Shaw is no worshiper of great persona of history, and The Great Catherine of Russia does not escape his caricature. She is shown here as a barbaric ruler of a barbaric huge powerful nation, charmed by sophistication of a mere lowly officer of the British embassy in her empire.
Every caricature has some truth distorted, and here the fact is Russia was and is a huge nation spreading from eastern one third of Europe to the very eastern edge of Asia, and as a matter of fact Alaska belongs to US only because the 99 year old lease was lost during the revolution. The great wilderness of Siberia would be a nation large enough to be among first ten if it were independent, and neighbouring Yakutia joins it in the large wilderness of deep heart of Russia. So the populace is varied, there are well over a dozen languages and many faiths. Uniting all this is no joke, and the greater of the Russian monarchs did it by commanding loyalty from their subjects as Catherine the Great did.
And yes, they did look to west for bringing some sophistication to the vast wilderness, and the court language was French, spoken even among themselves by the upper class, often at home as well. That their heart stays Russian can be no doubt, but they were no barbarians of this caricature, post Peter the Great who built St Petersburg.
