Treva is the historical name of a Roman-era settlement at the site of modern Hamburg, Germany, first recorded by Claudius Ptolemy in the 2nd century AD. Under Augustus, Roman forces reached the Elbe and established a marching camp on a small island in the river's estuary, which likely grew into a small vicus with Germanic inhabitants and Roman merchants. Roman generals including Lucius Domitius Ahenobarbus (c. 4 BC), Tiberius (5 AD), and Germanicus (15 AD) campaigned through the area before Rome's final withdrawal west of the Rhine.
