Xantoran

The Xantorans were a species native to the planet Xantoras.

They had a very unstable government that was known to change hands every few years. In 2153, when the visited the planet, the current government had been in power since the late 2140s, but was overthrown by a xenophobic militant group, leading to the visit of the Enterprise to rescue three Denobulan scientists.

When the Enterprise took longer to rescue the scientists than the new government had allotted, a Xantoran patrol ship fired upon them, leading Commander Tucker to suggest that it was just a "kick in the pants" to hurry up to the ship.
