Anna Ivanovna was chosen to rule because her sister was married to Karl Leopold who was a grand jerk and even though she left him the Russian nobility did not want to risk him taking over. This left Anna as Praskovia was retarded. The family of Ivan Dmitriev-Mamonov did not like Praskovia, perhaps because she was retarded, her mother approved the match. She was very well loved by her mother as she was pretty but she was know to be moody. Anna was cheerful and lived with her mother after leaving her husband. Anna was described as ugly, and stupid. Peter did not think she could rule Courtland and sent down Peter Bestuzhev to rule for her. The nobility invited her to rule because they thought they could control her and they had not seen her in 20 in years. She killed 20,000 people and all the nobles who wanted her to rule as proxy for them were imprisoned, sent to exile or killed. Her lover ruled with Ostermann except in domestic cases or if she herself was slandered. He was clever but angered the Russians by hiring Germans and using thugs to impose his will.
