Punjab

Punjab is of Persian origin, its two parts (پنج, panj, 'five' and آب, āb, 'water') are cognates of the Sanskrit words, पञ्‍च, pañca, 'five' and अप्, áp, 'water', of the same meaning. The word pañjāb thus means "The Land of Five Waters", referring to the rivers Jhelum, Chenab, Ravi, Sutlej, and Beas.[5] All are tributaries of the Indus River, the Sutlej being the largest. References to a land of five rivers may be found in the Mahabharata, which calls one of the regions in ancient Bharat Panchanada (Sanskrit: पञ्चनद, romanized: pañca-nada, lit. 'five rivers'). Persian place names are very common in Northwest India and Pakistan. The ancient Greeks referred to the region as Pentapotamía (Greek: Πενταποταμία),which has the same meaning as the Persian word.

The boundaries of the region are ill-defined and focus on historical accounts and thus the geographical definition of the term "Punjab" has changed over time. In the 16th century Mughal Empire the Punjab region was divided into three, with the Lahore Subah in the west, the Delhi Subah in the east and the Multan Subah in the south. In British India, until the Partition of India in 1947, the Punjab Province encompassed the present-day Indian states and union territories of Punjab, Haryana, Himachal Pradesh, Chandigarh, and Delhi, and the Pakistani regions of Punjab, and Islamabad Capital Territory. The predominant ethnolinguistic group of the Punjab region are the Punjabi people, who speak the Indo-Aryan Punjabi language. Punjabi Muslims are the majority in West Punjab (Pakistan), while Punjabi Sikhs are the majority in East Punjab (India). Other religious groups include Hinduism, Christianity, Jainism, Zoroastrianism, Buddhism, and Ravidassia.

The Punjab region is noted as the site of one of the earliest urban societies, the Indus Valley Civilization that flourished from about 3000 B.C. and declined rapidly 1,000 years later, following the Indo-Aryan migrations that overran the region in waves between 1500 and 500 B.C. Frequent intertribal wars stimulated the growth of larger groupings ruled by chieftains and kings, who ruled local kingdoms known as Mahajanapadas.The rise of kingdoms and dynasties in the Punjab is chronicled in the ancient Hindu epics, particularly the Mahabharata.The epic battles described in the Mahabharata are chronicled as being fought in what is now the state of Haryana and historic Punjab. The Gandharas, Kambojas, Trigartas, Andhra, Pauravas, Bahlikas (Bactrian settlers of the Punjab), Yaudheyas, and others sided with the Kauravas in the great battle fought at Kurukshetra.According to Dr Fauja Singh and Dr. L. M. Joshi: "There is no doubt that the Kambojas, Daradas, Kaikayas, Andhra, Pauravas, Yaudheyas, Malavas, Saindhavas, and Kurus had jointly contributed to the heroic tradition and composite culture of ancient Punjab."
