So, I have a country in the making in my series that has a completely different culture than the rest of the world other than belief in a religion, Prophiatism. Since the country is said to be so different and also is the heaviest place of belief in Prophiatism, almost to the point of it being a cult, could they survive as a country if they did not have any political leaders, saying this in the sense of a titled leader such as king or president?
To apply some more context, this country is called Ebrias, and Ebrisian people automatically hang, or execute by bullet, any person in their country who they find does not believe in Prophiatism at all or speaks against it. This would mean any person who could possibly cause trouble inside the country by changing other's minds on the subject or just blatantly trying to take over would be stopped before they can make any effect.
But, on the other side, since Prophiatism is also known throughout the world and is commonly followed and that Ebrias is considered the heart of the religion because of the religions lore, what would stop other countries from invading and taking over? My answer to that isn't clear but, in my thoughts, there is a god in the Prohpiatism pantheon who is a god of war. I was thinking maybe there would be a group of people in the society that choose to heavily follow this god in the pantheon creating a sort of small army with them maybe training to fight to worship that god. This would be the same with farmers following the fertility god, etc.
But still with all this, would this country still be able to survive in the world with a structure like this?
