Here is a useful resource for anyone interested in understanding the organization of civic life in Argentina and the organization of the Argentine Government. The National Constitution of the Argentine Nation was adopted in 1853, and was amended and revised five times since then; the last amendment took place in 1994.

The Argentine National Constitution was drafted in Spanish, the official language of the country. Here we have an official translation from Spanish into English, for reference purposes for non-Spanish speakers, which can be found in the official web page of the Argentine National Congress: http://www.congreso.gob.ar/nationalConstitution.php.  This web page shows access to the text of the National Constitution divided in different links for each part and chapter of the document.

Another official web site of Argentina, the Library of the Ministry of Justice and Human Rights, shows the same English translation in a full pdf file: http://www.biblioteca.jus.gov.ar/argentina-constitution.pdf

The Constitution defines Argentina as a federal republic. The government system of Argentina is based on the division of powers between the federal government and local governments. The federal government is made up of three branches: legislative, executive and judicial. The Argentine legal system belongs to the civil law tradition.

This is the Preamble of the Argentine Constitution, a clear, strong and decided declaration of self-determination from the people of Argentina:
