Mother Teresa MC, known in the Catholic Church as Saint Teresa of Calcutta since her canonization, (born Anjezë Gonxhe Bojaxhiu Albanian: [aˈɲɛzə ˈɡɔndʒɛ bɔjaˈdʒiu]; 26 August 1910 – 5 September 1997) was an Albanian-Indian Roman Catholic nun and missionary. She was born in Skopje (modern Republic of Macedonia), then part of the Kosovo Vilayet in the Ottoman Empire. After having lived in Macedonia for eighteen years, she moved to Ireland and then to India, where she lived for most of her life.
Teresa founded the Missionaries of Charity, a Roman Catholic religious congregation, which in 2012 consisted of over 4,500 sisters and was active in 133 countries. They run homes for people dying of HIV/AIDS, leprosy and tuberculosis; soup kitchens; dispensaries and mobile clinics; children's and family counselling programmes; orphanages; and schools. Members must adhere to the vows of chastity, poverty, and obedience, as well as a fourth vow, to give "wholehearted free service to the poorest of the poor".
