"Morganatic marriage, sometimes called a left-handed marriage, is a marriage between people of unequal social rank, which in the context of royalty or other inherited title prevents the principal´s position or privileges being passed to the spouse, or any children born of the marriage.
Generally, this is a marriage between a man of high birth (such as from a reigning, deposed or mediatised dynasty) and a woman of lesser status (such as a daughter of a low-ranked noble family or a commoner). Usually, neither the bride nor any children of the marriage have a claim on the bridegroom´s succession rights, titles, precedence, or entailed property. The children are considered legitimate for all other purposes and the prohibition against bigamy applies. In some countries, a woman could also marry a man of lower rank morganatically. As a result of the above, a king deciding to enter into a morganatic marriage who does not have children from a previous marriage thereby gives up the chance of being succeeded by his own children and accepts that succession would pass to his other relatives." - (en.wikipedia.org 13.07.2022)
