Mother Mary Teresa Bojaxhiu, honoured in the Catholic Church as Saint Teresa of Calcutta,[7] was an Albanian-Indian[4] Roman Catholic nun and missionary.[8] She was born in Skopje (now the capital of North Macedonia), then part of the Kosovo Vilayet of the Ottoman Empire. After living in Skopje for eighteen years, she moved to Ireland and then to India, where she lived for most of her life.

In 1950, Teresa founded the Missionaries of Charity, a Roman Catholic religious congregation that had over 4,500 nuns and was active in 133 countries in 2012. The congregation manages homes for people who are dying of HIV/AIDS, leprosy and tuberculosis. It also runs soup kitchens, dispensaries, mobile clinics, children’s and family counselling programmes, as well as orphanages and schools. Members take vows of chastity, poverty, and obedience, and also profess a fourth vow – to give “wholehearted free service to the poorest of the poor.”[9]

Teresa received a number of honors, including the 1962 Ramon Magsaysay Peace Prize and the 1979 Nobel Peace Prize. She was canonised on 4 September 2016, and the anniversary of her death (5 September) is her feast day. A controversial figure during her life and after her death, Teresa was admired by many for her charitable work. She was praised and criticized on various counts, such as for her views on abortion and contraception, and was criticized for poor conditions in her houses for the dying. Mother Teresa was born Agnes Gonxha Bojaxhiu in Skopje*, Macedonia, on August 26**, 1910. Her family was of Albanian descent. At the age of twelve, she felt strongly the call of God. She knew she had to be a missionary to spread the love of Christ. At the age of eighteen she left her parental home in Skopje and joined the Sisters of Loreto, an Irish community of nuns with missions in India. After a few months’ training in Dublin she was sent to India, where on May 24, 1931, she took her initial vows as a nun. From 1931 to 1948 Mother Teresa taught at St. Mary’s High School in Calcutta, but the suffering and poverty she glimpsed outside the convent walls made such a deep impression on her that in 1948 she received permission from .her superiors to leave the convent school and devote herself to working among the poorest of the poor in the slums of Calcutta. On October 7, 1950, Mother Teresa received permission from the Holy See to start her own order, “The Missionaries of Charity”, whose primary task was to love and care for those persons nobody was prepared to look after.
The Society of Missionaries has spread all over the world, including the former Soviet Union and Eastern European countries. They provide effective help to the poorest of the poor in a number of countries in Asia, Africa, and Latin America, and they undertake relief work in the wake of natural catastrophes such as floods, epidemics, and famine, and for refugees. The order also has houses in North America, Europe and Australia, where they take care of the shut-ins, alcoholics, homeless, and AIDS sufferers. The Missionaries of Charity throughout the world are aided and assisted by Co-Workers . By the 1990s there were over one million Co-Workers in more than 40 countries. Along with the Co-Workers, the lay Missionaries of Charity try to follow Mother Teresa’s spirit and charism in their families.
