questons about religion/mythology

some questions i have:
1. how long does it take for a culture to form a new mythology/religon, so if in said culture a new prophet raises which teaches them a new religion and the prophet himself, is viewed as God or rather a divine being, son of the God. not a true God, but not a normal human either. This Prophet etablishes a monarchy, and his ancestors rule the new culture. The new mythology/religion has 15 Main Gods but there are also lesser gods, which some are good and help, others are evil and a plague for mankind. there ar also supposed to be various mythological beasts. but how long does it take to form such a mythology ?

The POD i am using at the moment is estimated at 100 BC.
 
For Europe and the Middle East we can see Christianity was fully fleshed out within 200 years of the first credible mention of the religion in historical texts and had become the most important religion for the future of the Roman empire (a centralized empire in which to thrive in). Muhammad did a lot of what you suggest in a grand total of 22 years that he was a prophet, and only 10 of those years was he doing anything with a great short term geopolitical impact (making an empire from scratch). Judaism on the other hand probably took much more time (perhaps even a millennium) to reach a position of uniqueness and political power.

So really any time length is possible, although 2-5 hundred years is good if you want to avoid any people shouting ASB. Closer to 200 years I would say if it has some practical advantage (like being a unique centralized, evangelical, political religion) or 500 years if it isn't that unique or is close to other pagan religions.

Other regions of the world other than Europe and the Middle East are a different story, India probably would never be able to uproot Hinduism (consider Jainism and Buddhism are minorities despite empires with great amounts of respect for both (like the Maurya Empire)), and China I am uncertain what you can expect, anywhere else in the old world is probably going to be even more uncertain, and I can't tell you anything on the New World.
 
This is essentially random. The amount of time for this to occur depends on LOTS of factors. First of all, the conduciveness to a society to new religious ideas. Secondly, how capable the 'prophet' is, and how much charisma they have. Thirdly, whether or not established authorities that oppose this prophet have enough power to stop them. Fourthly, how inclusive this religion is, especially compared to the inclusiveness of the rest of society. There's plenty of other factors, but that's just some of them.

This is a much better explanation than mine, Islam-style branches of Christianity would never had taken off in Italy in the same time period, the setting is a big influence on the success of a religion.
 
As has been mentioned in the previous posts, it depends. Jesus was teaching for roughly three years before his death and gained a decent following. Then within 15-20 years of his death his followers were recognised as a cult/offshoot of Judaism within the Roman Empire. Christianity was then adopted into the state religion some 300 years after Jesus' death. So depending how centralised and accepted you want the religion to be (local prophet, empire wide but minority religion, state religion) anywhere from a few years to few centuries will be standard.

You may also want to look at the worship of the Roman Emperors. The deification and worship of emperors (or their genius) was moderately fast-spreading but not necessarily dominant (it became another part of the inclusive Roman religion rather than supplanting it).

The cult of Asklepios in the ancient world spread relatively fast in the fifth century BC. Asklepios was a minor local deity at Epidauros before the plague hit Athens in 430 BC but spread to become the ancient Mediterraenean's major healing god in about 40-50 years after the 420s. His cult at Epidauros then remained a major healing site for a millenium after his rise in status.

Also, repeat of what has been said about Mohammed and his quick rise to prominance.

If you want more modern examples perhaps look at some cults/sects/offshoot religions that have gained publicity/notoriety in recent years and who have a leader/prophet who was instrumental in the groups rise (Scientology, Mormons, Destiny Church, Church of the Flying Spaghetti monster, various cults that committed suicide). Most of these groups never grew large enough to even come close to becoming a state religion but they'll give you an idea for how quickly a charismatic leader can gain a following of some size and attract widespread attention to their cause/religion.

For a fully formed pantheon and cryptozoology, that sort of thing generally takes time and builds on older, pre-existing myths and legends. In ancient Greece the pantheon of the 12 gods (and all the attendant lower gods and demi-gods, heroes and monsters) didn't spring fully formed into Greek culture but grew organically drawing from natural phenomena and existing myths over centuries and constantly evolving (particularly in a society with a primarily oral tradition). Roman religion grew similarly in an ever expanding way, with the Romans adopting the gods of each new people they encountered and folding them into the pantheon (and occasionally deifying people).

Hope this gives you some ideas and avenues to explore.
 
ok thanks for your answers.
also would it be possible for the culture (who are a unification between Dacians, Balts, Slavs and Scythians) to etablish a new civilization, because rome will fall appart earlier in here. The core of their new empire is in modern Styria. Afterwards the ruler of the Dynasty deports many italian citizens over, to weaken Italy itself, and to get a higher population, thus a bigger, capable army.

but would it be doable to deport italians to the empire, and how much would they deport. I think they would scatter them around, so that they cant form a strong unity anymore.

Perhaps you might consider a unified Carpathian basin, but already I'm skeptical, if there is anything we can learn from history, big disorganized tribal confederations don't tend to have staying power and get taken over by empires.
 
A Religion is not something that can be planned, designed and developed by one person or a group of individuals. The major religions founded by great persons or prophets like Christianity, Islam or Buddhism were not developed as per a plan or design. I do not think that Jesus, Muhammad or Buddha started propagating their views or giving their messages with the intention of starting a new religion or even a new sect. Their followers took those messages to heart and spread them far and wide. In course of time, developing through centuries of the efforts of millions of people they reached the present stage.
I would like to invite your attention to the fate of two "new" religions founded by two great rulers. One is "Atenism" founded by Pharaoh Akhnaton and the other "Din Ilahi" founded by the Mughal Emperor Akbar the Great. Akhnaton had based his new religion on uncompromising monotheism and his ideas were far ahead of his times. Akbar had combined the noble ideas of Hinduism and Islam together to form his "Din Ilahi". Both emperors were great rulers of their times, but both of them failed in the roles of founders of new religions. Their religions did not survive the reigns of their founders.
The last century had witnessed many "prophets" who established their own cults. Many of them also attracted large number of followers. Almost all of them proved to be counterfeit coins to dupe the gullible. The true religions are not invented or designed in laboratories or workshops, but are spontaneously developed as per the demands of a society from the teachings of the great men and spread by their faithful followers.

Tell that to L. Ron Hubbard;)

I agree with this, good points.
