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
The Punjab (, {IPAc-en|-|ˈ|dʒ|æ|b}}, , ), also spelled Panjab (from Persian "panj", "five" + "āb", "water" or "river", thus "land of "five rivers""; Punjabi: ), is a geopolitical, cultural and historical region in South Asia, specifically in the northern part of the Indian subcontinent, comprising areas of eastern Pakistan and northern India. The boundaries of the region are ill-defined and focus on historical accounts.
