Pierre Rainier Stefano Casiraghi (born 5 September 1987) is the younger son of Caroline, Princess of Hanover, and her second husband, Stefano Casiraghi. Casiraghi is third in line to the throne of Monaco, following his mother and brother.
Early life and education 
Casiraghi was born at The Princess Grace Hospital Centre in Monte Carlo. He is named after his maternal great-grandfather, Prince Pierre, Duke of Valentinois, his maternal grandfather, Prince Rainier III, and his father. His godparents are his uncle, Prince Albert II, and his aunt by marriage Laura Sabatini Casiraghi, the wife of his uncle Daniele. Casiraghi was three years old at the time of his father's death in a boating accident. He spent his earliest years, after his father's death, living at his mother's farmhouse in the quaint town of Saint-Rémy-de-Provence.
He attended a state school in Saint-Rémy-de-Provence. However, after his mother's remarriage to Ernst August V, Prince of Hanover, the family moved to Fontainebleau, to be nearer to Paris and London, the latter being where his new stepbrothers lived with their mother. It is assumed that Casiraghi passed the French Baccalaureate exam in the summer of 2005 since he shortly afterwards began university. One year later, in fact, he moved to Milan to begin a three-year undergraduate course in International Economics and Management at Bocconi University. Besides French, he is fluent in Italian, English, and knows some German. He also plays the saxophone.
Personal life 
It is believed that he uses his economics degree towards learning the business of his father's companies, which are also managed by his uncle Marco.
Casiraghi was linked to a number of young women during his university years in Milan. He was photographed out and about with fashion models. But Casiraghi's longest and most serious romantic attachment to date has been since May 2008 the aristocratic and outgoing Columbia University Politics student Beatrice Borromeo.
In February 2012, Casiraghi was briefly hospitalized following a physical altercation at a Manhattan nightclub. According to media reports, Casiraghi approached the table of businessman Adam Hock, models Natasha Poly, Anja Rubik and Valentina Zalayeva. Words were exchanged and an altercation ensued. Hock was arrested on four counts of assault, and he is alleged to have struck Casiraghi as well as three male friends. Hock contends Casiraghi was the aggressor. 
Humanitarian and business activities 
From 30 January to 13 February 2007, Casiraghi accompanied his mother on a humanitarian tour of Africa. They visited Niger, Burundi, the Democratic Republic of Congo, and South Africa on behalf of Princess Caroline's role as President of AMADE Mondiale.
In June 2009, Casiraghi became the majority shareholder of the Monaco-based construction company his father founded in 1984. His uncle Marco remains in the position of President over this company, which is Engeco S.A. The acquisition of the majority shares to Casiraghi's name was handled by the Milan-based legal firm Bird & Bird.
