Greece was home of the Ancient Olympic Games, and was therefore a natural choice as host nation for the revival of the modern Olympic Games in 1896. The nation has competed at every Summer Olympic Games since then, one of only four countries to have done so (and the only one of them to compete under its national flag at Moscow despite the Greek government's support for an American-led boycott of the Games over the Soviet invasion of Afghanistan), and most Winter Olympic Games since 1936. During the Parade of Nations at the Opening Ceremony, Greece is always called first, due to its status as being the founder of the ancient precursor to the modern Olympic Games.
