Tsarevna (Russian: царевна, pronounced as /ru/) was a title given to the daughters of tsars in Russia before the 18th century.[1] The male equivalent was tsarevich.
All of them died unmarried with the exception of the daughters of Ivan V. Notably, his daughter Catherine married Karl Leopold of Mecklenburg-Schwerin.
Both tsarevna and tsarevich were replaced with grand duchess and grand duke (with tsesarevich given to the heir apparent).
