His leadership style was very different from his grandfather, as people found him to be stern, impersonal, and more like a king than a religious figure. He moved the Baha'i faith away from being about a single person and focused more on a strict administrative system. He demanded that everyone follow this system exactly, stating that a person's own conscience must give way to the will of the majority in group decisions.
Shoghi Effendi was often very critical of Baha'is in the West, especially those in America, calling them soft, materialistic, and lazy. He told them they were failing at their duties and needed shock medicine to wake them up from their inactive state. His time as leader was also marked by many painful fights with his own family members. Eventually almost all of his relatives were cast out of the religion and labeled as enemies or Covenant-breakers.
His intense focus on work was so strong that his wife said it was slowly killing him. He spent nearly all his time reading and writing thousands of letters, which left him with almost no time for rest or a normal personal life. When he died suddenly in 1957, it caused a massive crisis because he did not leave a written will or name a new leader to follow him. This left the entire community in a state of great confusion and fear about how to survive without any clear instructions.
