French nobility and French title of "count" controversy
Although Danish law never required that royal spouses be of aristocratic origin, no heir's marriage to a person who lacked male-line descent from royalty or titled nobility had been accepted as dynastic by the sovereign in the course of Denmark's history as a hereditary monarchy, until the marriage of the heir presumptive, Princess Margrethe, in June 1967 to "Count" Henri de Laborde de Monpezat. Six months later Margrethe's first cousin, Prince Ingolf of Denmark, married an untitled commoner and was demoted to a count, and when another cousin, Prince Christian of Denmark, also wed a Dane, Anne Dorte Maltoft-Nielsen, in 1971, he forfeited his dynastic position.
