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
There are two main definitions of the Punjab region: the 1947 definition and the older 1846–1849 definition. A third definition incorporates both the 1947 and the older definitions but also includes northern Rajasthan on a linguistic basis and ancient river movements.
