Marriage was the formally recognized union of two beings as partners in a relationship. A marriage ceremony, which could be presided over by a clergy member, was referred to as a wedding. In the Jedi Order, attachment and possession were forbidden, because they could lead to jealousy and fear of loss, and ultimately the dark side of the Force. For that reason, Jedi were not allowed to marry. Despite that, the Jedi apprentice Anakin Skywalker still married Senator Padmé Amidala shortly after the First Battle of Geonosis, during a secret ceremony held on Naboo. In some cultures, males had more than one spouse at a time, such as the alpha-bulls of the Crolute species who had senior spouses, junior spouses, and concubines. Marriage between two beings of the same sex also occurred.

Marriages could be dissolved through divorce.
