Metz, the capital and the prefecture of the Moselle department in France, has a recorded history dating back over 2,000 years. During this time, it was successively a Celtic oppidum, an important Gallo-Roman city, the Merovingian capital of the Austrasia kingdom, the birthplace of the Carolingian dynasty, a cradle of Gregorian chant, and one of the oldest republics of the common era in Europe. As an important city in the heart of Europe and the crossroads of different cultures, Metz has variously experienced an integration into the Roman Empire, the period of christianization, the barbarian depredations, religious wars, the French Revolution, the Industrial Revolution, an annexation into the German Empire, and World War II.
