Roman Empire Trajan 117AD

The Roman Empire at its greatest extent, during the reign of Trajan in 117 AD

The Roman Empire was a nation-state on Earth thousands of years prior to the creation of the Terran Federation, it was noted for its engineering feats, its strong governace, powerful military, and over-reliance on Slave Labour.  Unlike the Chinese Empire, it eventually succumbed to waves of barbarian hordes, leaving behind its massive aqueducts, and other engineering marelous as a statement of its former glory. 

The Roman legacy however, of its state religion, language, and concept of Pax Romana helped guide the world in future generations towards the peace and security of the Terran Federation. (MTAT)
