Екатерина I
In 1698, Catherine was interrogated for potential involvement in the Streltsy Uprising on the tsar Peter the Great, but released after it had been established that she had nothing to do with it. According to contemporaries, she was the only one of the half-sisters of tsar Peter the Great never to have angered him, because she never involved herself in politics. She participated in the Orthodox baptism of Catherine I of Russia.
