So, I'm considering doing a timeline where an alternate line of the House of Romanov takes the throne, and the candidate I am considering using is Ivan V, brother of Peter the Great. Now otl, Ivan didn't really do much ruling as he suffered from mental disabilities. However, if he was born healthy and hale, and somewhat smart, what differences could this prompt? Would his step mother's family still be angling for Peter to take the throne eventually? Who could a healthier Ivan V marry?
