GUERRAZZI, FRANCESCO DOMENICO (1804 1873), Italian publicist and patriot, born at Leghorn on Aug. 12, 1804, was educated for the law at Pisa, and began to practise in his native place. Mazzini made his acquaintance, and with Carlo Bini they started a paper, the Indicatore, at Leghorn in 1829, which was quickly suppressed. Guerrazzi himself had to endure several terms of imprisonment for his activity in the cause of Young Italy, and his most famous novel Assidio di Firenze (1834) was written in prison. He was the most powerful Liberal leader at Leghorn, and in 1848 became a minister, with some idea of exercising a moderating influence in the difficulties with the grand duke of Tuscany. In 1849, when the latter fled, he was first one of the triumvirate with Mazzini and Montanelli, and then dictator, but on the restoration he was arrested and imprisoned for three years. His Apologia was published in 1852. He was exiled to Corsica. On his return he became a deputy at Turin (1862-187o). He died at Leghorn on the 25th of September 1873. His works include the novels Isabella Orsini (1845) and Beatrice Cenci (1854). His Opere were collected at Milan (1868).
