The Phillaur post has an intriguing history behind it. Arranged on the Grand Trunk Road, it has an extraordinary verifiable foundation. The town of Phillaur in which the post is found owes its root to a Sanghera Jat, Phul, who named it after himself as "Phulnagar". The Naru Rajputs of Mau, an adjacent township, had taken a gander at Phillaur and inevitably under their Chief Rae Shahr they wrested it from the Jats. Rae Rattan Pal, the child of Rae Shahr, enjoyed it so much that he relinquished Mau and settled in Phillaur. The Jats at that point left the place.Later, in any case, at some period obscure, the Rajputs additionally abandoned it. Nothing is known from that point until the rule of the Mughal Emperor Shah Jahan (1627-1658) when a magnificent Sarai was worked at Phillaur. Afterward, the town was involved by Kakarah Sikhs and held until Maharaja Ranjit Singh (1780-1839) held onto all the Kakarah Estates. After the breakdown of the Mughal Empire, Maharaja Ranjit Singh sent Dewan Mohkam Chand,about the year 1809, to claim the Imperial Serai and changed over it into a considerable Fort with the assistance of his French and Italian officials, specifically Generals Ventura, Allard, and Avitabile. It was worked in answer to the British who had fabricated a little Fort at Ludhiana on the remainders said to be of an old Lodhi Fort, and to protect the ship of Phillaur. The British involved this Fort in 1846 after the Sikhs were vanquished in the clash of Aliwal. Phillaur, from that point, turned into a Cantonment and Fort stayed under the charge of Army experts till 1890 when it was given over to the Civil specialists and has been utilized from that point for police preparing purposes. The fortification was renamed as 'Maharaja Ranjit Singh Fort' by the Punjab Government by a warning dated sixth April, 1973.
