Leopold II, 1747–92, Holy Roman emperor (1790–92), king of Bohemia and Hungary (1790–92), as Leopold I grand duke of Tuscany (1765–90), third son of Maria Theresa. Succeeding his father, Holy Roman Emperor Francis I, in Tuscany, Leopold reorganized the Tuscan government, abolished torture and the death penalty, equalized taxation, and sought to gain control over the church. When Leopold succeeded (1790) his brother Joseph II as emperor and as ruler of the Hapsburg lands, he took over a nearly disrupted state. To pacify his subjects in the Austrian Netherlands (see Netherlands, Austrian and Spanish), in Hungary, and in Bohemia, he repealed most of Joseph's reforms. Unlike Joseph, he had himself crowned king at Pozsony in Hungary (now Bratislava) and at Prague in Bohemia; he was the last crowned king of Bohemia. Having reached an agreement (1790) with Frederick William II of Prussia, who wished to prevent Austrian expansion in the east and was about to side with the Ottoman Empire (Turkey) in its war against Russia and Austria, Leopold abandoned his alliance with the Russian czarina, Catherine II. He concluded a separate peace treaty at Sistova (1791) with Turkey by which the pre-war borders were substantially restored. Leopold's troops marched into the Austrian Netherlands and suppressed the Belgian insurrection in 1790. Although he hoped to avoid war with revolutionary France, Leopold instigated (1791) the Declaration of Pillnitz, by which the emperor and the king of Prussia stated that if all other European powers would join them, they were prepared to restore Louis XVI to his lawful powers by force. Contrary to his expectations, this declaration was a basic cause of the outbreak of the French Revolutionary Wars a few weeks after Leopold's death. Leopold was succeeded by his son, Francis II. Leopold II is generally considered a ruler of outstanding diplomatic and administrative abilities.
