after a two-hour speech to the Bolshevik Central Committee during which, visibly quite ill, he violently denounced the United Opposition directed by Leon Trotsky, Grigory Zinoviev and Lev Kamenev. Upon hearing of his death, Joseph Stalin eulogized Dzerzhinsky as "a devout knight of the proletariat". Dzerzhinsky was buried in the Kremlin Wall Necropolis. Today his grave is one of the twelve individual tombs located between the Lenin Mausoleum and the Kremlin wall. Dzerzhinsky was succeeded as chairman of the OGPU by Vyacheslav Menzhinsky. Dzierżyńszczyzna, one of the two Polish Autonomous Districts in the Soviet Union, was named to commemorate Dzerzhinsky. Located in Belarus, near Minsk and close to the Soviet-Polish border of the time, it was created on 15 March 1932, with the capital at Dzyarzhynsk (In Russian Dzerzhynsk, formerly known as Kojdanów), not far from the family estate. (The Dzerzhinsky estate itself remained inside Poland from 1921 to 1939.) The district was disbanded in 1935 at the onset of the Great Purge, and most of its administration was executed. Dzyarzhynskaya Hara (the highest point in Belarus), located near Dzyarzhynsk was named after Dzerzhinsky in 1958. His name and image were used widely throughout the KGB and the Soviet Union and other socialist countries; there were several places named after him. In Russia, there is the city of Dzerzhinsk, a village of Dzerzhinsk, and three other cities called Dzerzhinskiy; in other former Soviet republics, there was a city named for him in Armenia and the aforementioned Dzyarzhynsk in Belarus. To comply with decommunization laws the Ukrainian cities Dzerzhynsk and Dniprodzerzhynsk were renamed Toretsk and Kamianske in February and May 2016. A Ukrainian village in the Zhytomyr Oblast was also named Dzerzhinsk until 2005, when it was renamed to Romaniv. The Dzerzhinskiy Tractor Works in Stalingrad were named in his honor and became a scene of bitter fighting during the Second World War. The FED camera, produced from 1934 to around 1996, is named for him, as was the FD class steam locomotive. During the Communist era (1945-1989) in Poland, Dzerzhinsky was celebrated as a socialist hero. In 1951, a large-scale statue of Dzerzhinsky was designed by Zbigniew Dunajewski and erected in the northern side of Bank Square in Warsaw. The square bore Dzerzhinsky's name () until 1989. The statue was toppled on 16 November 1989, one of the many Soviet-era symbols removed that year to mark the end of Communism
