The Order of Saint Stanislaus (Polish: Order św. Stanisława, Russian: Орденъ Св. Станислава) was an Order in Polish-Lithuanian Commonwealth. The Order of St. Stanislaus originally existed between 1765 and 1917.
There are three or four Orders of Saint Stanislaus today. These different Orders and Grandmasters do not recognize each other as legitimate successors or revivals of the Order of Saint-Stanislaus.
Stanislaus II Augustus Poniatowski, King of Poland established the Order of the Knights of Saint Stanislaus, Bishop and Martyr on May 7, 1765 to honor the service to the King.
After the partition of Poland it was recognized in the Grand Duchy of Warsaw in 1807. Since 1815 in the Polish (Congress) Kingdom, the order, originally in a single class, was retained and divided into four classes. After the downfall of the November Uprising, the order was added to the awards system of the Russian Empire in 1832, where it remained until 1917. In 1918 Poland regained its independence as the Second Polish Republic, the order was not renewed and was replaced by the Order of Polonia Restituta.
