The Map was created during nights when the Marauders prowled the castle under James's Invisibility Cloak (Pm) The Map uses the Homonculus Charm to keep track of everyone at Hogwarts, and was embedded with a repelling spell directed at Snape.They put it to good use for years until they bequeathed it to Harry in December of 1993 ( PA10). The map was snatched from Filch's filing cabinet by Fred and George Weasley during their first year (1989-1990). The map was created by Remus Lupin, Peter Pettigrew, Sirius Black, and James Potter during their years at Hogwarts and at some point confiscated by Filch, who didn't know how to activate it but guessed that it was a magical item of some power.

The map looks like a large but empty piece of old parchment until it is activated with the words “I solemnly swear that I am up to no good.” To clear the map, the phrase “Mischief managed” must be spoken. A little miniscule figure of Harry only appeared once he gained possession of the map and needed to use it. It would seem that people only appear on the map if there is some reason for them to be there. The map also shows the location of people. However, it does not show the Room of Requirement or the Chamber of Secrets. This magical map of Hogwarts Castle shows the entire castle and grounds of Hogwarts, including seven secret passages out of Hogwarts and into Hogsmeade.
