Page "Justo José de Urquiza" Paragraph 1

He was governor of Entre Ríos during the government of Juan Manuel de Rosas, governor of Buenos Aires with powers delegated from the other provinces.

Rosas presented a resignation to his charge frequently, but only as a political gesture, counting that the other governments would reject it.

However, in 1851, resentful of the economic and political dominance of Buenos Aires, Urquiza accepted Rosas resignation and resumed for Entre Rios the powers delegated in Buenos Aires.

Along with the resuming of international commerce without passing through the port of Buenos Aires, Urquiza replaced the " Death to the savage unitarians!

" slogan with " Death to the enemies of national organization!

", requesting the making of a national constitution that Rosas had long rejected.

Corrientes supported Urquiza's action, but Rosas and the other provinces condemned the " crazy, traitor, savage, unitarian " Urquiza.

Supported by Brazil and the Uruguayan liberals, he created the " Big Army " and forced Manuel Oribe to capitulate, ending the long siege of Montevideo in October 1851, and finally defeating Rosas on 3 February 1852 at the Battle of Caseros.

The other provinces that supported Rosas against Urquiza's pronunciation changed sides and supported his project of creating a National Constitution.
