In 1980, the Italian Grand Prix moved from the high-speed Monza circuit to Imola (later known as Autodromo Dino Ferrari), as a direct result of 1978's startline pile-up, which claimed the life of the popular Swedish driver Ronnie Peterson. It was won by Nelson Piquet for Brabham-Ford. The following year, the Italian Grand Prix returned to Monza. This left the owners of the Imola circuit without a Grand Prix. They were eager to remain on the calendar, however, and with an Italian Grand Prix already on the calendar, they asked the Automobile Club of San Marino, the motorsport authority of the nearby Republic of San Marino, to apply for their own Grand Prix. Their application was successful and the San Marino Grand Prix was born.
