Justice League Task Force was an American monthly comic book series published by DC Comics from June 1993 to August 1996; it lasted 37 issues. At the time the Justice League was featured in three separate series: Justice League America, Justice League Europe (JLE) and Justice League Quarterly (JLQ). Justice League Task Force was a spinoff of Justice League Europe, a series which ran from April 1989 to May 1993. Like JLE, this team carried a United Nations charter which sanctioned their activities. In fact, JLTF was composed of several former JLE members. The team was called to action by Hannibal Martin, a representative of the U.N.. He asked that Martian Manhunter select a "strike team" of fellow Justice League members and to "lead them on a very special mission".
