What were the popular religions in the 1800's?
It was mostly christian, although in In England there were more active members in non-Anglican churches than the church of England.
there are 6 major religions in the world right now known all over the place (eg. Christianity, judaism, Islam, Hinduism, Sikhism and Buddhism) these religions have been known for centuries and alot MORE than that. These religions would've been popular still in the 1950s Now we have areoplanes and transport to go to any country with our religions And it really depends on what continent/country you are talking about.
