Explanation:

The Malerkoltla is former princley state and only Muslim-dominated town of Punjab.

• Historically, Malerkotla owes its foundations in the 15th century to Sufi saint Sheikh Sadrauddin Sadar-i-Jahan, also known as Haider Sheikh.
• After the decline of the Mughal empire, Malerkotla’s rulers exercised greater independence and at the time of the invasion of India by Ahmad Shah Abdali from Afghanistan, they aligned with him.
• Ahmed Shah Abdali invaded India eight times from 1748 to 1767.
• In 19th century, Malerkotla became one among the cis-Sutlej states.
• Malerkotla continued under the British protection and the alliance with the neighbouring Sikh states till 1947 when it became the only Muslim majority Sikh state in East Punjab.
• After the dissolution of the princely states in 1948, Malerkotla joined the new state of PEPSU or Patiala and East Punjab States Union (PEPSU). PEPSU itself was dissolved in 1954 and Malerkotla became a part of Punjab.
