He was born in Alessandria (Piedmont). He studied law at Turin and in 1838 began working as a lawyer. He began his political career in 1848, when he was elected deputy of the Kingdom of Sardinia.
Urbano Rattazzi served as President of the Chamber of Deputies three times: twice in the Kingdom of Sardinia (from 11 May 1852 to 27 October 1853 and from 10 January 1859 to 21 January 1860) and once in the Kingdom of Italy (from 18 February 1861 to March 3 1862).
When Giuseppe Garibaldi tried to join Rome to Italy with a forceful action, Rattazzi ordered that he be arrested. However, "the hero of two worlds" escaped: consequently, Rattazzi was forced to resign and retire from political life.
Rattazzi was also several times Minister and deputy, both in the Kingdom of Sardinia and in the Kingdom of Italy.
