The Phulkian (or Phoolkian) sardars (local leaders) were Sikh rulers and aristocrats in the Punjab region of India. They claimed descent from the founder of Jaisalmer, Rawal Jaisal. They governed the states of Jind, Nabha and Patiala, allying themselves with the British Raj.
In Phul, a Sikh leader of the 18th century, the rulers of the Phulkian states shared a common ancestor. Those of Jind and Nabha were descended from Phul's eldest son, and the origins of the ruler of Patiala lay with another of his sons. All three also claimed descent from Rawal Jaisal, a Jadon Bhatti Rajput who founded Jaisalmer.
The Rajas of all three Phulkian states had supported the pre-Raj East India Company during the Indian Rebellion of 1857, both with military forces and supplies, as well as by offering protection for European people in affected areas. Despite this, in 1858 the British Raj authorities rejected a petition to allow them to adopt heirs to ensure lines of succession. They believed that such processes could be dealt with on an ad hoc basis if and when the situation arose, and that to accept the petition would be contrary to the Doctrine of Lapse. The matter was eventually taken up by the government in Britain, who demanded that the Raj authorities should grant the petition in recognition of the considerable loyalty that had been demonstrated during the rebellion. Thus, on 19 January 1860 at a durbar in Ambala, Charles Canning, the Governor-General of India, acceded to the request.
A dispute in the early 1920s between Bhupinder Singh, who had become Maharaja of Patiala in 1909, and his fellow Maharaja in Nabha, Ripudaman Singh, who became ruler in 1911, had significant ramifications both for relationships within the Sikh community and for British policy in the Punjab. According to historian Barbara Ramusack, the pair were "ambitious, arrogant, energetic, and jealous" and "shared the hypersensitivity on matters of izzat or honor and status common to most Indian princes". What began mostly as a war of words from around 1912 had become physical by the 1920s, with Bhupinder Singh complaining that the law courts of Ripudaman Singh had been falsely convicting Patiala police officers, as well as kidnapping girls from Patiala for the royal harem. On top of this were frequent boundary disputes, which had been a feature of strife between the states for many years because of the way in which the territories intertwined.
