Basil Flack

Minister Basil Flack was Minister for Magic in 1752. He may have been appointed a temporary acting Minister instead of being elected by the wizarding population due to the crisis of the goblin rebellions.

He was the Minister for Magic with the shortest term as of 2014, only holding the office for two months. He resigned from the post after the goblins joined forces with the werewolves, presumably as part of the same rebellion that sparked his predecessor's resignation.

Etymology
Basil is a given name derived from the Greek βασιλεύς, meaning "king". Flack is an alternate spelling of the word flak, which is English slang for "adverse criticism".
