Although there was a General Congress intended to draft a constitution, the beginning of the War with Brazil led to the immediate establishment of the office of President of Argentina; with Rivadavia being the first to be named to the post.

By 1814 the Spanish King Ferdinand VII had returned to the throne and started the Absolutist Restoration, which had grave consequences for the governments in the Americas.

Over the next five years, he exerted a strong influence, and focused heavily on improving the city of Buenos Aires, often at the expense of greater Argentina.

He founded the University of Buenos Aires, as well as the Theatre, Geology, and Medicine Academies and the continent's first museum of natural science.

The provincial bonds were sold in London through the Baring Brothers Bank, local and Buenos Aires-based British traders also acting as financial intermediaries.

A strong supporter of a powerful, centralized government in Argentina, Rivadavia often faced violent resistance from the opposition federalists.

His government had many problems, primarily an ongoing war with Brazil over territory in modern Uruguay and resistance from provincial authorities.

Faced with the rising power of the Federalist Party and with several provinces in open revolt, Rivadavia submitted his resignation on June 27, 1827.

At present they rest in a mausoleum located in the Plaza Miserere, in Buenos Aires, adjacent to Rivadavia Avenue, named in their honor.
