Her place of birth and the details of her early life have not yet been precisely determined. Most often, it is claimed that the future empress was born in
Dorpat (now Tartu, Estonia). According to another version, she was born in the territory of modern Latvia - either in
Swedish Livonia or in the
Duchy of Courland, namely in Jacobstadt (now
Jēkabpils, Latvia). Said to have been born on 15 April 1684 (
O.S. 5 April), Marta's parents died during a
plague epidemic around 1689, leaving five children. At the age of three Marta was taken by an her aunt and sent to Marienburg,
Swedish Livonia (now
Alūksne, Latvia) where she was raised by
Johann Ernst Glück, a
Lutheran pastor and
Bible translator. According to some sources, she served in the Glück household as a lowly servant, scullery maid and washerwoman. No effort was made to teach her to read and write and she remained
functionally illiterate throughout her life. She spoke four languages fluently: Russian, German, Swedish, Polish, and she also understood some French. Marta was considered a very beautiful young girl, and there are accounts that Glück's wife became fearful that she would become involved with their son or husband. After the outbreak of the
Great Northern War (1700–1721), at the age of 17, she was married off to a
Swedish dragoon, Johan Cruse or Johann Rabbe, with whom she remained for eight days in 1702, at which point the Swedish troops were withdrawn from Marienburg. When Russian forces captured the town, Pastor Glück offered to work as a translator, and
Field Marshal Boris Sheremetev agreed to his proposal and took him to Moscow. After the capture of Marienburg by the Russians, Marta was taken into service by Sheremetev. she converted to
Orthodoxy and took the new name Catherine Alexeyevna (
Yekaterina Alexeyevna). She and Darya Menshikova accompanied Tsar Peter I and Prince Menshikov on their military excursions. ==Empress consort==
