The Germani cisrhenani (Latin cis-rhenanus "on this side of the Rhine", referring to the Roman or western side), or "Left bank Germani",[1] were a group of Germanic peoples who lived west of the Lower Rhine at the time of the Gallic Wars in the mid-1st century BC.
These Germani were first described by Julius Caesar, who was writing specifically about tribes near the Meuse river, who had settled among the Belgae before Roman intrusion into the area. Tribes who Caesar named as being among the Germani cisrhenani included the Eburones, the Condrusi, the Caeraesi, the Segni and the Paemani.
Tacitus, writing around 100 AD when the region had been part of the Roman Empire, referred to these Germani next, saying that they were by his time called the Tungri. The "Germani" name had by this time become a term used more commonly to refer to many other peoples.
