Within these societies, there are different groups of people that have different philosophies and beliefs. Interestingly enough, there’s a group for everybody, including those who adhere their lifestyle to what they believe is divine and all-powerful. 

 Religions have been around for thousands of years, and they come in all forms. From societies that believed there were multiple gods and goddesses with different powers to monotheistic ones where people believe there’s only one God that reigns the world. 

 All around the world and across many cultures, there are many religions but we can divide the world’s main religions into two categories: Indian religions, which are Hinduism and Buddhism; and the Abrahamic religions, which are Christianity, Islam, and Judaism. 

 Let’s take a look at which of these are the largest and most practiced religions of them all, and what makes them so popular.

Cao Dai is a Vietnamese philosophy that has approximately five million followers. It started out in Vietnam during the 1920s, spread by Ngo Van Chieu, who proclaimed that he had received a message from a god called the Supreme Being during a supernatural reading session. 

This religion is one of the more recent ones around, and it gathers many elements and customs from other organized religions. Some customs are the same as Daoism, Judaism, and Christianity, with its main teaching being to spread tolerance, love, and peace. 



Shintō is a polytheistic belief. This means that it fosters the idea that there’s more than one God. Shintō originated in Japan during the 8th Century A.D. It isn’t an organized religion per se, but it functions as the foundation for many customs in Japan. 

Shinto has around one hundred million followers, and this religion revolves around what they call “kami,” which are the supernatural entities they believe inhabit the Earth. The followers of Shinto honor the kami and the divine spirits with shrines. These can include personal shrines in their household or public shrines dotted around Japan.  

Wrapping Up 

As you have seen in this article, there are many religions around the world. Some may follow similar concepts and belief systems, while others are totally different from others. Whatever the case may be, these religions have millions of followers concentrated around their respective territories while also consisting of smaller communities around the world. The religions with the most followers are monotheistic, with Christianity, Islam, and Judaism leading the way. Buddhism and Hinduism, which don’t have a monotheistic structure, also make the top 5 largest religions.  

Of course, you can’t forget that this list is just a compilation of the largest religions and philosophies. There are countless other beliefs that don’t necessarily align with the ones we talked about here.
