Answer:
Uruguay
As you'd expect from the name, the viceroyalty included the countries which bordered the River Plate, with the major exception of Brazil, since this was a Portuguese colony at the time. One of the major reasons for its establishment was the threat from Portugal to the north and that of other colonial Europeans, such as Great Britain. It lasted a relatively short time, With Spain distracted by the Napoleonic Wars and the constituent countries fighting for independence, the formal dissolution came in 1814. Argentina's War of Independence began in1810, continuing until 1818, although the country's independence dates from 1816.
Brazil was excluded as an 'enemy' territory, Venezuela was too far north and Peru too far west to be part of the viceroyalty.
