Explanation:

• Allahabad is located at the confluence of the Ganga, Yamuna and the mythical, unseen Saraswati.
• Mughal emperor Akbar is credited with the building of the modern Allahabad city in the 16th century, when he constructed a fort that overlooked the sangam, which then had immense strategic value.
• It is this Mughal connection that seems to be driving the revanchists who wants to wipe out all references to Mughal history.
• Akbar is said to have chosen the name Ilahabad for the city to press his syncretic religious idea espoused in the Din-i Ilahi; Ilahabad is the city of gods, its pluralistic heritage includes not just Hindu and Islamic traditions but also a Christian lineage derived from its colonial inheritance.
• According to state government, Prayag is where Lord Brahma performed the first yagna. The confluence of two rivers is a 'prayag', and in Allahabad three rivers Ganga, Yamuna and Saraswati meet. Hence, it is the king of 'prayags'.
