a Pure-blood wizard in the employment of the Ministry of Magic. He worked for the Ministry as an Auror, but joined the reconstituted Order of the Phoenix in 1995 after being convinced of the return of Lord Voldemort. Working undercover within the Ministry, he fed the Order with information, and misdirected the Ministry's efforts to locate Sirius Black. In 1996, he fought in the Battle of the Department of Mysteries, and was later assigned to guard the Muggle Prime Minister, posing as his secretary. Forced into hiding following the fall of the Ministry to Lord Voldemort in 1997, Kingsley continued to oppose the new regime. In 1998, he fought in the Battle of Hogwarts, and was named Acting Minister for Magic in the aftermath. He was eventually named Minister for Magic officially, and worked hard to revolutionise the Ministry.
