Since 1911 part of the Monte Carlo Rally has been held in the principality, originally held at the behest of Prince Albert I. Like the Grand Prix, the rally is organised by Automobile Club de Monaco. It has long been considered to be one of the toughest and most prestigious events in rallying and from 1973 to 2008 was the opening round of the World Rally Championship (WRC). From 2009 until 2011, the rally served as the opening round of the Intercontinental Rally Challenge. The rally returned to the WRC calendar in 2012 and has been held annually since. Due to Monaco's limited size, all but the ending of the rally is held on French territory.
