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
In 1758, Punjab came under the rule of Marathas, who captured the region by defeating the Afghan forces of Ahmad Shah Abdali. Abdali's Indian invasion weakened the Maratha influence, but he could not defeat the Sikhs. After the death of Ahmad Shah, the Punjab was freed from the Afghan yoke by Sikhs between 1773 and 1818. At the time of the formation of the Dal Khalsa in 1748 at Amritsar, the Punjab had been divided into 36 areas and 12 separate Sikh principalities, called misl. From this point onward, the beginnings of a Punjabi Sikh Empire emerged. Out of the 36 areas, 22 were united by Maharaja Ranjit Singh. The other 14 accepted British sovereignty. After Ranjit Singh's death, assassinations and internal divisions severely weakened the empire. Six years later the British East India Company was given an excuse to declare war, and in 1849, after two Anglo-Sikh wars, the Punjab was annexed by the British.
