Prayag is the ancient Sanskrit name of Allahabad - a city in North India, situated on the confluence of three rivers: the Ganges, Yamuna and Saraswati - the Goddess of Learning. Sant Tulsidas describes this Prayag as Tirthraj ( King of all Tirthas ) in his classical epic Ram Charit Manas. When the sun crosses the line of Capricorn all the Tirthas, saints and other Rishis visit the Tirthraj Prayag.

The first three Universities (of Calcutta, Bombay and Madras) were established at the same time in 1857 by a decree of the British Government.
