Mir Mannu becomes the new Subedar of the Punjab
Mir Mannu became the new governor of the Punjab on April 9, 1748. He appointed Kaura Mal as his new Diwan (minister). After taking control of the administration of the provinces, he employed his army to fight the Sikh misls or fighting orders. The Sikhs left the territory and moved to other states. The Sikh Chiefs asked Jassa Singh Ramgarhia to liaise with the subedar (governor) of the Jullundur Doab, Adina Beg Khan. While drawing his salary from the Mughals, Adina Beg Khan joined forces with the Jassa Singh Ramgarhia against the Mughals.
The siege of Ram Rauni
The Sikhs gathered in Amritsar on Diwali,1748. Adina Beg proceeded towards Amritsar and besieged Ram Rauni. Mir Mannu came down from Lahore with an army to assist Beg in the siege.
Jassa Singh used the good offices of Diwan Kaura Mal and had the siege lifted. The fort was strengthened and re-named Ramgarh. Jassa Singh, having been designated the Jathedar of the fort, became popular as Ramgarhia.
Fighting tyranny
Mannu intensified his violence and oppression against the Sikhs. There were only 900 Sikhs when he surrounded the Ramgarh fort again. The Sikhs fought their way out bravely. The army demolished the fort. The hunt for and torture of the Sikhs continued until Mannu died in 1753.
Manu’s death left Punjab without any effective Governor. It was again an opportune period for the Sikhs to organize themselves and gain strength. Jassa Singh rebuilt the fort and took possession of some areas around Amritsar. The Sikhs took upon themselves the task of protecting the people in the villages from the invaders. The money they obtained from the people was called Rakhi (protection charges).
The new Governor, Prince Timur, the son of Ahmed Shah Abdali, despised the Sikhs. In 1757, he again forced the Sikhs to vacate the fort and move to their hiding places. The fort was demolished, the Harimandir was blown up, and the sacred pool was filled with debris. The Governor decided to replace Adina Beg. Beg asked the Sikhs for help and they both got a chance to weaken their common enemy. Adina Beg won the battle. The Sikhs rebuilt Ramgarh and repaired the Harimandir. Beg was well acquainted with the strength of the Sikhs and he feared they would oust him if he allowed them to grow stronger, so he lead a strong army to demolish the fort. After fighting valiantly, the Sikhs decided to leave the fort. Beg died in 1758.
The Ramgarhia Misl Estate
Jassa Singh Ramgarhia occupied the area to the north of Amritsar between the Ravi and the Beas rivers. He also added the Jalandhar region and Kangra hill areas to his estate. He had his capital in Sri Hargobindpur. The large size of Jassa Singh’s territory aroused the jealousy of the other Sikh Misls.
Intra Misl wars
Although Jai Singh Kanhaiya and Jassa Singh Ramgarhia were once close friends, their rivalries led to a pitched battle between them and their allies. The chiefs of the Bhangi Misls joined the Ramgarhias and their associates. Jai Singh Kanhaiya was joined by Charhat Singh Sukerchakia and Jassa Singh Ahluwalia. The Ramgarhia side lost the battle.
Later, Ahluwalia while hunting one day, happened to enter Ramgarhia territory where Jassa Singh’s brother arrested him. Jassa Singh apologized for the misbehavior of his brother, and honorably returned Ahluwalia with gifts. However, their old differences increased further. The other chiefs also took a grim view of this act.
Due to mutual jealousies, fights continued among the Sikh Sardars. In 1776, the Bhangis changed sides and joined Jai Singh to defeat Jassa Singh. His capital at Sri Hargobindpur was taken over and he and his forces were pursued from village to village. Finally he lost all his territory. He choose to cross the river Satluj, going over to Amar Singh, the ruler of Patiala.
Amar Singh welcomed the Ramgarhia sardar in order to make use of his bravery, fighting skill, and ruling experience. He gave him the areas of Hansi and Hissar which Jassa Singh handed over to his son. He himself joined Amar Singh to take control of the villages on the west and north of Delhi, now forming parts of Haryana and western Uttar Pradesh. Jassa Singh Ramgarhia entered Delhi in 1783. Shah Alam II, the Mughal emperor, extended him a warm welcome. Ramgarhia left Delhi after receiving gifts from him.
Meanwhile to the north, differences over how to divide the Jammu state revenues, resulted in long time friends and neighbours Maha Singh, Jathedar of the Sukerchakia Misl and Jai Singh, Jathedar of the Kanahya Misl, becoming enemies. This rancor resulted in a war which would change the course of Sikh history.
Maha Singh requested Jassa Singh Ramgarhia’s aid. In the ensuing battle, Jai Singh Kanahya lost his son, Gurbaksh Singh in the fighting with the Sukerchakias and the Ramgarhias.
The unification of the Misls
Sada Kaur, the newly widowed daughter-in-law of Jai Singh, proved to be a great statesperson. Though very young she could see the end of Khalsa power if such internescine battles continued, she now worked to unite the waring misls in order to form a united, formidable force. She was able to convince Maha Singh to adopt the path of friendship by offering the hand of her daughter, then only a child, to his son, himself just a young boy, Ranjit Singh the future Maharaja of the Punjab. The balance of power now shifted in favor of this united Misls as other sardars also joined the union. Ranjit Singh was now the leader of the most powerful Sikh Misl ever.
Establishment of the Sikh Kingdom of the Punjab
When the Afghan invader, Shah Zaman, came in 1788, the Sikhs, however, were still divided. The Ramgarhia and Bhangi Misls were not willing to help Ranjit Singh to fight the invader, so the Afghans took over Lahore and looted it. As soon as the Afghans went back, Ranjit Singh occupied Lahore in 1799 but the Ramgarhias and Bhangis did not accept him as the leader of all the Sikhs. They got the support of their friends and marched to Lahore to challenge Ranjit Singh. The forces, who were 12 miles outside the city, were finalizing their plans to attack, when the Bhangi leader died. This discouraged Jassa Singh and he returned to his territory.
Demise
Jassa Singh was eighty years old when he died in 1803. His son, Jodh Singh, developed good relations with Ranjit Singh and they never fought again.
Because of Jassa Singh Ramgarhia’s Tarkhan roots, Tarkhans who became Sikhs, came to be known as Ramgarhias. Jassa Singh left behind two sons Jodh Ramgarhia and Bir Ramgarhia. His four brothers Mali Singh Sehmi, Jai Singh Sehmi, Khushal Singh Sehmi and Tara Singh Sehmi. His direct descendants include Baldip Singh Sehmi (Architect) Ajit Singh Sehmi ( Accountant) Heronimo Sehmi (Actor /Director) Pritpal Singh Sehmi ( Singer/Songwriter) Joshuah Dipp Kalsi ( Publisher/Singer/Songwriter) Darshan Singh Sehmi Gain Kaur Sehmi there are 215 direct descendants.
