The Majha ( Punjabi: ਮਾਝਾ ( Gurmukhi), ( Shahmukhi); Mājhā) is a region that is located at the center of the historical Punjab region, that is northward from the right banks[note 1] of river Beas, and extends up to river Jhelum at its northmost. It includes a considerable portion of the Bari Doab (the region between the rivers Beas and Ravi) and the Rechna Doab (the region between the rivers Ravi and Chenab), and a smaller portion of the Jech Doab region (the region between the rivers Jhelum and Chenab). People of the Majha region are given the demonym "Mājhi". The standard dialect of the Punjabi language known as the Majhi dialect is the main language of this region.
During the partition of India in 1947, the Majha region of Panjab got split into India and Pakistan when Panjab India and Punjab Pakistan were formed. The Majha region of Indian State of Panjab covers the area between Beas and Ravi rivers, including the area on the north of Sutlej, after the confluence of Beas and Sutlej at Harike in Tarn Taran district, extending up to the Ravi river, which is all part of the Majha region in India. This region contains four districts of Indian state of Panjab - Amritsar, Tarn Taran, Gurdaspur, and Pathankot.
The Majha region has always been the central point of Panjab. It was densely populated and the most productive region of Panjab in the past. Due to its location, its rich Punjabi culture, and being the focal point of Panjab, it has also been an appealing land for many foreign invasions for centuries. The Majha people have always retaliated to the invasions, which has made people of Majha valiant, fearless but also god-loving, giving birth to many renowned and ferocious warriors and martyrs. The Majha region is also the birthplace of Sikhism, where most Sikh Gurus were born. The Sikh Empire under the leadership of Maharaja Ranjit Singh had its capital in Lahore which is in Majha. Greek writers have referred to the people of Majha as the back-bone of the Sikh people, who have been recognized to have the highest reputation for courage and skill in the art of war. The Majhi (people of Majha) not only defeated the courageous Paurava but also fought Alexander the Great by the sakata-vyuka or 'waggon-formation' even though they were hopelessly outnumbered by the Greeks and defeated the Greek phalanx.
