19th on 21 interesting Facts About the U.S.A: Christmas was illegal in the U.S. until 1836 as it was considered an Ancient Pagan Holiday.
Christmas was originally pagan festival, you might not have known that in the UK it was made illegal for 12 years and in the US it was illegal for 260 years.
In England, parliament banned Christmas for 12 years from 1647 under Cromwell. That ban was lifted only for it to be imposed in the Massachusetts Bay Colony in 1660. This ban on Christmas, becoming law in many places, lasted until the apparently progressive state of Alabama was the first US state to legalise Christmas in 1836, meaning there was almost 200 years during which it was criminal to celebrate Christmas in the US. Oklahoma became the very last state to make Christmas legal again in 1907 despite the US making it a federal holiday in 1870.
