Tatyana was born the daughter of Tsar
Michael of Russia and
Eudoxia Streshneva, and the sister of Tsar
Aleksei I of Russia. In contemporary Muscovite custom, Russian princesses were completely secluded from the world outside of the women's quarters of the
terem, not allowed contact with men nor allowed to marry. As they were not permitted to marry a non-Orthodox nor a partner below their social status, and there were no Orthodox Kingdoms other than Russia at the time, daughters of the tsar were expected never to marry, nor have any contact with men outside of the family during their life. Tsarevnas attended church and even official state processions covered by screens, and made their pilgrimages to convents in covered sleighs and wagons, as was in fact the custom for all Russian noblewomen at the time. Tatyana followed these rules, but she was also able to exert some degree of influence at court. She was known as a supporter of the reforms of
Patriarch Nikon of Moscow. She had a good relationship with her brother tsar Alexei. ==Sophia's regency==
