United Nations of Earth

The myriad Human nations that constitute their interstellar government are disparate, yet united in purpose. These bipedal mammalians have developed a society that encourages and even thrives on individual freedoms and cultural differences - as a result, Humans tend to integrate well with alien populations.

Despite this, they have strong martial traditions (produced by millennia of intermittent warfare on their homeworld) and their sometimes aggressive and unpredictable nature should not be underestimated.
