Antonio de Montesinos (?–1545) was a Dominican friar attached to the Spanish conquest of the Americas and one of the earliest of the Dominican arrivals in the New World. He is best remembered for a sermon delivered on December 4, 1511, in which he made a blistering attack on the colonists who had enslaved the people of the Caribbean. For his efforts, he was run out of Hispaniola, but he and his fellow Dominicans were eventually able to convince the king of the moral correctness of their point of view, thus paving the way for later laws that protected native rights in Spanish lands.

Early Life

Very little is known about Antonio de Montesinos before his famous sermon. He likely studied at the University of Salamanca before electing to join the Dominican order. In August 1510, he was one of the first six Dominican friars to arrive in the New World, landing on the island of Hispaniola, which today is politically divided between Haiti and the Dominican Republic. More clergy would come the following year, which brought the total number of Dominican friars in Santo Domingo to about 20. These particular Dominicans were from a reformist sect and were appalled at what they saw.

By the time the Dominicans arrived on the Island of Hispaniola, the native population had been decimated and was in serious decline. All of the native leaders had been killed, and the remaining Indigenous people were enslaved and given away to colonists. A nobleman arriving with his wife could expect to be given 80 enslaved natives; a soldier could expect 60. Governor Diego Columbus (the son of Christopher Columbus) authorized slaving raids on neighboring islands, and enslaved Africans had been brought in to work the mines. These enslaved people, living in misery and struggling with new diseases, languages, and culture, died by the score. The colonists, oddly, seemed almost oblivious to this ghastly scene.

The Sermon

On December 4, 1511, Montesinos announced that the topic of his sermon would be based on Matthew 3:3: “I am a voice crying in the wilderness.” To a packed house, Montesinos ranted about the horrors he had seen. “Tell me, by what right or by what interpretation of justice do you keep these Indians in such a cruel and horrible servitude? By what authority have you waged such detestable wars against people who were once living so quietly and peacefully in their own land?” Montesinos continued, implying that the souls of any and all who enslaved people on Hispaniola were damned.

The colonists were stunned and outraged. Governor Columbus, responding to the petitions of the colonists, asked the Dominicans to punish Montesinos and retract all that he had said. The Dominicans refused and took things even further, informing Columbus that Montesinos spoke for all of them. The next week, Montesinos spoke again, and many settlers turned out, expecting him to apologize. Instead, he re-stated what he had before, and further informed the colonists that he and his fellow Dominicans would no longer hear confessions from enslaver colonists.

The Hispaniola Dominicans were (gently) rebuked by the head of their order in Spain, but they continued to hold fast to their principles. Finally, King Fernando had to settle the matter. Montesinos traveled to Spain with Franciscan friar Alonso de Espinal, who represented the pro-enslavement point of view. Fernando allowed Montesinos to speak freely and was aghast at what he heard. He summoned a group of theologians and legal experts to consider the matter, and they met several times in 1512. The end results of these meetings were the 1512 Laws of Burgos, which guaranteed certain basic rights to New World natives living in Spanish lands.

Montesinos' defense of the Caribbean people was published in 1516 as "Informatio juridica in Indorum defensionem."

The Chiribichi Incident

In 1513, the Dominicans persuaded King Fernando to allow them to go to the mainland to peacefully convert the natives there. Montesinos was supposed to lead the mission, but he became ill and the task fell to Francisco de Córdoba and lay brother Juan Garcés. The Dominicans set up in the Chiribichi Valley in present-day Venezuela, where they were well-received by local chieftain “Alonso” who had been baptized years before. According to the royal grant, enslavers and settlers were to give the Dominicans a wide berth.

A few months later, however, Gómez de Ribera, a mid-level but well-connected colonial bureaucrat, went plundering and looking for people in enslave. He visited the settlement and invited “Alonso,” his wife, and several more members of the tribe on board his ship. When the natives were on board, Ribera’s men raised anchor and set sail for Hispaniola, leaving the two bewildered missionaries behind with the enraged natives. Alonso and the others were split up and enslaved once Ribera returned to Santo Domingo.

The two missionaries sent word that they were now hostages and would be killed if Alonso and the others were not returned. Montesinos led a frantic effort to track down and return Alonso and the others, but failed: After four months, the two missionaries were killed. Ribera, meanwhile, was protected by a relative, who happened to be an important judge.

An inquest into the incident was opened and colonial officials reached the extremely bizarre conclusion that since the missionaries had been executed, the leaders of the tribe—i.e. Alonso and the others—were obviously hostiles and could, therefore, continue to be enslaved. In addition, it was said that the Dominicans were themselves at fault for being in such unsavory company in the first place.

Exploits on the Mainland

There is evidence to suggest that Montesinos accompanied the expedition of Lucas Vázquez de Ayllón, which set out with some 600 colonists from Santo Domingo in 1526. They founded a settlement in present-day South Carolina named San Miguel de Guadalupe. The settlement lasted only three months, as many became ill and died and local natives repeatedly attacked them. When Vázquez died, the remaining colonists returned to Santo Domingo.

In 1528, Montesinos went to Venezuela with a mission along with other Dominicans. Little is known about the rest of his life. According to a note in the record of St. Stephen at Salamanca, he died in the West Indies as a martyr sometime around 1545.


Although Montesinos led a long life in which he continually struggled for better conditions for New World natives, he will forever be known mostly for that one blistering sermon delivered in 1511. It was his courage in saying what many had been silently thinking that changed the course of Indigenous rights in the Spanish territories. While he did not question the right of the Spanish government to expand its empire into the New World or its means of doing so, he did accuse the colonists of abuse of power. In the short term, it failed to alleviate anything and garnered him enemies. Ultimately, however, his sermon ignited a fierce debate over native rights, identity, and nature that was still raging 100 years later.

In the audience that day in 1511 was Bartolomé de Las Casas, himself an enslaver at the time. The words of Montesinos were a revelation to him, and by 1514 he had divested himself of all of the people he enslaved, believing that he would not go to Heaven if he kept them. Las Casas eventually went on to become the great Defender of the native population and did more than any man to ensure their fair treatment.
