Anadyr (; Chukchi: , Kagyrgyn, ; Southern Chukchi: Въэӈын, V"èňyn) is a port town and the administrative center of Chukotka Autonomous Okrug, Russia, located at the mouth of the Anadyr River at the tip of a peninsula that protrudes into Anadyrsky Liman. Anadyr is the easternmost town in Russia; more easterly settlements, such as Provideniya and Uelen, do not have town status. It was previously known as Novo–Mariinsk (until 1923). Population: History Early history Although the town itself has only been in existence for just over a century, the origins of the name Anadyr are much older. The name initially derives from the Yukaghir word "any-an" meaning "river". When Semyon Dezhnev met Yukaghir people in the area, the indigenous name was corrupted to form "Onandyr", later Anadyrsk, the name of the ostrog (fort) upstream of the present-day settlement, from which the current name is derived. The ostrog was the only Russian settlement east of the Kolyma River on the Chukotka Peninsula for most of the 18th century, though this original settlement was situated further up the Anadyr River, nearer to Markovo than the site of the current town. Pyotr Baranov (brother of Alexander Andreyevich Baranov) established a trading post near the present town site in the early 19th century. The Chukchi settled around it and formed the village of Vyon in 1830. The present settlement was founded in 1889 as Novo–Mariinsk by L. F. Grinevetsky, who sailed into the Anadyrsky Liman on July 9, 1889. The town's first building was completed twelve days later and as it was the name-day of Tsaritsa Maria Feodorovna the town was named Mariinsk. Since this was not the first time that a town had been named Mariinsk in Russia, the name was swiftly changed to Novo–Mariinsk. Early 20th century The Kamchatka Revkom sent the first Bolsheviks—Mikhail Mandrikov and Avgust Berzin—to Anadyr to set up an underground organization to undermine and eventually overthrow the resident White Army forces stationed in the town. These two, along with a small group of other Russian immigrants and a handful of Chuvans, established the First Revolutionary Committee of Chukotka. Their presence initially went undetected, although it did arouse suspicion. However, just before they were about to be discovered by the resident White Army troops, they launched an attack against them on the night of December 16, 1919. They intended to free the local indigenous people from their debts to
