My dear devotees,
the name of old mathura was madhupuri.madhu and ketav ,two brother established it.madhu and ketavs were more powerful devils.when they won all the gods then lord vishnu killed them between his legs.then lord vishnu landed on mathura.

mathurāḿ nāma vai purīm
Śatrughna had two sons, named Subāhu and Śrutasena. When Lord Bharata went to conquer all directions, He had to kill many millions of Gandharvas, who are generally pretenders. Taking all their wealth, He offered it to Lord Rāmacandra. Śatrughna also killed a Rākṣasa named Lavaṇa, who was the son of Madhu Rākṣasa. Thus He established in the great forest known as Madhuvana the town known as Mathurā.
