The Rus’, also known as Russes, were a people in early medieval Eastern Europe [Rus’ state formed 862 CE]. The [non-Rus’] scholarly consensus holds that they were originally Norsemen, mainly originating from present-day Sweden, who settled and ruled along the river-routes between the Baltic and the Black Seas from around the 8th to 11th centuries CE…. They ultimately gave their name to Russia and Belarus, and they are relevant to the national histories of Russia, Ukraine and Belarus. Because of this importance, there is a set of alternative so-called “anti-Normanist” views that are largely confined to a minor group of Eastern European scholars…. The origin of Kievan Rus’ is infamously contentious, and relates to its perceived importance for the legitimation of nation-building, imperialism, and independence movements within the East Slavic-speaking world, and for legitimating different political relationships between eastern and western European countries.
“Normanism” is the idea that the Rus’ had their origins among the Normans (i.e. among “Northmen”). The idea that [Vikings] founded Rus was seen as politically unacceptable by many [anti-Normanist] Russian historians…. [Wikipedia]
The shorter of it is multiple indigenous groups whose ancestors took the Baltic and Black Sea areas as Indo-European conquerors (while breeding the prior hunter-gatherer expansions, the prior conquerors who 40k–50k years ago took it from Neanderthals) who had fought among themselves until the Norsemen came. The preferred narrative of current Slavic conquerors is that they descend from the Indo-European indigenous tribal identity groups who fought the Indo-European Norsemen invaders (by ignoring/obfuscating vast archaeological/archaeogenetic evidence that their recent Indo-European ancestors were an admixture of hyperviolent expansionists going back 55k years out of Africa expansion of their form throughout Eurasia, ‘displacing’ prior homininans, as EMH, Early Modern Humans).
The Kurgan hypothesis: South Russia as the urheimat of Indo-European peoples whose culture (if not ethnic/genetic form) dominates modern techno-industrial overcomplex monetary society, i.e. metastatic modernity.
Recent Russian behavior is a history of attacking others, when deemed “necessary,” as the others do, e.g. the U.S. of Americans.
Perhaps add US proxy wars to the list
