"Maria Montessori, busy giving lectures in various cities, committed herself to raising public awareness of “modern charity,” where the theme of the “new woman” emerged. She became a champion of women's emancipation and ideals of peace. In March 1896, she became co-founder and deputy secretary of a Roman women's association and in 1899 she joined the Maternal Union. She took up the women's cause in international forums, such as the Women's Congress in London in 1899, where she was approached by Guido Baccelli (1830-1916), who had experienced the barricades that defended the Roman Republic from the assault of French troops in 1849 and was seven times Minister of Education. Also in 1899, Montessori joined the Theosophical Society, founded in 1875 in New York for the study and dissemination of theosophy (divine wisdom) and esoteric sciences. Adhering to the Masonic principle of “universal brotherhood,” theosophy was based on the motto “there is no religion higher than truth.” No specific profession of faith was required of its members. This institution and its official organ, The Theosophist (1879), were founded by Helena Blavatsky (1831-1891), a Russian-born American philosopher, theosophist, occult essayist, and medium, and Colonel Henry Steel Olcott (1832-1907) ."
