James Potter was born on March 27, 1960 into a pure-blood wizarding family of considerable wealth. Both of his parents were elderly, even by wizarding standards, and they both died under normal circumstances between 1975 and 1981. Because he was their only child, arriving later in their lives, James's parents pampered him a great deal, so he grew to be arrogant, boastful, and proud, but deep down a good person.
James started his first year at Hogwarts School of Witchcraft and Wizardry in 1971 and was sorted into the Gryffindor house. While there, he befriended Sirius Black III, Remus Lupin, and Peter Pettigrew, and together they called themselves the Marauders.

However, it was later revealed that James and Sirius had insulted Snape from the moment they met him in their first year on the Hogwarts Express. Snape followed the Marauders around, looking for reasons to get them expelled. James, in turn, used the hexes Snape himself had made up against him.
James spent the majority of his academic career chasing after Lily Evans, an attractive fellow Gryffindor whom he called by her surname. Lily was perhaps the only student in the school, aside from Snape, who was completely unimpressed by James, considering him arrogant and obnoxious. She once ordered James to quit hexing Snape, and James said, "I will if you'll go out with me, Evans". When James took the curse off
