The Federation Peace Medal was an award that was given to members of the United Federation of Planets.
It was created originally by the Tellarite Planetary Government but was later adopted by the Federation on Stardate 2/2001 and officially made on 2/1005. The Peace Medal was given to an individual to commend their actions for setting a personal example of foestering peace, mutual respect as well as cooperation amongst divergent races. The design was later modified on Stardate 2/8801 and appeared as an elongated star set against a gold "Enterprise" arrowhead which was held in upraised hands.
Ambassador Elias Rinn was a recipient of it by Stardate 2/9905.17 when he brought the planet Halka into the Federation despite several decades of refusals from the Halkan High Council. (FASA RPG module: Star Trek: The Next Generation Officer's Manual)
