With the assassination of Tsar Alexander II in 1881, the governorship ended in the Caucasus. During the reign of the new Tsar
Alexander III of Russia, Grand Duke Michael Nikolayevich served as chairman of the Imperial Council and the family moved back permanently to Saint Petersburg. Alexander III, who did not like Olga, sometimes referred to her behind her back as "Auntie Haber", hinting at her alleged Jewish heritage and illegitimacy. Such rumors of Jewish paternity followed Olga through her life. Her husband was protective of her. The Romanovs were anti-Semitic and Olga, who was not a popular member of the family, was mocked as "Frau Haber." She demanded complete obedience from her children. She was particularly close to her eldest son
Grand Duke Nicholas Mikhailovich of Russia, whose intellectual interests were like hers, but she remained aloof and cold towards the others. Her second son, Grand Duke Michael Mikhailovich, who was not intellectually gifted (she called him a fool), was a constant source of disappointment for her. In 1879, Olga with
Grand Duchess Maria Pavlovna arranged the marriage between her only daughter,
Grand Duchess Anastasia Mikhailovna of Russia, with
Frederick Francis III, Grand Duke of Mecklenburg-Schwerin, Maria Pavlovna's brother. Anastasia carried some bitterness about her upbringing and relationship with her mother - her daughter Cäcilie recounts that at a party to celebrate her engagement, when she committed some infraction she was sent to bed by Olga like a naughty child. There was also an incident involving an apricot tree, which belonged to Anastasia but whose fruit she was not allowed to eat. In his journals, Alexander Polovtsov, State Secretary during Alexander III's reign, left an unsympathetic portrayal of Grand Duchess Olga. Although he admitted she was clever, he described her as an acid-tongued, quarrelsome, idle woman, who did nothing but sit in her palace on the bank of the Neva river and gaze through the window onto the walking people and speak nasty things about them. Just a sharp-tongued high-society lady without any other hobbies but gossiping and caring about privileges for her children. ==Death==
