Type of marriage in ancient Indian Society

According to Hinduism there are eight different types of Hindu marriages. Among the eight types not all had religious sanction. The first four were considered proper. Rakshasa and Gandharva marriage was regarded acceptable to Kshatriyas as was Asura marriage for Vaishyas and Shudras. The eight types are:

1. Brahma marriage: The Brahma marriage is the marriage of one's daughter, after decking her with costly garments and with presents of jewels, to a man of good conduct learned in the Vedas, and invited by oneself.
2. Daiva marriage: The Daiva rite is the marriage of one's daughter, decked with ornaments to a priest who duly officiates at a religious ceremony, during the course of its performance.
3. Arsha marriage: Arsha marriage is when the father gives away his daughter, after receiving from the bridegroom a cow and a bull or two pairs of either as bride price.
4. Prajapatya marriage: Prajapatya is when a girl's father gives her in marriage to the bridegroom, treating him with respect, and addresses them: 'May both of you perform together your duties'
5. Gandharva marriage: The voluntary union of a maiden and her lover which springs from sexual desire is called Gandharva marriage.
6. Asura marriage: Asura marriage is when the bridegroom receives a maiden, after having given of his own free will as much wealth as he can afford, to the bride and her kinsmen.
7. Rakshasa marriage: Rakshasa marriage is the marriage of a maiden involving her forcible abduction from her home after her kinsmen have been slain or wounded.
8. Paishacha marriage: When a man by stealth seduces a girl who is sleeping, intoxicated, or mentally challenged, it is called Paishacha marriage. This is condemned in the Manusmriti as a base and sinful act.

What is anuloma and pratiloma marriage?

Anuloma marriage: It is a marriage under which a man can marry from his own caste or from those below, but a woman can marry only in her caste or above. Pratiloma marriage: It is a marriage of a woman to a man from a lower caste which is not permitted. The Purana mentions that only under certain conditions can a woman marry for a second time. The conditions are namely moral degradation of her husband, his death, renunciation by him of all worldly pursuits, his resorting to a monastery. It has also been said that a widowed woman may marry the brother of his husband or as an alternative she may marry anyone of her choice.
