PUNJAB

Punjab is a region straddling the border between India and Pakistan. The "Five Rivers" are Beas, Ravi, Sutlej, Chenab and Jhelum; all these are tributaries of the Indus river, Jhelum being the biggest one. Punjab has a long history and rich cultural heritage. The people of the Punjab are called Punjabis and their language is also called Punjabi. The main religions of the Punjab region are, in order of population, Islam, Sikhism and Hinduism.
Punjab (British India), 1903 The part of Punjab region where Punjabi is the majority language; divided between India and PakistanThe area now known as the Greater Punjab comprises what were once vast territories of eastern Pakistan and northern western India. The bigger section of the Punjab is owned by Pakistan (55% to India's 45%). It comprised, in its original sense, regions extending from Swat/Kabul in the west to Delhi in the east i.e. the area including parts of Afghanistan and the plains up to the Ganges.
The region, populated by Indo-Aryan speaking peoples, has been ruled by many different empires and ethnic groups, including Hindus, Jains, Buddhists, ancient Macedonians, Persians, Arabs, Turks, Mughals, Afghans, Balochis, Sikhs and British. In 1947, it was partitioned between British India's successor states with 4 out of the 5 rivers going to Pakistan and the remaining river was alloted to India.
The Pakistani Punjab now comprises the majority of the region together with the Hazara region of the North-West Frontier Province and Azad Kashmir. The Indian Government further sub-divided Punjab into the modern Indian states of Punjab, Haryana, Himachal Pradesh and Delhi. Many critics originally saw this as an attempt to fragment and weaken any attempt by Punjab to later claim a sovereign identity based on ethnicity, language or culture. The Pakistani part of the region West Punjab covers an area of 205,344 square kilometers (79,284 square miles), whereas the Indian State of Punjab is 50,362 square kilometers (19,445 square miles). Besides the Indian Punjab, the region also includes the areas of Jammu region and Himachal and Haryana states of India that were created out of East Punjab in 1966. The populations of the region are similarly divided as 86,084,000 (2005) in West Punjab (Pakistan) and 24,289,296 (2000) in the present-day State of (East) Punjab (India) and a further 30 million in the rest of the region. Punjabi is spoken by (approximately) 65% of population in Pakistani Punjab (another 25% speak Punjabi variants) and 92.2% in Indian Punjab.[1] The capital city of undivided Punjab was Lahore, which now sits close to the partition line as the capital of West Punjab. Indian Punjab has as its capital the city of Chandigarh. Previously, the capital of Undivided Indian Punjab was Shimla. Indian Punjab uses the Gurmukhi script, while Pakistani Punjab uses the Shahmukhi script

At the end I want to say that "India is existing on the world map just due to punjab"

"Punjabi, language of lions"

Punjabi ( in Shahmukhi script), ( in Gurmukhi script), (Pañjābī in transliteration) is an Indo-Aryan language spoken by inhabitants of the historical Punjab region (now split between Pakistan and India) and their diasporas. Speakers include adherents of the religions of Islam, Sikhism and Hinduism.
According to various sources, Punjabi has approximately 90-100 million native speakers, which makes it approximately the 11th most widely spoken language in the world. According to the Ethnologue 2005 estimate[4], there are 88 million native speakers of the Punjabi language. According to the 2002 census of Pakistan[5], there are approximately 63 million native speakers of Punjabi in Pakistan, and according to the Census of India, there are over 29 million Punjabi speakers in India.
Along with Lahanda and Western Pahari languages, Punjabi is unusual among modern Indo-European languages in being a tonal language.
In his Linguistic Survey of India, the linguist George Abraham Grierson used the word "Punjabi" to refer to several languages spoken in the Punjab region: the term "Western Punjabi" (ISO 639-3 pnb) covered Saraiki, while the term "Eastern Punjabi" referred to the language based on Majhi dialect (ISO 639-3 pan). The term "Punjabi language" today generally refers to "Eastern Punjabi" i.e. the language based on the Majhi dialect of the historical region of Majha, which spans the Lahore, Sheikhupura, Kasur, Gujranwala, Sialkot, Narowal, Gujrat and Jehlum Districts of the Pakistani Province of Punjab and Amritsar District and Gurdaspur District of the Indian State of Punjab.

HISTORY
Punjabi is an Indo-Aryan language like many other modern languages of South Asia. The Punjabi language is a descendant of Sauraseni Prakrit, which was the chief language of medieval northern India.
Punjabi emerged as an independent language in the 11th century from the Sauraseni Apabhramsa.[15] Punjabi has been related to Sanskrit in the Vedic period (1700 B.C.), Pali, Prakrit and Apabhramsha in the Ashoka period (273 B.C. - 232 B.C.) and Hindvi, Lahori and Multani in the Muslim period (711 A.D. - 1857 A.D.). The literary tradition in Punjabi started with Fariduddin Ganjshakar (Baba Farid)(1173-1266), many ancient Sufi mystics and later Guru Nanak Dev ji, the first Guru of the Sikhism. The early Punjabi literature was principally spiritual in nature and has had a very rich oral tradition. The poetry written by Sufi saints has been the folklore of the Punjab and is still sung with great love in any part of Punjab.
Between 1600 and 1850, Muslim Sufi, Sikh and Hindu writers composed many works in Punjabi. The most famous Punjabi Sufi poet was Baba Bulleh Shah (1680 – 1757), who wrote in the Kafi style. Bulleh Shah practiced the Sufi tradition of Punjabi poetry established by poets like Shah Hussain (1538 – 1599), Sultan Bahu (1629 – 1691), and Shah Sharaf (1640 – 1724). His lifespan also overlapped with the legendary Punjabi poet Waris Shah (1722 – 1798), of Heer Ranjha fame. Waris Shah's rendition of the tragic love story of Heer Ranjha is among the most popular medieval Punjabi works. Other popular tragic love stories are Sohni Mahiwal, Mirza Sahiba and Sassi Punnun. Shah Mohammad's Jangnama is another fine piece of poetry that gives an eyewitness account of the First Anglo-Sikh War that took place after the death of Maharaja Ranjit Singh.
