According to the search results, Lucius Malfoy was a Death Eater who actively participated in the first wizarding war as Voldemorts second-in-command. After Voldemorts downfall on the fateful night of Halloween in 1981, many Death Eaters were captured, but Lucius avoided being imprisoned by claiming that he was under the Imperius Curse throughout the war. He managed to retain his position among the social elite but still remained a power-hungry bigot. During the Second Wizarding War, Lucius initially renewed his loyalty with Voldemort, but his station with Voldemort waned over the series, and the family became increasingly disenfranchised with their master. By the Battle of Hogwarts, Lucius abandoned his loyalty to Voldemort to protect his family, and was pardoned for his crimes due to his last-minute defection. After the war, the Malfoys returned to their average daily lives of affluence, and Lucius seemed to show no regret for betraying Voldemort. It is also mentioned that Lucius is now on distant terms with his son, Draco, who has renounced his familys dark past.
