Princess Christina of the Netherlands, who married the Cuban-born administrator of a day care center in New York City and renounced her royal right of succession, died on Friday in Noordeinde Palace in The Hague. She was 72.

A government statement said she had bone cancer.

Christina was the youngest of four daughters of Queen Juliana, who died in 2004, and her German-born husband, Prince Bernhard.

As a royal, she shunned the spotlight, focusing on singing and collecting art with her husband, Jorge Guillermo, whom she married in 1975, raising a spate of publicity.

Around the time they met, Christina had been living in New York and teaching music and French at a private school under the name Christina Van Oranje. Mr. Guillermo was described as an assistant director of a day care center in Harlem who had worked at Chase Manhattan Bank and was writing a book on opera. He had come to the United States in 1960 from Cuba with his father, a doctor, and his mother, a minister of higher education in the years before Fidel Castro took power.
