Moscow appeared as a princedom in 1277 at the decree of the Tatar-Mongol Khan Mengu-Timur and it was an ordinary ‘ulus’ (subdivision) of the Golden Horde. The first Moscow prince was Daniel (1277-1303), younger son of Alexander, so-called ‘Nevsky’. The Riurykovich dynasty of Moscow princes starts from him. In 1319 Khan Uzbek (as stated in the afore-mentioned work by Bilinsky) named his brother Kulkhan the virtual Prince of Moscow, and in 1328 the Great Prince of Moscow. Khan Uzbek (named in Russian history as Kalita), after he converted to Islam, destroyed almost all the Riurykovich princes. In 1319-1328 the Riurykovich dynasty was replaced by the Genghis dynasty in the Moscow ‘ulus’ of the Golden Horde. In 1598 this Genghis dynasty in Moscow which began with Prince Ivan Kalita (Kulkhan) was finally broken. Thus for over 270 years, Moscow was ruled solely by the Khans of Genghis.
Still, the new dynasty of the Romanovs (Kobyla) promised to follow former traditions and solemnly swore allegiance to the age-old dynasty of Genghis.
In 1613 the Moscow Orthodox Church became the stabilizing force to safeguard the sustainment of Tatar-Mongol government in Moscow, offering Masses for the Khan, and issuing anathemas on anyone who opposed this servitude.
Based on these facts, it becomes clear that Moscow is the direct inheritor of the Golden Horde Empire of Genghis and that actually the Tatar-Mongols were the ‘godfathers’ of Moscow statehood. The Moscow princedom (and tsardom from 1547) up until the XVI century had no ties or relationships with the princedoms of the lands of Kyivan Rus.
