Rodríguez de Francia established new laws that greatly reduced the powers of the Catholic church (Catholicism was then an established state religion) and the cabinet, forbade colonial citizens from marrying one another and allowed them to marry only blacks, mulattoes or natives, in order to break the power of colonial-era elites and to create a mixed-race or mestizo society. He cut off relations between Paraguay and the rest of South America. Because of Francia's restrictions of freedom, Fulgencio Yegros and several other Independence-era leaders in 1820 planned a ''coup d’état'' against Francia, who discovered the plot and had its leaders either executed or imprisoned for life.
