AHC: Satanism as a state religion

The challenge is to make Satanism the state religion in at least 2 nations. Bonus if one becomes a great power.

I think you need to elabirate on what you mean by "Satanism" because the word Satanism, is very broad with a very wide range of followers, each with a different veiw on "satan", just like Christianity.

So which form of Satanism would you be happy with becoming a state religion.
 
The traditional one.

are you aware that most people accused of Satanism were no Satanists?
"He obeys Satan!/She prays to the devil!" etc. were mostly false accusitions against ones enemy (see the Templars) ... a bit like "She is a witch! Burn her!".

Religions like Manaechism had a very dualistic system, with two gods. You could build upon that.
 
Satan tempts Christ doring his fast. There are, however, two interpretations as to what actually happened. One is where Christ rejects Satan's offers and Satan departs. This one was canonised later in what became Christianity. According to another Christ accepts Satan's offer, which wasn't a temptation at all but rather presenting the opposing view. Obviously in this presentation Satan presents himself as wronged party, being cast out of Heaven for simple reason of trying to free people and disagreeing with God's opinion that people need to be guided as small children. Satan also points out that Christ was sent to Earth to attone for sins of humanity when God could simply forgive them, without the need to both create and then sacrifice His Son. Christ sees his point, rejects His Father and accepts his offer of food. Which is not food at all but rather knowledge. Christ however understands that he needs to die to give people example that while knowledge can be had it's never free. Rather than wait passively for Romans to arrest him he comes to Jerusalem, announces what happened.

Despite this event turn out similary, with Christ dying on the cross.

This alternate interpretation is branded Satanism by mainstream Christianity later as they accusse its practitioners of substituting God with Satan. However it sopeads in the East, thriving in Persia and China.

One of states that emerge later adopts it as religion
 
What do you mean traditional? It was founded in 1966! It's younger than my grandparents! It barely qualifies as a religion! By all reasonable logic, this would be in Post-1900!
With a bit of goodwill, one could possibly argue that the philosophical spark that eventually led to Satanism as a spiritual movement began with John Milton's Paradise Lost. And to have Satanism achieving the status that the OP requires, one would almost certainly have to go that far back in time anyway.
 
-1°) Have Marcionism http://en.wikipedia.org/wiki/Marcionism become mainstream Christianism: since Marcion saw the God of Israel as a false god, not far from Ahriman, tenants of 'original' Christianism still worshipping the God of Abraham couls pass as 'Satanists'.

-2°) A sect follows an alternate reading of Genesis: Man differs from animals by intelligence and soul, thus correlated, intelligence is the manifestation of the soul. But Humankind was created unintelligent, 'thinking' like animals, unaware of their nudity &c...: merely fur-less pets. Humankind received intelligence, and thus a soul, from a Promethean character, Lucifer the Light-Bringer. Now this sect thrives initially in countries where Christianity and Islam are not unknown but minoritary (Indochina?), escaping persecutions. As for being the religion of a major power, it's harder: China? Japan?
 
A Yazidi-Kurdish state is established during the collapse of the Ottoman Empire or at some later period of crisis. The state religion is (unsurprisingly) Yazidism - ie. worship of the Peacock Angel, who is considered to be Satan by local Muslims and Christians.

I think the point is that the adherents of the faith -and not outsiders- have to consider Satan to be the deity that is worshipped.
 
In 1692, 17 year old, Mary Wolcott, declares during the Salem Witch Trial that she is a witch and that she will curse the American continent to years of war, death and bloodshed. Until the day the land.

In 1789 George Washington fights to have the USA become anti christian with "in the devil we trust"
