Domenico Giovanni Giuseppe Maria Lanza (15 February 1810 – 9 March 1882) was an Italian politician and the eighth prime minister of Italy from 1869 to 1873.
The association was concerned about reforming the political and economic spheres, as well as agriculture, and its identification with the cause of liberal nationalism—with the Risorgimento—was underlined at the September 1847 agrarian congress in Casale, when Lanza raised the cry of "Viva l'Italia libera ed indipendente!"
He attached himself to the party of Cavour and devoted his attention chiefly to questions of the economy and finance.
[4] He was minister of the interior (1864–1865) in the La Marmora cabinet, and arranged the transfer of the capital to Florence.
He maintained a resolute opposition to the financial policies of Menabrea, who resigned in 1869 when Lanza was elected for the second time as President of the Chamber.
