Created by the Mr Star Trek himself Gene Roddenberry.
Earth: Final Conflict aired for 5 seasons between 6 October 1997 and 20 May 2002 was originally created by Gene Roddenberry. However, it was not put into production and televised until after his death.
The original title for the show was Battleground: Earth, but the producers changed it because it sounded too much like the founder of scientology, L. Ron Hubbard's novel, Battlefield Earth.
Majel Barrett, the wife of Gene Roddenberry, was the Executive Producer. She also appeared in some early episodes as the character Dr. Julianne Belman. Barrett is in possession of notes Roddenberry kept of story and series ideas; after his death, these notes provided the basis for this series.
Early in the 21st century, a race of aliens, the Taelons, arrive on Earth. In exchange for being allowed to take refuge on our planet, the Taelons offer the people of Earth access to their advanced technology. As a result, disease, war, and pollution are nearly eliminated. Despite all these advances, there are some people who think the Taelons are not as benevolent as they seem. A resistance movement is organized.
The show is unusual in that ultimately, the Taelon aliens are not purely evil (except for one character who eventually becomes the main villain in seasons 2-4), nor are they actually trying to "conquer" the world. However, they do have a hidden agenda, and have no problem violating basic individual civil liberties to reach their goals.
