1849 Riograndense Chamber of Deputies election (RRG)

The 1849 Riograndense Chamber of Deputies election was held on April 1, 1849. The first election since the official creation of the National and Radical parties, this election was demonstrated the inadequacy of the country's block voting system as all of the National Party's candidates were elected, giving them a 22 seats out of 25 with 48% of the popular vote.

This was the last straw for the liberals as they found themselves sidelined from political life despite their impressive share of the vote. This election marked the point where the liberal hopes turned to a military coup as their prospects of winning a plurality among the country's wealthy Catholic electorate was slim. The 1849 election is therefore credited with being the event that directly led to the 1851 Riograndense military coup and the end of the First Republic.
