Leopold II was Grand Duke of Tuscany from 1824 to 1859. He married twice; first to Maria Anna of Saxony, and after her death in 1832, to Maria Antonia of the Two-Sicilies. By the latter, he begat his eventual successor, Ferdinand. Leopold was recognised contemporarily as a liberal monarch, authorising the Tuscan Constitution of 1848, and allowing a degree of press freedom.

Lago di Bientina, also known as Lago di Sesto, was a lake in Tuscany, Italy. Located to the north of the town of Bientina, between Lucca and Pisa, the lake was historically subject to numerous efforts at drainage due to its tendency to flood. Early attempts at canal-building and drainage in the 16th century were hampered by the lake's connection with the Arno River, which often led to backflow and even increased flooding.
