Answer Summary
Princess Grace was married to Prince Rainier III, Sovereign Prince of Monaco. Their union, commonly known as the Grimaldi wedding, took place in April 1956 and created one of the most visible European dynasties of the twentieth century. This profile explains who Prince Rainier was, how the marriage unfolded, the roles Grace assumed, and why the partnership remains historically significant.
Prince Rainier III of Monaco: Background
Prince Rainier III was born on 31 May 1923 in Monte Carlo, Monaco. He was the only son of Prince Pierre, Duke of Valentinois, and Princess Charlotte, Duchess of Valentinois. Before inheriting the throne, he served in the French Army and reached the rank of Lieutenant. He became Sovereign Prince of Monaco in 1949 following the death of his grandfather, Prince Louis II.
Path to the Throne
Rainier’s path to sovereignty was shaped by the lack of direct heirs in the Grimaldi line. After Louis II acknowledged his daughter Charlotte and later recognized her right to succession, Rainier became the designated heir. His education, military service, and diplomatic engagements prepared him for the responsibilities of ruling a small but sovereign Mediterranean city-state.
The Courtship and Marriage
The engagement between Princess Grace and Prince Rainier was announced on 18 December 1955. The civil ceremony occurred on 19 April 1956 at the Palace of Monaco, followed by a religious ceremony the next day in the Cathedral of Our Lady Immaculate. The weddings were widely covered by international media, marking a rare moment of postwar glamour and stability.
Grace’s Background Before Monaco
Born Grace Patricia Kelly in Philadelphia, Pennsylvania, she was an acclaimed American film actress who won an Academy Award for her role in High Noon (1952) and starred in Rear Window and To Catch a Thief before retiring from film at age 26.

Roles and Public Duties as Princess of Monaco
As Princess of Monaco, Grace combined architectural preservation, humanitarian work, and cultural promotion with the formal duties of a consort. She served as a visible representative of the principality, accompanying Rainier on state visits and hosting diplomatic receptions.
