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.
United District of Punjab
The United Districts of Punjab, or loosely labeled Punjab, is a proposed idea that allows the Indian state of Punjab to declare sovereignty as a territory of the United States of America, and a share-point between the governments of India and USA.
