The Winter Olympic Games is a major international multi-sport event held once every four years for sports practiced on snow and ice. The first Winter Olympic Games, the 1924 Winter Olympics, were held in Chamonix, France.

The original five Winter Olympic sports (broken into nine disciplines) were bobsleigh, curling, ice hockey, Nordic skiing (consisting of the disciplines military patrol, cross-country skiing, Nordic combined, and ski jumping), and skating (consisting of the disciplines figure skating and speed skating). The Games were held every four years from 1924 to 1936, interrupted in 1940 and 1944 by World War II, and resumed in 1948.

The Winter Olympic Games have evolved since their inception. Sports and disciplines have been added and some of them, such as Alpine skiing, luge, short track speed skating, freestyle skiing, skeleton, and snowboarding, has earned a permanent spot on the Olympic program. Some others, including curling and bobsleigh, have been discontinued and later reintroduced; others have been permanently discontinued, such as military patrol, though the modern Winter Olympic sport of biathlon is descended from it.
