The Great Balkan War (Acts of Union)

The Great Balkan War as it is coloquially known was the post World War I aftermath of the Balkan/Eastern Front which saw Bulgaria for the most part take part in the unrestricted killing of nearly 3.5 million people of its newly conquered territories as well as the displacing of roughly 1.5 million more. It is widely considered a Genocide by modern standards and remains widely criticised as one of the worst genocides of the many which occured in the 20th century due to its extremely brutal massacre tactics, forced marches, displacement in favor of Bulgarian settlers, and a fabricated famine.

The starting time period is February of 1919, The Bulgarian  authorities rounded up, arrested, and deported thousands of Greeks, Serbians, Hungarians, and Romanians, the majority of whom were eventually murdered. The genocide was carried out  after World War I and implemented in two phases: the wholesale killing of the able-bodied male population through massacre and subjection to army conscripts into forced labour, followed by the deportation of women, children, the elderly and infirm on death marches leading to the the border with Ukraine where usually they would settle into the local populations or die due to the ongoing Russian Civil war.
