She was born as Agnes Bojaxhiu in Macedonia in 1910. She worked and helped people in the poorest of places in India, and surrounding areas. Even at the young age of 12, Mother Teresa was determined to help the poor. It was at that age that she performed missionary work in India. At 18, she joined a community of nuns in Rathfarnham. In 1937 at the age of 27, she took her final vows and officially became Mother Teresa. For eighteen years, Mother Teresa taught at a school in Calcutta and was the principal for the last four. She then became an independent nun and started her own order. Mother Teresa became famous for her work over the next four decades and received the Nobel Peace Prize in 1979.
