Final answer:
It is chronologically inappropriate to refer to Russia or Ukraine in the year 1200 because they were part of Kievan Rus', which had a different political and cultural legacy prior to the Mongol invasion and the eventual rise of Moscow.
Step-by-step explanation:
It is chronologically inappropriate to talk about Russia or Ukraine in 1200 because at that time, what we now refer to as Russia and Ukraine were part of a different political and cultural entity known as Kievan Rus'. It wasn't until the mid-thirteenth century that Kievan Rus' fell to Mongol invaders, leading to political disintegration in the region. Before the rise of Moscow as a prominent power center and eventually 'Third Rome', the areas comprising modern Russia and Ukraine had entirely distinct histories.
Furthermore, the region's history during and after the 1200 involves complex relationships between the Eastern Slavic people, the influence of the Byzantine Empire, various Norse rulers, and overlapping territories with powers such as Poland and the Mongol Empire. Therefore, considering Russia or Ukraine in their present forms during the 1200s overlooks the rich and diverse historical tapestry from which these nations evolved. It also disregards the period of Mongol dominion that greatly affected the cultural and political development of the region.
