Lore & Background
Rainier was born at the Prince's Palace of Monaco, the only son of Hereditary Princess Charlotte and Prince Pierre. He married American film star Grace Kelly in 1956, and they had three children: Caroline, Albert and Stéphanie. He died in April 2005 from complications of a lung infection compromised by years of cigarette smoking, and was succeeded by his son Albert II.
In Their Own Story
Rainier met Grace Kelly during a photocall at the Palace in 1955 for her Cannes Film Festival trip. After a year of courtship involving "a good deal of rational appraisal," they married on 18 April 1956 in a civil ceremony at the Palace, followed by a religious wedding on 19 April at Saint Nicholas Cathedral. Rainier wore a custom military uniform based on Napoleon Bonaparte's designs. Presided over by Bishop Gilles Barthe and broadcast by MGM Studios to over 30 million viewers globally, it was hailed as the "wedding of the century." The couple honeymooned on their yacht, Deo Juvante II. They had three children: Princess Caroline (born 23 January 1957), Prince Albert (born 14 March 1958), and Princess Stéphanie (born 1 February 1965). All were delivered at the Palace.
