Before it became a Princely State it was under the Nawab of Jhajjar. A war between the Army of Nawab and residents of Dujana & few other nearby villages took place. Locals confirm the war and reason was that the Nawab was willing to marry a Dujana girl but family and village denied for this. So, when the Nawab attacked the village an with army of 40,000 troops, all residents of Dujana and few nearby villages fought the war against the Nawab. Every male who was able to fight took part in the war and they defeated (literally by butchering) the Nawab's army and the Nawab was severely injured in this fight. However, their army saved him. In this war 60 to 70% of residents of Dujana & few nearby villages also lost their life, but they saved their honour, and after this a Princely State named with Dujana created.[citation needed] This was the smallest princely state.

Note: British Punjab province era district borders are not an exact match in the present-day due to various bifurcations to district borders — which since created new districts — throughout the historic Punjab Province region during the post-independence era that have taken into account population increases.
