In 1960, Guttmann brought 400 athletes to Rome to compete in the "Parallel Olympics", which ran in parallel with the Summer Olympics and came to be known as the first Paralympics. Since then, the Paralympics have been held in every Olympic year and, starting with the 1988 Summer Games in Seoul, the host city for the Olympics has also played host to the Paralympics. The International Olympic Committee (IOC) and the International Paralympic Committee (IPC) signed an agreement in 2001 which guaranteed that host cities would be contracted to manage both the Olympic and Paralympic Games. The agreement came into effect at the 2008 Summer Games in Beijing, and at the 2010 Winter Games in Vancouver.
