Maria Bohuslavka or Maria Boguslavka was a legendary heroine who lived in Ukraine in the 16th or 17th century. She is primarily known from many Ukrainian epic ballads (dumas), usually referred to as Duma about Marusya Boguslavka, and other Ukrainian folklore. Her nickname 'Boguslavka' refers to her origin, the city of Boguslav. 
Marusya was kidnapped and sold into a Turkish harem. The duma tells how she earned the trust of her husband and gained access to the keys of the palace, including the prison. She used them to free a group of Ukrainian Cossacks who had been imprisoned for 30 years. However, she did not flee with them but remained in the harem since this was now the only life she knew.
