The Mariavite Church is today one of two independent Christian churches collectively known as Mariavites who first emerged from the religious inspiration of Polish noblewoman and nun, Feliksa Kozłowska (1862-1921) in the late 19th-century. Initially, it was a renewal movement seeking reform in Polish Catholicism. The movement was an attempt to replicate the simplicity of the life of Mary, in Latin, qui Mariae vitam imitantur, ("Let them imitate the Life of Mary"), thus vita Mariae, the Life of Mary, gave the movement its name.
