The Vedic Punjab.

The original Punjab region is now divided into several units: West Punjab (now in Pakistan), portions of eastern Afghanistan such as the Gandhara/Kandahar region, the Indian states of Punjab, Haryana and Himachal Pradesh and the Indian Union territory of Chandigarh. The regions of Azad Kashmir and Jammu have also been historically associated with the Punjab.

The Punjab is the 'Sapta Sindhu' region mentioned in the Rig Veda, the seven rivers are:

Saraswati (thought to be the present day Ghaggar)
Satadru/Shutadri (Sutlej)
Vipasa (Beas)
Asikani, Chandrabhaga (Chenab)
Iravati (Ravi)
Vitasta/Vet (Jhelum)
Sindhu (Indus)

The modern name of the Vipasa,'Beas' is thought to be a corruption of Veda Vyasa, the author of the Mahabharata.

Among the classic books that were wholly or partly composed in this region are the following.

Rigveda
Grammar of Sakatayana
Ashtadhyayi of Pāṇini
Nirukta of Yaska
Charaka Samhita
Mahabharata along with the Bhagavad Gita
Brihatkatha of Gunadya
The Bakhshali Manuscript

The world's oldest university Takshashila flourished here, even before the Buddha's birth.

The Brahmins of this region are called 'Saraswata' after the legendary Saraswati river region, once known for the ashramas of the rishis.
