The founder of the Kaithal clan was Gurbakhsh Singh, one of the chiefs of the Phulkian families. His son, Desu Singh, captured the town of Kaithal from its ruling Afghan chief in 1767 and gradually enlarged its borders. In May 1809, the State of Kaithal became a British protectorate.
The last ruler of Kaithal, Bhai Udai Singh, died in 1843 without leaving any heir. The State of Kaithal was annexed by the British Government of India.
Lal Singh ruled the Kaithal princely state from 1781 to 1819 AD. During the reign, he issued gold Mohur and silver Rupee. One of his gold Mohur which depicted above was issued in the name of Ahmad Shah Durrani.
