The article is a biographical sketch devoted to the figure of Prince Józef Poniatowski (1763–1813). It was created on the occasion of the 210th anniversary of the battle of Raszyn, which took place on April 19, 1809. During this battle Józef Poniatowski impressed both his soldiers and Austrian opponents with extraordinary bravery and heroism. In the same year he received the Grand Cross of the Legion of Honor, which was established by Napoleon Bonaparte. Poniatowski said without false modesty that “God has entrusted me with the honor of Poles, I will give him to God.” He was also prophetically saying that “You must die bravely”. He was born in Vienna and raised in a German-speaking environment. Pepi, as he was commonly called, became at the turn of the 18th and 19th centuries, along with Tadeusz Kościuszko, a hero of the Polish nation. In the presented article, especially the place deals with the issue of its extraordinary popularity in the history of the nation and the Polish state of the last two centuries. The symbol of this popularity is the fact that Prince Józef Poniatowski has long had a monument in Warsaw, and his uncle, King of Poland, Stanisław August Poniatowski, will probably never have one. The presented article was based on the most important scientific studies devoted to Poniatowski.
