What are reasons for the development of fundamentalism in 1920?

The development of fundamentalism in the 1920s can be attributed to several factors, including a reaction against modernism and scientific advancements, such as Darwinian evolution, which challenged traditional religious beliefs. The social upheaval following World War I, along with rapid changes in society and culture, led many to seek stability and certainty in religious doctrine. Additionally, the rise of secularism and the perceived moral decline of society fueled a desire to return to a strict interpretation of religious texts. This movement was further amplified by the influence of evangelical leaders who promoted a literal understanding of The Bible.
