1. Christmas Trees
Decorated trees date back to Germany in the Middle Ages, with German and other European settlers popularizing Christmas trees in America by the early 19th century. A New York woodsman named Mark Carr is credited with opening the first U.S. Christmas tree lot in 1851.

The origins of hiding a Christmas pickle ornament are a bit murky but it’s likely it grew from a Woolworths marketing gimmick from the late 1800s, when the retailer received imported German ornaments shaped like a pickle and needed a sales pitch.

5. Boozy eggnog
Although the yuletide cocktail stems from posset, a drink made with hot curdled milk and ale or wine from medieval England, American colonists get credit for making it popular and adding rum. Even George Washington had a special recipe.
