The Great World War (Terra Cognita)

The Great World War, also known as the The Great Calamity, and often abbreviated GWW, was a global war that lasted from. The vast majority of the world's countries—including all the great powers—eventually formed three opposing military alliances. A state of total war emerged, directly involving more than 100 million people. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. The Great World War was the deadliest conflict in human history, marked by 70 to 85 million fatalities, most of whom were civilians. It included massacres, genocides, strategic bombing, premeditated death from starvation and disease, and the only use of thermobaric weapons in war to date.

Many of the territorial gains of Tataria during the Great Eurasian War were lost due to the Tatar Civil War that followed. The simultaneous Wendish Civil War witnessed the disintegration of that monarchy with the deposition and murder of King Stanislaw III and the royal family. The Wendish war led to the rise of Centonerism which spread into the neighboring Tatar Civil War, allowing two Centonerist powers to emerge, closely linked for initial survival.

Wojtas Szélakna would obtain dictatorial power in Wendia and ushered in the next Great War upon his opening of the conflict in Yedisan. The Roman declaration of war for the Wendish invasion initiated the Great World War.
