In 1794, Nizamuddin and his younger brother Qutbuddin, established themselves as rulers of
Kasur. Following the death of his elder brother, Qutbuddin began to openly challenge the authority of
Maharajah Ranjit Singh and in February 1807, the Maharajah marched on Kasur and removed Qutbuddin from power. As a gesture of goodwill the Maharajh granted Qutbuddin the
jagir of Mamdot, territory which he had recently acquired from the
Rai of
Raikot. In 1831, Qutbuddin was ousted as jagir by his nephew Fatehuddin and soon after died in
Amritsar. The Maharajah in turn replaced Fatehuddin with Jamaluddin, the eldest son of Qutubudin. In 1845, the
East India Company offered to confirm Jamaluddin's status in return for support during the forthcoming
Sutlej Campaign. Jamaluddin opposed the British at the battles of
Mudki and
Ferozeshah and in the latter his brother Fatehuddin was killed. Towards the end of the campaign, sensing a British victory, he offered them support at
Ferozepur when under attack by the
Khalsa Army. For this assistance, in 1848 the British allowed him to retain his possessions and awarded him the title of Nawab. However, later accusations of abuse of power and oppression led to an investigation against him, and he was stripped of his powers in 1855. The state of Mamdot subsequently became part of
Firozpur district and the title went into abeyance. On the death of Jamaluddin in 1863, the succession of Mamdot was disputed among the sons of Jamaluddin and his younger brother Jalaluddin. On 5 October 1864, the
Governor-General of India under the authority of the British Crown conferred the hereditary title of Nawab of Mamdot on Jalaluddin. Although he had opposed the British during the Sutlej Campaign, he was deemed untainted by his brother's mis-governance, and rewarded for faithful service during the
Second Anglo-Sikh War and the
Indian Rebellion of 1857. In 1870, Jamaluddin was made an Honorary Magistrate, and he died in 1875. His titles and possessions passed to his eldest son Nizamuddin. ==Nawabs of Mamdot==
