Kaluga's most famous resident, the space travel pioneerKonstantin Tsiolkovsky, worked there as a school teacher from 1892 to 1935. TheTsiolkovsky State Museum of the History of Cosmonautics in Kaluga is dedicated to his theoretical achievements and to their practical implementations for modern space research, hence the motto on the city'scoat of arms:Колыбель Космонавтики,Kolybélʹ kosmonávtiki ("The Cradle of Space-Exploration").
Kaluga, founded in the mid-14th century as a border fortress on the southwestern borders of theGrand Duchy of Moscow, first appears in the historical record in chronicles in the 14th century asKoluga; the name comes from Old Russiankaluga is "bog, quagmire".[15] During the period of Tartar raids it was the western end of the Oka bank defense line. TheGreat stand on the Ugra River was fought just to the west. In the Middle Ages Kaluga was a minor settlement owned by the PrincesVorotynsky. Theancestral home of these princes lies southwest of the modern city.
Kaluga is connected to Moscow by a railway line and by the ancient roadway, the Kaluga Road (now partly within Moscow (as the Old Kaluga Highway), partly theA101 road).[17] This road offeredNapoleon his favored escape route from the Moscow trap in the fall of 1812. But GeneralKutuzov repelled Napoleon's advances in this direction and forced the retreating French army onto theOld Smolensk Road, previously devastated by the French during their invasion of Russia.
On several occasions during the Russian Empire Kaluga was the residence of political exiles and prisoners such as the last Crimean khanŞahin Giray (1786), the Kyrgyz sultan Arigazi-Abdul-Aziz (1828), the Georgian princessThecla (1834–1835), and the Avar leaderImam Shamil (1859–1868).[18]
TheGermanarmy briefly occupied Kaluga during the climacticBattle of Moscow, as part ofOperation Barbarossa. The city was under full or partial German occupation from October 12 to December 30, 1941. In 1944, the Soviet Government used its local military buildings to intern hundreds of Polish prisoners of war — soldiers of the Polish undergroundHome Army — whom the advancing Soviet front had arrested in the area aroundVilnius.
