Lipetsk (), also romanized as Lipeck, is a city and the administrative center of Lipetsk Oblast, Russia, located on the banks of the Voronezh River in the Don basin, southeast of Moscow. Population: History Lipetsk was first mentioned in the 13th century chronicles. The name means "Linden city" and is cognate with Leipzig and Liepāja. In 1284, the city was destroyed by the Mongols. The foundation of the modern city dates back to 1703, when Peter the Great ordered construction of a cast iron factory in Lipetsk near the iron ore deposits for making artillery shells. On September 27, 1779, Lipetsk was granted town status. It became one of the principal towns of Tambov Governorate. In 1879, Lipetsk hosted a congress of members of Land and Liberty. After the Treaty of Rapallo (1922) until 1933, the much-reduced German Army (Reichswehr) of the Weimar Republic secretly contracted with Soviet authorities to operate a clandestine military aviation base and test facility near Lipetsk – circumventing prohibitions of the Versailles Treaty. The base enabled technical collaboration by the two powers whose separate defeats in World War I left them isolated in post-war Europe. This activity inside the U.S.S.R. took place away from the vigilant eyes of the victors. The Abwehr, The SS and German Army Group Centre penetrated part of this Lindenstadt Region in 1941-2. Administrative and municipal status Lipetsk is the administrative center of the oblast and, within the framework of administrative divisions, it also serves as the administrative center of Lipetsky District, even though it is not a part of it. As an administrative division, it is incorporated separately as Lipetsk City Under Oblast Jurisdiction—an administrative unit with a status equal to that of the districts. As a municipal division, Lipetsk City Under Oblast Jurisdiction is incorporated as Lipetsk Urban Okrug. Economy The principal industries of Lipetsk include ferrous metallurgy, machinery, metalworking, machine tools, engines, chemicals, food, and clothing.
