The Tencteri were a Germanic people during the first centuries BC and AD, who lived east of the Rhine delta. They were first reported by Roman sources during the Gallic Wars of Julius Caesar in 55 BC. He attacked a very large group of Tencteri and Usipetes near the Rhine delta, while they were on the move with women, children and the elderly, having left their homelands east of the delta under pressure from the Suebi. Caesar reported that large numbers were killed, but survivors managed to cross the Rhine and seek refuge with the Sugambri.
