Majha
The partition split the Punjab Province (British India) into the two states of West Punjab (Punjab, Pakistan) and East Punjab. However, the historic Majha region is arguably still the same as before since the partition does not change the previous history of Punjab, therefore does not change the geography of the Majha region of the historic Punjab region.
Punjab, India
The Sikh Empire was finally dissolved, after a series of wars with the British at the end of the Second Anglo-Sikh War in 1849, into separate princely states and the British province of Punjab, which were granted statehood. Eventually, a Lieutenant Governorship was formed in Lahore as a direct representative of the British Crown.
The Cis-Sutlej states, including Kaithal, Patiala, Jind, Thanesar, Maler Kotla, and Faridkot, were under the suzerainty of the Scindhia dynasty of the Maratha Empire, following the Second Anglo-Maratha War of 1803–1805, when Marathas lost this territory to the British. During the war, some of the states in the region gave their allegiance to British General Gerard Lake. At the conclusion of the Second Anglo-Maratha War, an 1809 agreement with Ranjit Singh, ruler of the Sikh Empire west of the Sutlej, brought these states under formal British protection.
