The Planetarist movement was a political movement that formed in response to the founding of the United Federation of Planets. Most Planetarists felt that the United Federation of Planets was formed too quickly after the Earth-Romulan War and had serious concerns about the preservation of their cultures and individual liberties in the new nation. Unfortunately the movement was soon co-opted by criminal elements opposed to the Federation as the spread of the new nation's laws would put a damper on their activities.
