Oh, I meant “speak” in the physical sense, as he legitimately refused to speak Russian to the degree where his courtiers noted that the few times he did, he had a foreign accent in Russian by softening several letters incorrectly. He mostly only spoke English. His family on the other hand didn’t even know Russian as you yourself said.
I think I confused him somewhat with Alexander the first, who was literally a French worshiper who refused to speak anything but French.
Also Lionheart was a moron. He spent the vast majority of his life in the Middle East getting his shit pushed in by Saladin, then spent a few years galloping around France while England was burning in the background. His brother was the icing on the cake that legitimately almost destroyed the Bri’sh royalty and led to the Magna Carta.
