Anjezë Gonxhe Bojaxhiu, better known as Mother Teresa, was an Albanian-Indian Roman Catholic nun who devoted her life to serving the sick, poor, and dying.

After nearly two decades of teaching in Calcutta, India, she experienced a profound "call within a call" in 1946 to leave the comfort of the convent and work directly among the city's destitute in the slums. In 1950, she established the Missionaries of Charity, a religious congregation that rapidly expanded globally, with members taking an additional vow to offer "wholehearted free service to the poorest of the poor."

Her order founded homes and hospices worldwide, including Nirmal Hriday (Home for the Pure of Heart) for the terminally ill, offering care, dignity, and compassion to the abandoned. Her lifetime of humanitarian dedication was recognized with the Nobel Peace Prize in 1979, and she was later canonized as Saint Teresa of Calcutta by the Catholic Church in 2016.
