The year 1900 is when the first major jewish emigrations happened to America. Throughout the early 1900's the jews suffered a series of pogroms that resulted in increasingly massive waves of jewish emigration into New York City. WW1 also caused a huge emigration.
By 1924, New York City was around 40% jewish, and most other major cities were at least 20% jewish. At this point Congress had enough and shut down immigration from Southern and Eastern Europe with the 1924 immigration act. Some jews would hop to Britain, and then to the US, but to a large degree the immigration was stopped.
As a side note, jews blame that 1924 act for trapping them in europe and leading to the holocaust, which is why they're so pro-immigration, but that's another story.
So that's the history.
America has always had new religious movements popping up all over the place. There's so many newfangled bibles, and new ideas, and new doctrines, they're popping up all the time like popcorn. Mormonism is just one of the thousands of such movements that have sprung up.
Cyrus Scofeld was a guy from Kansas who created his own newfangled interpretations pertaining to jewish nationalism. His interpretation said that "Israel" is a physical piece of land, it belongs to the jews, and it's your christian duty to fight for it. He also created the idea of "dispensationalism", which is basically "the hand of fate must be forced". In other words, it's our duty to force the biblical prophecies to happen. If we want the End Times and the Rapture, then we have to build the Third Temple.
His bible was a reference guide with notes in the margins explaining how to interpret the verses. It was picked up and promoted by some influential people in New York City and was used to train the new generation of seminaries, who then were dispersed all over America to preach this new doctrine. This is what infused all of the Evangelical movements, fueled by TV revival preachers promoting this to a mass audience.
