On July 12th 1799 Ranjit Singh conquered Lahore and became Maharaja of the Sikh Empire. He then rapidly annexed the rest of the Punjab, the land of the five rivers. Having accomplished this, he extended his empire further north and west to include the Kashmir mountains and other Himalayan kingdoms, the Sind Sagar Doab, the Pothohar Plateau and trans-Indus regions right up to the foothills of the Sulaiman Mountains.
The Sikh Empire was a major power in the Indian subcontinent, that arose under the leadership of Maharaja Ranjit Singh who established a secular empirebasing it around the Punjab. The empire existed from 1799, when Ranjit Singh captured Lahore, to 1849 and was forged on the foundations of the Khalsa from a collection of autonomous Sikh misls. At its peak in the 19th century, the Empire extended from the Khyber Pass in the west to western Tibet in the east, and from Mithankot in the south to Kashmir in the north. It was the last major region of the subcontinent to be conquered by the British.
