From 1647 to 1660, Christmas was intended to be a day of fasting and modesty. During the time, the Christmas celebration was unconstitutional.
The Puritan-led English Parliament in 1647 intended Christmas Day to be a day of fasting and modesty, but otherwise, it would be a regular working day, but not a feast or a holy day. The English Puritan Republic banned both religious and secular celebrations of Christmas. Shops had to stay open, public drinks and seasonal celebrations were illegal and thin cookies were taken off. Also, foliage put up as decoration was forbidden. During this time, Christmas was unconstitutional.
The ban remained in effect until the monarchy was restored in 1660.
