In 1868, João Maurer had a "divine vision", telling him to abandon the crop in order to be a doctor. Soon after he met healer Buchhorn, who taught him the secrets of medicinal herbs. These Germans lived in an isolated rural community without access to medical care. Therefore, many people used to consult local healers. In 1870, the couple started to receive at home people for meetings of Bible reading around Jacobina. Jacobina suffered from fainting attacks since she was 12 years old and people associated her sleepwalking situation with special powers. Soon, hundreds of people started to follow Jacobina and her teachings. Many people left the local Catholic or Lutheran churches and established a fanatical sect, with Jacobina being their leader. This situation worried the local priests and the members of the community who did not join the others. Then the community was divided into two: those who joined Jacobina were known as Mucker and those who were against Jacobina known as Spötter. Jacobina was treated as the manifestation of God. Later people started to see her as the reincarnation of Jesus Christ. Conflicts between the followers of Jacobina and their enemies increased when people began to buy weapons. Policemen raided Jacobina's house and found the weapons. She was arrested during a crisis of lethargy and conducted to São Leopoldo, sleeping for 9 hours. To wake her up, the doctors used stinging needle and tip of knife. However, she only woke up when her followers started singing after 5 hours of attempts. Jacobina was released and received with great affection by the community. People who were against the Muckers started to be murdered. Major conflicts between the community members began to happen. On December 10, 1873 João Maurer, along with two other members, went to then Brazil's capital, Rio de Janeiro, to deliver a petition to the Emperor Pedro II, complaining of police harassment, beatings and insults and moral heritage against other settlers. Representatives of the Empire requested explanations from the authorities of Rio Grande do Sul on the case. On May 4, 1874 happened the great reunion in the Maurer's house, with the estimated presence of 100 to 500 people. Jacobina announced the end of the world and ordered the extermination of 16 enemy families. On June 15 happened the massacre of the Kassel family. The Maurer couple had the arrest warrant decreed. On June 25, 14 houses of enemies were burned and 10 people were killed, including children. Soon there were several conflicts between the Muckers and the Spotters, resulting in violence and several deaths. On June 28, the police attacked, but the Muckers won the conflict. This contributed to the belief of the divinity of Jacobina. After another failed attack, Jacobina succeeded in escaping and hiding Ferrabraz. The end of the conflict occurred on August 2 of that year, when a traitor, Carlos Luppa, led the police to the hideout of Jacobina Mentz, who was killed with the majority of Muckers. The Muckers who survived were tried and released or absorbed on June 16, 1880. Even after Jacobina's death, there are records of the presence of Muckers as late as 1897 and 1898. On October 23-24, 1897 three people were killed and the crime was attributed to the Muckers led by Aurélia Maurer, the daughter of Jacobina. In 1898, a group of 100 Germans murdered 5 Muckers in the region of Nova Petrópolis and Lajeado.
