The Africa Genocide

It was the greatest human cruelty ever performed. In later years it became the only event that had an entire month relegated to remembrance, besides pride month.

In the final decades of the 21st century, the white man had become tired of his burden of trying to uplift societies economically over time as allies. The world had divided itself into various regional continental sized powers. Of these Africa was the only one which had developed at a rate so slow that there was thrice the gap between the rest of the world and Africa at the end of the century, than had been at the beginning of the century. This was primarily due to Africa having made the mistake of trying to set up directly towards a continental union when there weren't even the first signs of regional unification visible. This led to a state where nothing could move or be built upon as there was no real central leadership to the continent that could be followed and obeyed.

In North America the black populace had become an even smaller minority group which had been overshadowed by the Latinx and and Asian populations that moved to the region.

In South America the black population integration project never took off.

In Asia racism was and remains rampant.

In Europe there was greater controversy of Europeans actively keeping the African populations out even though they were low on labor pools due to declining populations. The multi generational black population of Europe never considered itself to have any ties to Africa.

As the African GDP continued to decline and civil wars continued to occur. It was the only remaining continent with rich mineral supplies that might change the power balance in favor of whichever continental power got to it first.

Patience for soft power had run out. In Central Asia the 'Greater China' empire was more than happy to send autonomous machine swarms that killed off populations indiscriminately. The North American federation in turn sent it's own troops to take over the region and claim power nodes in non Chinese troop territories. However the brutality of the conflict imposed by the Chinese troops led to them getting the upper hand and the North America federation grudgingly began implementing similar under the radar extermination ops to get faster control of the mineral deposits and win.

The South Americas quickly followed, meanwhile the European Union now extending all the way to Ukraine provided a security guarantee to North Africa while South Africa maintained safety in the Southern African region with the threat of nukes.

The greater India Empire in turn tried to improve trade ties in East Africa and spoke in support of those territories on the global stage.

In the end however the Continent of Africa had become plagued by multiple extermination swarms that were supposedly went out of control. All sides of the conflict threatened to nuke each other if a continental EMP was pre emptively launched. By the time the issue was taken to a vote the lands of Western, middle, and Eastern Africa were barren of all life. With publicly banned satellite images displaying sands pockmarked with with bones from one end of the continent to the other.

After the event free movement of labor was opened to the people of South and North America as a display of the world's shame, and the last human civilizations of Africa were quick to collapse due to the outflow of it's peoples, who were forever minorities in every country that they dispersed to.

The last visibly black man ceased to exist by the year 2300.
