Urbano Pio Francesco Rattazzi (; 29 June 18085 June 1873) was an Italian politician and statesman.
Personal life
He was born in Alessandria, Piedmont. He studied law at Turin, and in 1838 began his practice, which met with marked success at the capital and Casale. His wife, Laetitia Marie Wyse Bonaparte, whom he married in 1863, was a noted French novelist and a grandniece of Emperor Napoleon I.
He left the Democrats for the Moderate Liberals, and formed the group of the center-left. This party formed a coalition with the center-right headed by Cavour. This coalition was known as the connubio, i.e. the union of the moderate men of the Right and of the Left, and brought about the fall of the d'Azeglio cabinet in November 1852 and the organization of a new ministry by Cavour. Rattazzi gave up a Parliament presidency in 1853 to become Minister of Justice and later Minister of the Interior. As Minister of the Interior, he carried a number of measures of reform, including that for the suppression of certain of the monastic orders, partial secularization of church property, and restricting the influence of the religious associations. This precipitated a bitter struggle with the Clerical party. During a momentary reaction of public opinion he resigned office in 1858, but again entered the cabinet under La Marmora in 1859 as Minister of the Interior.
