Draco enlisted in Hogwarts in September 1, 1991 and soon became the nemesis of fellow student Harry Potter. He had originally offered his friendship to Harry but was enraged when he was turned down in favor of Ron Weasley, who he apparently views as inferior to him. Conditioned by his father, Draco is obsessed with the "right sort of people" (meaning pure-blooded wizards and witches of the wealthier classes) and hates Muggles. Draco is constantly accompanied by two fellow Slytherins who seem to view him as their leader: Vincent Crabbe and Gregory Goyle.
Malfoy and Harry tangle repeatedly throughout the series, with an annual confrontation in the Hogwarts Express where Harry always gets the best of him.
The Harry Potter movies have Tom Felton as Draco.
Later in the series, readers learn that Draco's father Lucius Malfoy was a Death Eater and supporter of Lord Voldemort during Voldemort's earlier reign of terror that ended with the death of Harry's parents. When Voldemort returns and summons his Death Eaters, Lucius is among those that respond to join him again.
However, near the end of Book Five, Harry Potter and the Order of the Phoenix, Lucius Malfoy is caught and sent to Azkaban for the use of Unforgivable Curses, an event for which Draco blames Harry Potter completely.
Draco's graduation can be estimated to have happened in 1998 at the age of eighteen-years old but has not yet been depicted in the series.
The name Malfoy is derived from the French mal foie or mal foy, meaning bad faith or unfaithful. Which is fitting for the son of a Death Eater. Draco Malfoy's first name may be a reference to Draco, the first lawgiver of Athens who created a harsh law code.
