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
Using the 1947 definition, the Punjab borders the Balochistan and Pashtunistan regions to the west, Kashmir to the north, the Hindi Belt to the east, and Rajasthan and Sindh to the south. Accordingly, the Punjab region is very diverse and stretches from the hills of the Kangra Valley to the plains and to the Cholistan Desert.
