Andrés Guazurary

Andrés Guaçurary or Andrés Guazurarí, popularly known as Andresito was a caudillo of the province of Misiones, present-day Argentina, being governor of said province between 1811 and 1822. He was one of the first federal caudillos of the United Provinces of the Río de la Plata and the only one of fully indigenous origin.

He was born in the misión of Santo Tomé, Corrientes or São Borja to a Guarani family. He was taken as a foster child by José Gervasio Artigas who allowed him to sign as Andrés Artigas, to avoid being excluded by his Guarani origins.
