The Platine War and Constitution of 1852
With Urquiza’s demand laid before Rosas, he could accept the demands or he could refuse them. He chose the later knowing full well this spelled war, but such treason would not be accepted in Argentina. This refusal made everyone concerned in the neighboring countries. Another cycle of the civil war could easily spill over to their countries.
So both sides began to make preparations for the struggle that was to come. Both sides worked with more reactionary members in their government to increase the conscription size. Rosas would also encourage the countries research to be dedicated to military research in preparation for the conflict.
However, just as important for Rosas and Urquiza was the diplomatic offensive. Both knew that allies would be needed. They both made overturns to the allies of Argentina: Bolivia, Uruguay and the Rio Grande but also the other neighboring countries.
The Republic of Chile which had so far enjoyed uninterrupted peace since the end of their war with the Peru-Bolivian Confederation informed Rosas that they would remain neutral. The Empire of Brazil and the republic of Paraguay offered their support to Urquiza mainly in an effort to see Argentina weak. The republics of Bolivia, and the Rio Grande and Uruguay offered their support to Rosas.
On April 5th 1851 the war that everyone was preparing for broke out in the open and all the members of the army for both side would be called forth. However despite the allies both made, the war would be limited to just Rosas and Urquizia, which brought relief to Rosas and worry to Urquiza.
To make up for this, Urquiza would send his army directly to Buenos Aires. If the city could be captured then it would be a major coup for Urquiza and spell disaster for Rosas and might entice others to support Urquiza over Rosas directly.
Thus the Battle of Buenos Aires would begin on April 20th, the battle would be fought near the city. However though it looked for some time that Urquiza’s gambit was about to pay off when it looked like the battle started to go the way of Urquiza’s force however Rosas’ General Jose de la Plaza would rally his forces and deliver Rosas a decisive victory.
This victory would lead to the battle of Sancti Spirtu on July 5th 1851 where another decisive battle would be given thanks to the command of Angel Pacheco who uterly destroyed the army of Entre Rios that was sent to take the region. This meant that Entre Rios was open to the forces of Rosas.
So December 21st the capital city of Entre Rios, Parana, would be captured by the forces of Rosas. The fall of this city meant that the war was all but over. It would take several months to effectively end the rebellion by Justo Jose de Urquiza. However on March 11th 1852 the war came to an end. Urquiza and his main supporters would be tried and found guilty of treason against Argentina and executed for their actions.
With this victory Rosas had a chance that no one else had to effectively alter the nature of Argentina by himself. No one knew what framework Rosas was going to go with. Was he going to stay as a de facto presidential dictator, would he bring democracy to Argentina, would he follow in the footsteps of Napoleon and crown himself King, no one knew for sure though many had ideas as to what the future would bring.
In the end the May 10th Constitution would be arguably Rosas greatest Triumph. Political franchise was open up to all those whom were middle class and above. It established a republic in the framework similar to the United States of America, with its separation of power and checks and balances. Most importantly, a central part of the new Constitution was its federal character which was reflected in the country’s new official name – Federal Republic of Argentina. Though despite the checks and balances, power would still lay in the President. The president would be elected by direct popular vote every four years with the senate deciding on the president in case of a tie. The senate would be based on the population, with the provinces that have the more people having more senators. This would give quite a bit of power and influence to Buenos Aires to remain as the dominate province within the Republic.
Rosas whom during the civil wars had clamped down on Freedom of the press and used his secret police to keep control would reverse course with the constitution and establish the freedom of the press. The constitution would finally abolish slavery once and for all. As part of the constitution the flag of Argentina would be changed, the blue would be lightened to Azur blue and the Phrygian caps in the corners would be removed.

This would come as a shock to many within Argentina that expected Rosas to either keep power for himself or worse follow in the footsteps of Napoleon. Instead he established a new constitution that made Democracy come to Argentina. Where before people were decrying Rosas as a tyrant and liking him to Roman Emperors, now he was compared to the roman Cincinnatus and the American George Washington.
However, Rosas aimed to avoid the years of civil wars for good and to that end he achieved what many thought he could not, restore stability to Argentina. That was the goal inherent in the Constitution. Following in the footsteps of Napoleon or holding all power to himself would very likely continue the cycle of civil wars. He may be able to hold power, but would his successor in either scenario? Rosas believed they would not and thus one would need a new constitution to put an end to this cycle of civil war once and for all.
With the signing of the constitution, the first elections would be called for. Rosas appointed successor Nazario Benavídez whom had been one of Rosas loyal supporters, a top military man and governor of San Juan province. The sheer popularity for Rosas and his new constitution all but guaranteed that Nazario Benavídez would win the election. It also helped that Benavídez was respected by nearly everyone. Even Domingo Faustino Sarmiento, author of Facundo, whom remained a staunch liberal critic of Rosas respected Benavídez

However Rosas was able to secure one final victory for himself diplomatically before handing the future off to Nazario Benavídez. Due to the various civil wars going on in Argentina following independence, the Spanish government was unable to formally recognize Argentina’s independence. However, Rosas sent Mariano Severo Balcarce as a diplomat to Spain and successfully was able to sign the treaty of Madrid that established formal relations between Argentina and Spain.
