Note: Emerita was founded in 25 B.C. with the name of Emerita Augusta (the name Mérida is an evolution of this) by order of Emperor Augustus, to protect a pass and a bridge over the Guadiana river. Two veteran legions were the former settlers: V Alaudae and X Gémina. The city became the capital of Lusitania province, and one of the most important cities in the Roman empire.
