**Patiala** was a Sikh princely state that lasted from 1714 to 1948. Its rulers were descended from Chaudhary Phul (1627-1689), a Sidhu Jat from Mehraj village in the Bathinda District of Punjab. The other Sikh states, such as Jind and Nabha, were also the descendants of Phul. Its capital was in the Malva region of Punjab, but its territory expanded from Bathinda to present-day Mohali. They were known as the Phulkian (Patiala) Dynasty.

The House of Phul, was a Jatt of Sidhu Clan, belonging to the Malva Region of Punjab. Their ancestors had converted to Sikhism in the early 1600s. They claim to be the descendants from the sidhu jats, who ruled in the 11th century. The migrated to the Malva region of Punjab, establishing themselves at present day Bathinda District of Punjab. 

The Sidhu Jatts and the Bhullar Jatts of the Bathinda district, never got along with each other, They were at war. But later Nanu Bhullar, got his daughter married in the house of these Sidhu Jatts, the ancestors of the Patiala State.

And it will not be part of the 12 Sikh Confederacies, it was also the year when Ala Singh died and his son Amar Singh had become the next ruler. Ahmed Shah Abdali, bestowed upon Maharajah Amar Singh, the title of Raja-i-Rajgan, and he also was allowed to strike his own coins. But the Sikh Nation was not to happy about this, and in years to come they the Phulkians would be traitors to the Khalsa Panth, and helping the British to attack the Sikh interior of Punjab. 

Even when Sardar Hari Singh Dhillon (r.1746-1764), the Sikh Bhangi Misl Maharaja of Amritsar, Tarn Taran Sahib and Lahore, found out about Ahmed Shah Abdali being in the Patiala Kingdom, he marched with a big army of dashing looking Sikh soldiers from the Majha, where the holy city of Amritsar is located, on Patiala Kingdom to chase the Ahmed Shah away, but on the way he was killed, by someone.
