bloodballs: The Unforgivable Curses are three of the most powerful and sinister spells known to the wizarding world. They are tools of the Dark Arts and were first classified as “Unforgivable” in 1717, with the strictest penalties attached to their use. The three curses consist of the Killing Curse (Avada Kedavra), Cruciatus Curse (Crucio), and Imperius Curse (Imperio). -- source link
