Franciszek Smuglewicz, or Pranciškus Smuglevičius, 6 October 1745 – 18 September 1807) was a Polish-Lithuanian draughtsman and painter. Smuglewicz is considered a progenitor of Lithuanian art in the modern era. Some consider him as a spiritual father of Jan Matejko's school of painting. His brother was Antoni Smuglewicz.
Franciszek Smuglewicz was born in Warsaw into a Polish-Lithuanian family. His father, Łukasz Smuglewicz, also a painter, had moved to Warsaw from the Lithuanian province of Samogitia. His mother, Regina Olesińska, was the niece of painter Szymon Czechowicz. In 1763 Franciszek journeyed to Rome, where he began the study of fine arts under the tutorship of Anton von Maron. He stayed in Rome for 21 years, where he embraced the Neo-Classical style.
In 1765 he received a royal scholarship from the King of Poland and the Grand Duke of Lithuania Stanisław August Poniatowski and was admitted into the Saint Lucas Academy. As a colleague of Vincenzo Brenna he participated in cataloging artifacts from Nero's Domus Aurea. In 1784 he returned to Warsaw, where he founded his own school of fine arts, one of the predecessors of the modern Academy of Fine Arts.
A classicist, but under strong influence of the Polish baroque, Smuglewicz became a notable representative of historical paintings, a genre that dominated the fine arts of Poland throughout the 19th century. Around 1790 he started working on a series of sketches and lithographies inspired by Adam Naruszewicz's History of the Polish Nation. Although never finished, this series gained him much popularity.
