A good example of the common problems among South American countries soon after independence is the economic crisis that occurred in Brazil and Argentina.
On July 9, 1816, Argentina became independent. Due to the demand for provincial autonomy made by the federalists of the interior, and the opposition to this autonomy of the Unitarians of Buenos Aires, after the independence began the civil war. Only in 1853 did the Unitarians succeed in promulgating the First Constitution of Argentina. The Argentine civil war created a huge economic crisis that made it very difficult to establish the country as a sovereign nation. The effects of this crisis are seen to this day, and bring the suffering of many Argentines.
Brazil also experienced a severe economic crisis after becoming independent from Portugal. Unlike Argentina, the Brazilian economic crisis was not caused by a war but because Brazil, to become independent, had to bear the debts that Portugal had with England. Brazil became independent under the sign of stagnation. Before and after 1822, the scenario of crisis, poverty, and business downturn became dominant in national life.
At the political level, unlike in other South American countries, where the breakdown of colonial relations took place through bitter military confrontations, Brazil's political sovereignty resulted from a complex chain of negotiations involving Portugal and England. The purpose of the negotiations was the huge debt payments that Portugal had with the British crown.
