Jacob Frank was a famous religious leader in Poland. 
His movement grew through many different steps and changes. In the early 1750s, Frank began preaching his new revelations. He had traveled to places like Salonica and Smyrna in the Ottoman Empire. These trips helped him learn from other groups like the Dönmeh. After some trouble in Podolia, he moved to Iwania. There, he told his followers he received messages from Heaven. These messages eventually led his followers to change their faith. They moved from Judaism toward the Christian religion. 
The history of Frankism is full of big changes and many people. Frank was born around 1726, likely in Korołówka. His father was a follower of the Sabbatean movement. In 1759, a major event happened in the city of Lwów. Many Frankists decided to be baptized into the Roman Catholic Church. During one year, more than 500 people joined the Church in Lwów. Nearly a thousand more joined the following year. Frank himself was baptized in Lwów on September 17, 1759. He then went to Warsaw to be baptized again.
Life was not always easy for Frank and his followers. He was arrested in Warsaw in February 1760. A church court found him guilty of heresy. He spent thirteen years in the Jasna Góra Monastery in Częstochowa. This time in prison actually made him seem more important to his followers. They saw him as a martyr for his cause. After he was released in 1772, he lived in the town of Brno. He later moved to Germany and lived in Isenburg Castle. There, he used the title Baron of Offenbach. 
Frank's influence lasted long after his death in 1790. His daughter, Eve, took over as the leader of the sect. The Frankist group eventually spread out into many different families. Some of these families joined the middle class and the nobility. Some historians believe that famous Polish figures had Frankist roots. For example, some say the poet Adam Mickiewicz had ancestors from this group. The movement shows how religious ideas can change over many years. It also shows how people find new ways to express their faith.
Jacob Frank was a Polish-Jewish religious leader who founded a unique movement known as Frankism. 
Frank's religious doctrines were highly controversial and led to significant conflict with Jewish authorities. He taught a concept known as neo-Carpocratian "purification through transgression." This idea suggested that people could reach a state of holiness by deliberately breaking religious laws. He believed that embracing the "abyss" of sin was a way to hasten a messianic redemption. These teachings led to scandalous practices within the sect. These included ritualized acts and the violation of Jewish moral laws regarding modesty. Because of these heretical doctrines, the religious authorities of the Jewish community excommunicated Frank and his followers.
The development of Frankism was closely tied to the earlier messianic movement of Sabbatai Zevi. This mystical tradition emerged following socioeconomic changes among Jews in Poland, Lithuania, and Ruthenia. Between the late 17th and early 18th centuries, there were many outbreaks of Sabbatean followers in Eastern Poland. These groups were active in regions like Podolia and Galicia. Some followers practiced asceticism, which means they lived very simply and avoided pleasure. Others practiced sensuality and disregarded strict rules of modesty. In 1722, Polish rabbis attempted to place the "Sabbatean heresy" in herem, a form of religious excommunication, at an assembly in Lwów.
Jacob Frank's early life provided the foundation for his later leadership. He was likely born Jakub Lejbowicz in Korołówka, in the Podolia region of Eastern Poland. His father was a Sabbatean, which meant the movement's influence was present in his household. As a traveling merchant of textiles and precious stones, Frank visited Ottoman territories. During these travels, he earned the nickname "Frank," a name often given to Europeans in the East. While in the East, he became close to leaders of the Sabbatean movement. He spent time in centers like Salonica and Smyrna, where he learned from groups like the Dönmeh. These connections helped him develop the revelations he would later preach in Podolia.
A major turning point for the movement occurred in 1759 regarding the religion of the Frankists. Frank claimed his revelations required his followers to convert to Christianity. He viewed this as a necessary transition stage before a future religion, which he called "daas" or "knowledge," would be revealed. In 1759, negotiations took place between the Frankists and the Roman Catholic Church. While some Protestant missionaries also tried to influence them, many Frankists chose Catholicism. In Lwów, the baptism of the Frankists was a very large and solemn event. More than 500 individuals converted in Lwów during that first year. Nearly 1,000 more joined in the following year. 
Frank's personal life was marked by periods of imprisonment and high social status. In February 1760, he was arrested in Warsaw and sent to a Church tribunal. He was convicted of heresy and imprisoned in the Jasna Góra Monastery in Częstochowa for thirteen years.
The legacy of Frankism continued through his daughter, Eve, and into the wider population. After Jacob Frank died in 1790, Eve became the leader of the sect.
