Sacapulas is a town and municipality in the Guatemalan department of El Quiché.

Worried about the defection of the aj K’ub’ul family chief -who had taken his family away in order to look for fertile and, above all, pacific land-, the K’iche’ king sent a group of soldiers to control every single movement of them. He was afraid that the aj K'ub'ul would look for reinforcements from other ethnic group in the area to form a strong army and then attack the k'iche's. The warriors settled to the east of the aj K’ub’ul and since the latter had moved away to look for peace and tranquility, they were a very peaceful community. And that is exactly what the warriors inform the K’iche’ king, reassuring him by telling that he should not worry about the exiled group, as they were really peaceful.

As time went by, the k'iche' warriors realized that the aj K'ub'ul life was very different from the one they were used to have under the ruling of their king, as they simple worked on their land and crops and then enjoyed their families without having to worry about being invaded or called to fight in a war. Therefore, they went back to their place of origin, Tujalj (Sacapulas and Canillá)), but only to pick up their families and went on to settle a new community where they were once stationed to keep an eye on the aj K'ub'ul.

In the ten years after the fall of Zaculeu various Spanish expeditions crossed into the Sierra de los Cuchumatanes and engaged in the gradual and complex conquest of the Chuj and Q'anjob'al. The Spanish were attracted to the region in the hope of extracting gold, silver and other riches from the mountains but their remoteness, the difficult terrain and relatively low population made their conquest and exploitation extremely difficult. The population of the Cuchumatanes is estimated to have been 260,000 before European contact. By the time the Spanish physically arrived in the region this had collapsed to 150,000 because of the effects of the Old World diseases that had run ahead of them.

After the western portion of the Cuchumatanes fell to the Spanish, the Ixil and Uspantek Maya were sufficiently isolated to evade immediate Spanish attention. The Uspantek and the Ixil were allies and in 1529, four years after the conquest of Huehuetenango, Uspantek warriors were harassing Spanish forces and Uspantán was trying to foment rebellion among the K'iche'. Uspantek activity became sufficiently troublesome that the Spanish decided that military action was necessary. Gaspar Arias, magistrate of Guatemala, penetrated the eastern Cuchumatanes with sixty Spanish infantry and three hundred allied indigenous warriors. By early September he had imposed temporary Spanish authority over the Ixil towns of Chajul and Nebaj. The Spanish army then marched east toward Uspantán itself; Arias then received notice that the acting governor of Guatemala, Francisco de Orduña, had deposed him as magistrate. Arias handed command over to the inexperienced Pedro de Olmos and returned to confront de Orduña. Although his officers advised against it, Olmos launched a disastrous full-scale frontal assault on the city. As soon as the Spanish began their assault they were ambushed from the rear by more than two thousand Uspantek warriors. The Spanish forces were routed with heavy losses; many of their indigenous allies were slain, and many more were captured alive by the Uspantek warriors only to be sacrificed on the altar of their deity Exbalamquen. The survivors who managed to evade capture fought their way back to the Spanish garrison at Q'umarkaj.

A year later Francisco de Castellanos set out from Santiago de los Caballeros de Guatemala (by now relocated to Ciudad Vieja) on another expedition against the Ixil and Uspantek, leading eight corporals, thirty-two cavalry, forty Spanish infantry and several hundred allied indigenous warriors. The expedition rested at Chichicastenango and recruited further forces before marching seven leagues northwards to Sacapulas and climbed the steep southern slopes of the Cuchumatanes. On the upper slopes they clashed with a force of between four and five thousand Ixil warriors from Nebaj and nearby settlements. A lengthy battle followed during which the Spanish cavalry managed to outflank the Ixil army and forced them to retreat to their mountaintop fortress at Nebaj. The Spanish force besieged the city, and their indigenous allies managed to scale the walls, penetrate the stronghold and set it on fire. Many defending Ixil warriors withdrew to fight the fire, which allowed the Spanish to storm the entrance and break the defences. The victorious Spanish rounded up the surviving defenders and the next day Castellanos ordered them all to be branded as slaves as punishment for their resistance. The inhabitants of Chajul immediately capitulated to the Spanish as soon as news of the battle reached them. The Spanish continued east towards Uspantán to find it defended by ten thousand warriors, including forces from Cotzal, Cunén, Sacapulas and Verapaz. The Spaniards were barely able to organise a defence before the defending army attacked. Although heavily outnumbered, the deployment of Spanish cavalry and the firearms of the Spanish infantry eventually decided the battle. The Spanish overran Uspantán and again branded all surviving warriors as slaves. The surrounding towns also surrendered, and December 1530 marked the end of the military stage of the conquest of the Cuchumatanes.

On his second visit to Guatemala, in 1537, friar Bartolomé de las Casas, O.P. wanted to employ his new method of conversion based on two principles: 1) to preach the Gospel to all men and treat them as equals, and 2) to assert that conversion must be voluntary and based on knowledge and understanding of the Faith. It was important for Las Casas that this method be tested without meddling from secular colonists, so he chose a territory in the heart of Guatemala where there were no previous colonies and where the natives were considered fierce and war-like. Because it had not been possible to conquer the land by military means, the governor of Guatemala, Alonso de Maldonado, agreed to sign a contract promising that if the venture was successful he would not establish any new encomiendas in the area. Las Casas's group of friars established a Dominican presence in Rabinal, Sacapulas and Cobán, reaching as far as Chahal. Through the efforts of Las Casas' missionaries the so-called "Land of War" came to be called "Verapaz", "True Peace". Las Casas's strategy was to teach Christian songs to merchant Indian Christians who then ventured into the area. In this way he was successful in converting several native chiefs, among them those of Atitlán and Chichicastenango, and in building several churches in the territory named Alta Verapaz. These congregated a group of Christian Indians in the location of what is now the town of Rabinal. In 1538 Las Casas was recalled from his mission by Bishop Francisco Marroquín who wanted him to go to Mexico and then on to Spain in order to seek more Dominicans to assist in the mission.

After the conquest, the Spanish crown focused on the Catholic indoctrination of the natives. Human settlements founded by royal missionaries in the New World were called "Indian doctrines" or simply "doctrines". Originally, friars had only temporary missions: teach the Catholic faith to the natives, and then transfer the settlements to secular parishes, just like the ones that existed in Spain at the time; the friars were supposed to teach Spanish and Catholicism to the natives. And when the natives were ready, they could start living in parishes and contribute with mandatory tithing, just like the people in Spain.
