Were they total Genocide in history just asking, people that don't exist no more

[Carlo Gesualdo]

Okay first of all this subject not pink candy coated , I stare at the abyss of time, what happen to christian kindom of Nubia there are no christian in Darfour North or South, Nubia is a lost kingdom of black christian nation that use to exist were they genocide, are brutally converted  by other religion?

What happen to nationn like Alania, les Alains de France and ect, were there people all exterminated in history, they would be unlucky enough and entirely whipeout.

This Genocide post is not about Jewish holocaust, there were survivor, , it was horrible, for them , for gentile but some did survive, are there ancient nationality that were so brutally attack they dont exist anymore or there one or 10 remaining in europe per.se, odd ancestry, what about it folks, Imagine you were the last one of a nationality ethno linguistic group, the last remaining?

I know this is grim but what if there were nation more slaughter than Jewish or Armenian, Ukrainian and so on. I mean people that were all exterminate in ancient lore ?

p.s I'm just curious if this occurs in thee past. Like an ancient Romanian people all terminated  since 400 yrs, whatever , the more you know?

I just wonder?
This is a sensitive subject I'm walking on eggs wright now, someone might ask why do you want to know this or that, I just don't know morbid curiousity or something nothing more , I swear?

When an ancient culture or nation disappears I don't think you have to assume that literally every member of that civilization was killed. They had a choice of assimilating or being eliminated. For example, the Gnostic Christians were a significant movement in Europe before Constantine installed the Catholic Church as the basis of the new Roman Empire. There is no trace of Gnosticism today. We only know about their doctrine from the Catholic tracts that denounced it. The religion was utterly suppressed and its adherents who wanted to survive either accepted the Catholic faith or practiced covertly.
