The Panzer I was a light tank produced in Germany in the 1930s. The name is short for the German Panzerkampfwagen I (“armored fighting vehicle mark I”), abbreviated PzKpfw I. The tank’s official German ordnance inventory designation was Sd.Kfz. 101 (“special purpose vehicle 101”).
Design of the Panzer I began in 1932 and mass production began in 1934. Intended only as a training tank to introduce the concept of armored warfare to the German Army, the Panzer I saw combat in Spain during the Spanish Civil War, in Poland, France, the Soviet Union and North Africa during the Second World War, and in China during the Second Sino-Japanese War. Experiences with the Panzer I during the Spanish Civil War helped shape the German Panzerwaffes’ invasion of Poland in 1939 and France in 1940. By 1941, the Panzer I chassis design was used as the basis of tank destroyers and assault guns.
