Long before Christianity made its way to the native Germanic peoples, Norwegians celebrated the winter solstice by brewing and drinking beer to honor their Norse gods. To celebrate “Jul,” a Norwegian word that in modern vernacular refers to the Christmas season, Vikings brewed and consumed strong, barley-based beer while in the throes of winter’s coldest and dreariest months. They also used the ale to make offerings in hopes to entice the gods to bring back the summer sun.
According to “The Geography of Beer,” King Haakon the Good, who ruled from 934 to 961, later used the ancient Jul celebration to push a Christian agenda. As part of his efforts to introduce Christianity to the Norwegian people, King Haakon the Good implemented a pagan-meets-Christian mash-up, making it a law to celebrate Christmas with beer. Those who didn’t have beer at their Christmas feast were issued a fine. Norway became Christianized in the 11th century.
Many Christmas traditions come from the Roman holiday Saturnalia. During Saturnalia, work and business came to a halt. Schools and courts of law closed, and the normal social patterns were suspended.
People decorated their homes with wreaths and other greenery, and shed their traditional togas in favor of colorful clothes known as synthesis. Even slaves did not have to work during Saturnalia, but were allowed to participate in the festivities; in some cases, they sat at the head of the table while their masters served them.
Instead of working, Romans spent Saturnalia gambling, singing, playing music, feasting, socializing and giving each other gifts. Wax taper candles called cerei were common gifts during Saturnalia, to signify light returning after the solstice.
