Agnes Bojaxhiu, or Mother Teresa as the world knows her today, was born on 26 August 1910, in Yugoslavia. In 1928 she left home to become a novice of Loreto and in 1931 she arrived in India, where she took religious vows of poverty, chastity, and obedience and was renamed Teresa. After teaching at St. Mary's School in Calcutta for several years, Mother started the Congregation of the Missionaries of Charity, which was approved by a decree of the Holy See in 1950. Since then, the congregation has expanded to include more than six hundred Homes in as many as a hundred and thirty-six countries.
