Fomenko New Chronology. Some of its claims are:
Histories of Ancient Rome, Greece and Egypt were crafted during the Renaissance by humanists and clergy mostly on the basis of documents of their own making.
There was no such thing as the Tartar and Mongol invasion followed by over two centuries of yoke and slavery, because the so-called "Tartars and Mongols" were the actual ancestors of the modern Russians, living in a bilingual state with Turkic spoken as freely as Russian. So, Russia and Turkey were once parts of the same empire. This ancient Russian state was governed by a double structure of civil and military authorities and the hordes were actually professional armies with a tradition of lifelong conscription (the recruitment being the so-called "blood tax"). The Mongol "invasions" were punitive operations against the regions of the empire that attempted tax evasion. Tamerlane was probably a Russian warlord.
Official Russian history is a blatant forgery concocted by a host of German scholars brought to Russia to legitimize the usurping Romanov dynasty.
