Passage:The history of Lubartów begins on May 29, 1543, when King Sigismund the Old allowed local nobleman Piotr Firlej to found a town called Lewartów (the original name comes from Lewart, the coat of arms of the Firlej family). The town became famous when it belonged to Mikołaj Firlej, the son of Piotr Firlej. In the late 16th century, it was one of centers of Calvinism in Lesser Poland, and Mikołaj Firlej invited here a number of skilled artisans from France, Germany and Holland, as well as cattle breeders. Lewartów frequently changed owners. In the early 18th century it belonged to the Sanguszko family, who rebuilt the palace, built two Baroque churches and tenement houses. Upon request of Paweł Karol Sanguszko, on November 22, 1744, King Augustus III of Poland changed the name of the town to Lubartów (in honor of Lubart - Liubartas, the son of Lithuanian Prince Gediminas; Sanguszko believed that Liubartas was the founder of his family). King Augustus granted a new coat of arms to the town. The 19th century was not lucky for Lubartów, as the town, which from 1815 to 1915 belonged to Russian-controlled Congress Poland, burned several times (1831, 1838, 1846). In 1866 it became the seat of a county, and slowly began modernization. By 1912 it had seven manufacturing enterprises, including mills and a brewery, in 1922, glassworks were opened.
