Punjabi culture
The culture of the Punjab encompasses the spoken language, written literature, cuisine, science, technology, military warfare, architecture, traditions, values and history of the Punjabi people native to the northern part of the Indian subcontinent. The term 'Punjabi' can mean both a person who lives in Punjab and also a speaker of the Punjabi language. This name originates from the Persian language 'panj', (five), and 'ab', (water). Combined together the word becomes Panjab or Punjab: land of the five rivers. Indus River (the largest river in this five river system), and the five other rivers to the south eventually join Indus or merge into it later in the downstream of the Punjab valley. All the rivers start and flow out of the Himalayas. These other five rivers are Jhelum River, Chenab River, Ravi River, Beas River and Sutlej River.
Punjabi Language Movement
The Punjabi Language Movement (PLM) is a linguistic movement in Punjab, Pakistan aimed at reviving the Punjabi language, art, culture and literature in Pakistan. The Punjabi people constitute the largest ethnic group in Pakistan though Urdu is the national language and unlike Indian Punjab (where reading/writing Punjabi language is compulsory at every level from 2008 alongside a special Punjabi University at Patiala), Punjabi itself does not have an official status. 
The PLM's ideologies are based on Punjabi nationalism.
