Boyarynya Morozova was a prominent figure in 17th-century Russia, known for her strong opposition to the reforms of Patriarch Nikon. Born into a noble family, she became a symbol of resistance against the changes that aimed to align the Russian Orthodox Church with Western practices. Morozova was arrested in 1658 for her beliefs and was later exiled. Her steadfastness and commitment to her faith made her a martyr for the Old Believers, a group that rejected Nikon's reforms. Today, she is remembered as a significant historical figure in Russian religious history.
