One of the conditions stipulated in it was one in which each rehue of the Mapuche would be left under the vigilance of a Spaniard with the title of capitán de amigos (Captain of Friends), who were to watch over them to see the terms of the agreement were kept.
These civil servants acts were put under the inspection of a superior commander, the comisionado de las naciones (Commissioner of Nations).
In 1694 the toqui Millalpal and the Mapuche were incited to revolt by the unauthorized activities of Antonio Pedreros, the Commissioner of Nations.
The Parliament of Choque-choque held by governor Tomás Marín de Poveda, 1st Marquis of Cañada Hermosa managed to end the revolt.
However the abuses and activities of the capitans de amigos eventually triggered the Mapuche Uprising of 1723 by the toqui Vilumilla.
