Curling was invented by the Scots way back in the early 16th century, a short 100 years after they invented golf [source: St. Andrews Links]. The winter game took advantage of two abundant Scottish natural resources: iced-over lakes and ponds (Scottish winters were even longer and colder back then), and smooth river rocks. The oldest known curling stone was dredged from the bottom of a Scottish lake and inscribed with the date 1511 [source: Weeks].
In the mid-18th century, Scottish stonecutters and farmers immigrated to North America and brought their game with them, first to Canada — where it caught on quickly with the military — and then to the U.S. [source: Canadian Curling Association]. By the mid-19th century, there were curling clubs across Canada and in northern U.S. cities like New York, Detroit and Milwaukee [source: USA Curling]. The first official rules of curling were drafted by the Grand Caledonian Curling Club in Edinburgh in 1838 [source: World Curling Federation].
From the beginning, curling was foremost a friendly, social game. Historically, alcohol and curling were inseparable. Even today, rounds of curling are customarily followed by a shared drink, although Olympic hopefuls are more likely to buy each other some Powerade than mugs of lager [source: Costa].
Curling was among the sports played at the very first Winter Olympic Games in Chamonix, France in 1924. Great Britain — which includes Scotland, of course — took home the gold in Chamonix, but curling was demoted to a demonstration sport in the Lake Placid games of 1932. After Lake Placid, curling dropped out of the Olympics altogether until it returned as a demonstration sport in the 1988 and 1992 games, and finally regained medal status for the 1998 games in Nagano [source: World Curling Federation].
Outside of the Olympics, curling champions are crowned at country-specific and international events like the World Championship tournaments held for men, women, seniors (over 50), junior divisions (under 18), Paralympic (wheelchair curling), and the newest category: mixed doubles. In mixed doubles, there are only two players per team (one man, one woman) and each end is limited to six stones per team instead of eight. Additionally, one of each team's six stones is placed in position on the ice before the rest of the stones are delivered [source: World Curling Federation].
