Presidential elections were held for the first time in the United Provinces of the Río de la Plata on 27 February 1826,[1] during the Cisplatine War. The elections were indirectly, with members of Congress forming an electoral college. Bernardino Rivadavia was the only candidate, and was elected with 35 votes in favor and three against. He was and sworn in the following day. His appointment, because a national constitution had not yet been sanctioned or approved, was questioned and viewed with suspicion by several provinces.[2]
