Rakshasa type of marriage is

In ancient Hindu legal texts like the Manusmriti, Rakshasa marriage is defined as the seventh of eight forms of marriage, characterized by the forcible abduction of a maiden from her home. This form involves seizing the bride by force, often after her kinsmen have been slain or wounded and their houses broken into. It is essentially a marriage by capture or physical force, historically associated with the Kshatriya or warrior class, where women were sometimes treated as prizes of war. While the Brahma and Daiva forms were considered approved (Prashasta), the Rakshasa form was classified as unapproved (Aprashasta) and condemned due to its violent nature. In contrast, marriage by purchase is known as Asura marriage, and marriage by seduction of an unconscious or sleeping woman is termed Paishacha marriage.
