The Polish Golden Age was the Renaissance period in Poland and the Grand Duchy of Lithuania, roughly corresponding to the period of rule of the King Władysław II Jagiełło (1386–1434) and Sigismund II Augustus, the last of the Jagiellonian Dynasty monarchs, until his death in 1572. Some historians argue that the Polish Golden Age continued into the mid-17th century, when the Polish–Lithuanian Commonwealth was ravaged by the Khmelnytsky Uprising (1648–57) and by the Swedish and Russian invasion. During its Golden Age, the Commonwealth became one of the largest kingdoms of Europe and at its peak stretched from modern-day Estonia in the north to Moldavia in the south and from Moscow in the east to Brandenburg in the west.

Polish is a West Slavic language of the Lechitic group within the Indo-European language family written in the Latin script. It is primarily spoken in Poland and serves as the official language of the country, as well as the language of the Polish diaspora around the world. In 2023, there were over 40.6 million Polish native speakers. It ranks as the sixth most-spoken among languages of the European Union. Polish is subdivided into regional dialects and maintains strict T–V distinction pronouns, honorifics, and various forms of formalities when addressing individuals.
