Christmas carols are songs about Jesus and when he was born.
The earliest carols were written in the 1400s and were usually sung in people’s homes.
Christmas carols were banned by Oliver Cromwell between 1647 and 1660 because he believed Christmas should be a serious day.
Today carols are sung by carol singers who may go between houses singing or sing in the street. Carols are also sung in Church at carol services, sometimes by candlelight.
