The Bishop Hill colony underwent a major upheaval in 1850 after the murder of Erik Jansson. Jansson was assassinated by a former colony member, John Root, who was upset with Jansson for interfering with his marriage to one of Jansson's cousins. After their leader's death, the people of Bishop Hill appointed a group of seven trustees to run the affairs of the colony. Among the trustees were Jonas Olsson and Olof Johnson, who would become the primary leaders of the colony as they had been two of Jansson's closest aides. Under these two men and the rest of the trustees, the colony continued to grow and flourish. The workforce was reorganized to become more efficient and more buildings were erected. However, despite Bishop Hill's success, in 1857 financial problems arose in the midst of accusations of mismanagement against Olof Johnson. Johnson had made several large investments, without colony approval, that had turned out to be disastrous. As Bishop Hill headed for financial ruin, colonists voted to end the communal system. In 1861 the formal dissolution of the colony was official, and many of its people would soon be forced to move away.
