Draupadi, of the epic Mahabharata was married to five brothers. Following her, the women of Osla, a small village in garwal himalaya of India, were given the freedom or may be forcefully married to all the brothers of the same family. The custom is no more in practice, but still you will meet the old women of the village who were married under such custom. The shortage of girls in the area or limitation of agricultural land might be considered as a reason for such customs during that time.
