"Though theoretically the position of the Shudras was very low, there is evidence to show that many of them were well-to-do. Some of them succeeded in marrying their daughters in royal families. Sumitra, one of the 3 wives of king Dasharatha, was a Shudra. Some of them even worked their way up to throne. The famous Chandragupta is traditionally known to be a Shudra."
