What Happened To Lucius Malfoy After The War In Harry Potter?
The Malfoys are one of the most interesting factions in the world of J.K. Rowling's "Harry Potter" series. Uptight and aristocratic, the pure-bred Malfoys shun wizards who are related to or affiliate themselves with the muggle population. Their high level of wealth and affluence has granted them great influence within the magical community. When Voldemort returns in "Harry Potter and the Goblet of Fire," the Malfoys are some of the first ex-Death Eaters to renew their loyalty with the Dark Wizard. However, their station with Voldemort wanes over the series, and the family becomes increasingly disenfranchised with their master. By the end of Voldemort's life, the Malfoys had abandoned his cause.
Even Lucius Malfoy (played by Jason Isaacs in the films), the family's patriarch and one of Voldemort's most loyal followers, betrayed him in the final hour in order to protect his son, Draco. Because the Malfoys switched sides at the last second, they were granted amnesty for their crimes by the rest of the wizarding world. In the future, Lucius seemed to show no regret for betraying Voldemort, though other wizards still distrusted him and other Malfoys after the Second Wizarding War.
After the books, Lucius lives on
With their post-war amnesty, the Malfoys returned to their average daily lives of affluence. However, it seems as if they mostly stick to a low-profile existence even as Lucius continues to delve into dark magical artifacts. In the play "Harry Potter and the Cursed Child," which takes place after the "Deathly Hallows," it is revealed that Lucius worked with Theodore Nott to create a new time turner that lacked fewer restrictions than the one used in "Prisoner of Azkaban."
Though Lucius himself refrained from ever using the new time turner and its prototype, Voldemort's daughter Delphini would. This resulted in an altered timeline where Voldemort prevailed, and it took the combined efforts of Albus Severus Potter, Scorpius Malfoy, and alternate versions of the series' heroes to reverse the damage done to the timeline. Beyond this, however, Lucius had minimal involvement in any serious events following the Second Wizarding War.
