Duke of Lorraine in the context of Stanisław Leszczyński

John II of Anjou (Nancy, August 2, 1426 – December 16, 1470, Barcelona) was Duke of Lorraine from 1453 to his death. He was the son of René of Anjou and Isabella, Duchess of Lorraine. He was married to Marie de Bourbon, daughter of Charles I, Duke of Bourbon.

René II (2 May 1451 – 10 December 1508) was Count of Vaudémont from 1470, Duke of Lorraine from 1473, and Duke of Bar from 1483 to 1508. He claimed the crown of the Kingdom of Naples and the County of Provence as the Duke of Calabria 1480–1493 and as King of Naples and Jerusalem 1493–1508. He succeeded his uncle John of Vaudémont as Count of Harcourt in 1473, exchanging it for the county of Aumale in 1495. He succeeded as Count of Guise in 1504.

René I of Anjou (Italian: Renato; Occitan: Rainièr; 16 January 1409 – 10 July 1480) was Duke of Anjou and Count of Provence from 1434 to 1480, who also reigned as King of Naples from 1435 to 1442 (then deposed). Having spent his last years in Aix-en-Provence, he is known in France as the Good King René (Occitan: Rei Rainièr lo Bòn; French: Le bon roi René).

René was a member of the House of Valois-Anjou, a cadet branch of the French royal house, and the great-grandson of John II of France. He was a prince of the blood, and for most of his adult life also the brother-in-law of the reigning king Charles VII of France. Other than the aforementioned titles, he was also Duke of Bar from the 1420s onwards and Duke of Lorraine from 1431 to 1453.

Stanisław I Leszczyński (Stanisław Bogusław; 20 October 1677 – 23 February 1766), also Anglicized and Latinized as Stanislaus I, was twice King of Poland and Grand Duke of Lithuania, and at various times Prince of Deux-Ponts, Duke of Bar and Duke of Lorraine.

During the Great Northern War, multiple candidates had emerged after the death of John III Sobieski for the elective kingship of Poland (which also included the Grand Duchy of Lithuania as part of the Poland-Lithuanian Commonwealth). Backed by powerful neighbors in Russia and Austria, the Sejm elected Augustus the Strong, Elector of Saxony to succeed John III in 1697 as August II. Russia's primary antagonist in the Great Northern War, Sweden had supported Stanisław Leszczyński for the throne, and after defeating a combined army of Saxon and Polish-Lithuanian forces, deposed August II and installed Leszczyński as Stanisław I in 1704.

The Place Stanislas is a large pedestrianised square in the French city of Nancy, in the Lorraine historic region. Built between 1752 and 1756 on the orders of Stanislaus I, former King of Poland and Grand Duke of Lithuania, then Duke of Lorraine, the square is one of the oldest examples of an architecturally consistent monumental public square and is an excellent example of 18th-century urban architecture. Since 1983, the architectural ensemble comprising the Place Stanislas, the extension of its axis, the Place de la Carrière and the Place d'Alliance, has been a UNESCO World Heritage Site.

Theobald I (French: Thiébaud or Thiébaut) (c. 1191 – 17 February 1220) was the duke of Lorraine from 1213 to his death. He was the son and successor of Frederick II and Agnes of Bar.

Antoine (4 June 1489 – 14 June 1544), known as the Good, was Duke of Lorraine from 1508 until his death in 1544. Raised at the French court, Antoine would campaign in Italy twice: once under Louis XII and the other with Francis I. During the German Peasants' War, he would defeat two armies while retaking Saverne and Sélestat. Antoine succeeded in freeing Lorraine from the Holy Roman Empire with the Treaty of Nuremberg of 1542. In 1544, while Antoine suffered from an illness, the Duchy of Lorraine was invaded by Emperor Charles V's army on their way to attack France. Fleeing the Imperial armies, Antoine was taken to Bar-le-Duc where he died.

Leopold the Good (11 September 1679 – 27 March 1729) was Duke of Lorraine and Bar from 1690 to his death. Through his son Francis Stephen, he is the direct male ancestor of all rulers of the Habsburg-Lorraine dynasty, including all Emperors of Austria.
