Who was the founder of punjab?

The region of Punjab, which means "Land of Five Rivers," does not have a single founder but has a rich history influenced by various cultures and rulers. It was historically significant for the Indus Valley Civilization and later became a prominent area under the rule of the Maurya and Gupta empires. In the context of Sikhism, Guru Nanak, the founder of the faith in the 15th century, is often associated with the spiritual and cultural identity of Punjab. The modern political landscape of Punjab has evolved through various historical events and leaders, including the establishment of the Sikh Empire by Maharaja Ranjit Singh in the early 19th century.
