The 1928 Games were the first true Winter Olympics, held on its own, and not in conjunction with a Summer Olympics. The preceding 1924 Winter Olympics were retroactively renamed into Winter Olympics. They were actually part of the 1924 Summer Olympics. All preceding Winter Events of the Olympic Games were the winter sports part of the schedule of the Summer Games, and not as a separate Winter Games. These games also replaced the now redundant Nordic Games, that were held quadrennially since early in the century.
The 1940WinterOlympics had originally been awarded to Japan, and were supposed to be held in Sapporo, but Japan had to give the Games back in 1938, because of the Japanese invasion of China in the Sino-Japanese War (1937-1945).
In 1952, the WinterGames came to Norway, considered to be the birthplace of modern skiing.
Winter pentathlon, a variant to the modern pentathlon, was included as a demonstration event in 1948.
