The changes ended autocratic rule, placing power with the prince and a National Council of eighteen elected members. At the time of his death, he was the world's second longest-serving living head of state (independent), ranking just below the King of Thailand, Bhumibol Adulyadej. After a year-long courtship described as containing "a good deal of rational appraisal on both sides" ("The Times", 7 April 2005, page 59), Prince Rainier married Oscar-winning American actress Grace Kelly (1929–1982) in 1956.

Albert II, Prince of Monaco since Rainier was no longer able to exercise his royal functions. On 6 April 2005, Rainier III died and Albert succeeded him as Albert II. The first part of Prince Albert II's enthronement as ruler of the Principality was on 12 July 2005, after the end of the three-month mourning period for his father. A morning Mass at Saint Nicholas Cathedral presided over by the Archbishop of Monaco, the Most Reverend Bernard Barsi, formally marked the beginning of his reign. Afterward Albert II returned to the princely palace to host a garden party for 7,000 Monégasques born in the principality.
