franz Xaver Gruber, a local music teacher who composed the melody for the song in 1818.
Mohr was born out of wedlock and grew up in poverty before becoming a priest. Despite the eventual success of "Silent Night," Mohr would die poor, his estate only consisting of a single guitar.
