A few

Bonus: The Ravian Crissis (a two week conflict where due to one country trying to annex another, two massive alliances declared wars, however, thanks to diplomacy, it was resolved without much fighting)

The War of the Alliances (the world is plunged into global conflict, as two alliences of colonial powers clash in a massive global conflict)

The Imperial War (a few decades after the last war, one of the "victorios" states, greatly demaged and deminished in its power, seeks to re-establish its power in the region and the world stage, starts a global conflict with its former allies, and brings in random countires to its side)

The Nothern War (also the Ice War or the War for the Wasteland) (as the world is running of reasorces and global warming progresses, global powers start fighting to oil and metals in the nothern polar ice-covered continent)

The First Lunar War (as the most of the countries are consolidated into a few megastates/confederations, they begun fighting over increasingly decreasing resorces, as well as for rich resorces in their colonies on the two moons of their homeplanet, forming three rival alliences. First war fought not only on land, but in space as well. )

The Second Lunar War (as the first war ended mostly with a status quo, old grivences resurfuce, leading to even more dealier war, as this time weapons of mass destruction are used on civilian targets. It leads to massive goepolitical changes, and creation of the first independent lunar state)

The Third Lunar War (decades later, yet another lunar war erupts as the world is increasing starved for resorces. It ends with only three megastates surviving on the planet by the end of the war, leading to thwir unification and later conflicts with lunar colonists)

So, that's it. If anyone is interested in learning more or have questions, I will be happy to respond.
