The Paralympic Games or Paralympics, also known as the Games of the Paralympiad, is a periodic series of international multisport events involving athletes with a range of disabilities. There are Winter and Summer Paralympic Games, which since the 1988 Summer Olympics in Seoul, South Korea, are held almost immediately following the respective Olympic Games. All Paralympic Games are governed by the International Paralympic Committee (IPC).

The modern Olympic Games or Olympics are the leading international sporting events featuring summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games are considered the world's foremost sports competition with more than 200 teams, representing sovereign states and territories participating; by default the Games generally substitute for any World Championships the year in which they take place. The Olympic Games are held every four years; since 1994, they have been alternated between the Summer and Winter Olympics every two years during the four-year period.
