As early as Celtic and Roman times, Cochem was settled. In 886, it had its first documentary mention as Villa cuchema. Other names yielded by history are Cuhckeme and Chuckeme in 893, Cochemo in 1051, Chuchumo in 1056, Kuchema in 1130, Cuchemo in 1136, Cocheme in 1144, then Cuchme, and into the 18th century Cochheim or Cocheim. Cochem was an Imperial estate. It was pledged by King Adolf of Nassau in 1294 to the Archbishopric of Trier and remained Electoral-Trier territory until the French occupation began in 1794. In 1332, Cochem was granted town rights, and shortly thereafter, the town fortifications, which still stand today, were built. Between 1423 and 1425, the town was stricken with a Plague epidemic. In 1623, Elector Lothar von Metternich brought about the founding of a Capuchin monastery. In the Thirty Years' War, the town was besieged, but not conquered. In 1689, King Louis XIV's troops first burnt the Winneburg (castle) down and then conquered the town of Cochem with its castle. Reconstruction was long and drawn out. Beginning in 1794, Cochem lay under French rule. In 1815 it was assigned to the Kingdom of Prussia at the Congress of Vienna.
