What were three important events in the worldwide advent awakening?

The worldwide Advent Awakening, which spanned the 19th century, was marked by several significant events. Firstly, the Great Disappointment of 1844, when followers expected Jesus' return, led to a reevaluation of beliefs and the formation of new Adventist movements. Secondly, the establishment of the Seventh-day Adventist Church in 1863 formalized a distinct religious group focused on the imminent return of Christ. Finally, the publication of "The Great Controversy" by Ellen G. White in 1888 helped to spread the Adventist message and solidify theological foundations within the movement.
