alternate history challenge

Your challenge is to have Atenism experience a revival at some point after its decline. It doesn't necessarily have to become the state religion again, it just has to have a significant following.

Throughout history, Jews have experienced a huge number of forced mass expulsions. They were compelled to leave cities, regions, and even entire countries. Your challenge is to prevent at least one of these expulsions from happening.

The last European monarch to die in battle is generally agreed to have been Charles XII of Sweden, better known to metalheads as Carolus Rex, who was fatally shot in 1718 during the Siege of Fredriksten (though there are theories that he was actually assassinated). Your challenge is to have a...

In 1665, a country called Jaxa was founded along the Amur river by a Polish nobleman named Nicefor Czernichowski. However, twenty years later, it was conquered by the Qing dynasty. Your challenge is to have Jaxa survive until at least 1700.

The archetype of the conqueror is one that dates back to at least Sumerian times, and probably earlier. History has shown numerous examples of successful conquerors who, for good or for ill, changed history forever: Cyrus, Alexander, Chandragupta Maurya, Julius Caesar, Khalid ibn al-Walid...

Your challenge is to have Occitania be an independent country, either by remaining unconquered by France, or by having it break away at some point.

Your challenge is to have at least one country's population be mostly followers of the Bahá'í Faith by 1950. This doesn't have to be a large majority, 51% will do. Before anyone asks, I posted this in Before 1900 because I think this would be more feasible with an earlier POD.

It's not just other species and/or subspecies of humans - such as Neanderthals, Denisovans and "Hobbits" - that have gone extinct, but ethnic groups of our species as well. Russia and Brazil have seen so many ethnic groups go extinct, they have lists on Wikipedia. Your challenge is to have at...

According to Wikipedia, the 18th century had seven conflicts that could be considered "World Wars", but the 19th century only had two (three if you count the French Revolutionary Wars, which started in the 18th Century). These two were the Napoleonic Wars and the Crimean War. Your challenge is...
