Sosnowiec is an industrial city county in the Dąbrowa Basin of southern Poland, in the Silesian Voivodeship, which is also part of the Silesian Metropolis municipal association. Located in the eastern part of the Upper Silesian Industrial Region, Sosnowiec is one of the cities of the Katowice urban area, which is a conurbation with the overall population of 2.7 million people; as well as the greater Upper Silesian metropolitan area populated by about 5.3 million people. The population of the city is 194,818 as of December 2021. Geography It is believed that the name Sosnowiec originates from the Polish word sosna, referring to the pine forests growing in the area prior to 1830. The village was originally known as Sosnowice. Other variations of the name include Sosnowietz, Sosnowitz, Sosnovitz (Yiddish), Sosnovyts, Sosnowyts, Sosnovytz, Sosnowytz, and Sosnovetz. There are five other smaller settlements in Poland also called Sosnowiec, located in the Kielce Voivodship, Łódź Voivodship, and Opole Voivodship. Sosnowiec serves as one of the administrative centres of the geographical and historical area of southern Poland known as the Zagłębie Dąbrowskie (the Dąbrowa Basin). It lies within the historic Lesser Poland region near the border with Silesia. It is located about north-east to the centre of Katowice and north-west of Kraków, situated in the Silesian Upland on the rivers Brynica and Przemsza, a tributary of the Vistula. The full list of rivers includes Biała Przemsza as well as Czarna Przemsza, Brynica, Bobrek, and Potok Zagórski creek. The city is part of the Silesian Voivodeship since its formation in 1999. Previously (since 1945), it was part of Katowice Voivodeship, and before World War II, Sosnowiec belonged to Kielce Voivodeship. History The history of the city begins in 1902 when it was granted city rights after the merger a number of older settlements. However, the history of the village of Sosnowiec dates back to the year 1227, when it was mentioned for the first time. It was a small settlement in the Polish Duchy of Kraków, located in close vicinity of much larger and better-developed villages of Sielce and Zagórze (both are now districts of the city). Other districts are even older. Milowice was first mentioned in 1123 as Miley. Documents from 1228 already mention Milowice, Klimontów, and Zagórze. Furthermore, Milowice was placed on a 1561 map. As part of the Polish–Lithuanian Commonwealth, Sosnowiec belonged to Kraków Voivodeship in the larger Lesser Poland Province
