Wrocław (Polish: [ˈvrɔt͡swaf] ; German: Breslau [ˈbʁɛslaʊ] ; also known by other names) is a city in southwestern Poland, and the capital of the Lower Silesian Voivodeship. It is the largest city and historical capital of the region of Silesia. It lies on the banks of the Oder (Odra) River in the Silesian Lowlands. In 2025, the official population of Wrocław was 672,545, making it the third-largest city in Poland. The population of the Wrocław metropolitan area is around 1.25 million.
Wrocław is the historical capital of Silesia and Lower Silesia. The history of the city dates back over 1,000 years; throughout history it has been under Polish, Bohemian, Austrian, Prussian and German rule, until it became again part of Poland in 1945 immediately after World War II.
Wrocław is a university city with a student population of over 130,000, making it one of the most youth-oriented cities in the country. Wrocław has numerous historical landmarks, including the Main Market Square, Cathedral Island, Bridge of Love, Wrocław Opera, the National Museum and the Centennial Hall, which is listed as a UNESCO World Heritage Site. The Wrocław's dwarfs are a major tourist attraction and have become a symbol of Wrocław. The city is home to the Wrocław Zoo, the oldest zoological garden in Poland.
Wrocław is classified as a Sufficiency global city by GaWC. It was ranked 1st among all medium and small cities in the 2021 European Cities and Regions of the Future ranking by fDi Intelligence. The city is home to Śląsk Wrocław football club and hosted the 2012 European Football Championship. In 2016, the city was a European Capital of Culture and the World Book Capital, and hosted the Theatre Olympics and the European Film Awards. In 2017, the city was host to the World Games. In 2019, it was named a UNESCO City of Literature.
The origin of the city's name is debated. It was long believed that the city was named after Duke Vratislav I of Bohemia from the Czech Přemyslid dynasty, who was ruling between 915 and 921. This thesis is contradicted, however, by the fact that the Czechs only took control of the Wrocław gród around the year 945.
The earliest recorded mentions of the city's name, found in Thietmar's Chronicle (Wrotizla, Wordisclavia, Wortizlania, Vaurtizlau), written around the year 1000, indicate the phonetic form of the original name of the city as Wrocisław, derived from the Old Polish given name Wrocisław/Warcisław. According to researchers, this was the name of the city's founder, whom Edmund Małachowicz identified as a duke from the Włost family of Niemcza.
As a result of phonetic changes, the name was later shortened to Wrocław, first recorded in 1175 in the Latinized form Wrezlaw, and it became widespread in the 13th century. Also in the 12th century, a Czech-influenced and Latinized form, Vratislavia, began to appear. The city's first municipal seal was inscribed with Sigillum civitatis Wratislavie.
By the 15th century, the Early New High German variations of the name, Breslau, first began to be used. Despite the noticeable differences in spelling, the numerous German forms were still based on the original West Slavic name of the city, with the Vr- sound being replaced over time by Br-, and the suffix -slav replaced with -slau. These variations included Wrotizla, Vratizlau, Wratislau, Wrezlau, Breßlau or Bresslau among others. A Prussian description from 1819 mentions two names of the city – Polish and German – stating "Breslau (polnisch Wraclaw)".
In other languages, the city's name is: German: Breslau [ˈbʁɛslaʊ] ; Silesian German: Brassel; Yiddish: ברעסלוי, romanized: Bresloy; Silesian: Wrocław; modern Czech: Vratislav [ˈvracɪslaf]; Hungarian: Boroszló [ˈborosloː]; and Latin: Wratislavia or Vratislavia.
People born or resident in the city are known as "Wrocławians" or "Vratislavians" (Polish: wrocławianie). The now little-used German equivalent is "Breslauer".
In ancient times, there was a place called Budorigum at or near the site of Wrocław. It was already mapped on Claudius Ptolemy's map of AD 142–147. Settlements in the area existed from the 6th century onward during the migration period. The Ślężans, a West Slavic tribe, settled on the Oder river and erected a fortified gord on Ostrów Tumski.
Wrocław originated at the intersection of two trade routes, the Via Regia and the Amber Road. Archeological research conducted in the city indicates that it was founded around 940. In 985, Duke Mieszko I of Poland conquered Silesia, and constructed new fortifications on Ostrów. The town was mentioned by Thietmar explicitly in the year 1000 AD in connection with its promotion to an episcopal see during the Congress of Gniezno.
During Wrocław's early history, control over it changed hands between the Duchy of Bohemia (1038–1054), the Duchy of Poland and the Kingdom of Poland (985–1038 and 1054–1320). Following the fragmentation of the Kingdom of Poland, the Piast dynasty ruled the Duchy of Silesia. One of the most important events during this period was the foundation of the Diocese of Wrocław in 1000. Along with the Bishoprics of Kraków and Kołobrzeg, Wrocław was placed under the Archbishopric of Gniezno in Greater Poland, founded by Pope Sylvester II through the intercession of Polish duke (and later king) Bolesław I the Brave and Emperor Otto III, during the Gniezno Congress. In the years 1034–1038 the city was affected by the pagan reaction in Poland.
The city became a commercial centre and expanded to Wyspa Piasek (Sand Island), and then onto the left bank of the River Oder. Around 1000, the town had about 1,000 inhabitants. In 1109 during the Polish-German war, Prince Bolesław III Wrymouth defeated the King of Germany Henry V at the Battle of Hundsfeld, stopping the German advance into Poland.
The medieval chronicle, Gesta principum Polonorum (1112–1116) by Gallus Anonymus, named Wrocław, along with Kraków and Sandomierz, as one of three capitals of the Polish Kingdom. Also, the Tabula Rogeriana, a book written by the Arab geographer Muhammad al-Idrisi in 1154, describes Wrocław as one of the main Polish cities, alongside Kraków, Gniezno, Sieradz, Łęczyca and Santok. By 1139, a settlement belonging to Governor Piotr Włostowic (also known as Piotr Włast Dunin) was built, and another on the left bank of the River Oder, near the present site of the university. While the city was largely Polish, it also had communities of Bohemians (Czechs), Germans, Walloons and Jews.
In the 13th century, Wrocław was the political centre of the divided Polish Kingdom. In April 1241, during the first Mongol invasion of Poland, the left-bank part of the city was abandoned by its inhabitants and burnt down for strategic reasons. During the battles with the Mongols Wrocław Castle was successfully defended by Henry II the Pious. In 1245, in Wrocław, Franciscan friar Benedict of Poland, considered one of the first Polish explorers, joined Italian diplomat Giovanni da Pian del Carpine, on his journey to the seat of the Mongol Khan near Karakorum, the capital of the Mongol Empire, in what is considered the first such journey by Europeans.
After the Mongol invasion, the town was partly populated by German settlers who, in the ensuing centuries, gradually became its dominant population. The city, however, retained its multi-ethnic character, a reflection of its importance as a trading post on the junction of the Via Regia and the Amber Road. With the influx of settlers, the town expanded and in 1242 came under German town law. The city council used both Latin and German, and the early forms of the name Breslau, the German name of the city, appeared for the first time in its written records. Polish gradually ceased to be used in the town books, while it survived in the courts until 1337, when it was banned by the new rulers, the German-speaking House of Luxembourg.
The enlarged town covered around 60 hectares (150 acres), and the new main market square, surrounded by timber-frame houses, became the trade centre of the town. The original foundation, Ostrów Tumski, became its religious centre. The city gained Magdeburg rights in 1261. While the Polish Piast dynasty remained in control of the region, the city council's ability to govern independently had increased. The main source of prosperity was trade between Poland and Ruthenia and Western Europe, and crafts also contributed to the city's wealth. In 1274 prince Henry IV Probus gave the city its staple right. In the 13th century, two Polish monarchs were buried in Wrocław churches founded by them, Henry II the Pious in the St. Vincent church and Henryk IV Probus in the Holy Cross church.
