Catholic religious orders that participated and supported the exploration, evangelizing and pacifying, were mostly Dominicans, Carmelites, Franciscans and Jesuits, for example Francis Xavier, Bartolomé de Las Casas, Eusebio Kino, Juan de Palafox y Mendoza or Gaspar da Cruz. In 1536, Dominican friar Bartolomé de las Casas went to Oaxaca to participate in a series of discussions and debates among the Bishops of the Dominican and Franciscan orders. The two orders had very different approaches to the conversion of the Indians. The Franciscans used a method of mass conversion, sometimes baptizing many thousands of Indians in a day. This method was championed by prominent Franciscans such as Toribio de Benavente.
