Giovanni Lanza, an Italian statesman, born at Vignale, Piedmont, in 1815. He became a member of the Sardinian chamber in 1848, and of Cavour's cabinet as minister of education in 1855, and of finance in 1858. He withdrew with Cavour in 1859, and was repeatedly president of the Sardinian chamber and the Italian parliament. In 1864-'5 he was minister of the interior under Lamarmora, and he executed the transfer of the capital of Italy to Florence. In 1867 he was again president of the parliament, but resigned in consequence of his objections to the financial measures of the government. His reelection to the presidency in 1869 occasioned the resignation of the Menabrea cabinet, and the king called upon him to form a new one, in which he took the portfolio of the interior. The transfer of the capital to Rome, July 1, 1871, took place under his administration, and he projected beneficial financial measures. His cabinet, resigning June 26, 1873, was succeeded, after a protracted crisis, by that of Minghetti.
