Oa is a community and a tribe with origins in upper (Southern) Sindh, Pakistan and Rajasthan. This tribe has a distinct and unique history dating back thousands of years. They are sometimes considered to be of Rajput origin. However, not much is documented about this tribe. The latest reference to Oads is found in the poetry of the great poet of subcontinent Shah Abdul Latif Bhitai, who has praised Oads for their hard work and simplicity.
