St. Teresa of Calcutta, better known as Mother Teresa, was a Catholic nun and missionary who dedicated her life to serving the poorest of the poor. Born in 1910 in Skopje, she joined the Sisters of Loreto as a young woman and later felt a call from God to leave the convent and work among the destitute in the slums of Calcutta, India. In 1950, she founded the Missionaries of Charity, a religious order devoted to caring for the sick, hungry, and dying. Through her simple acts of love, tireless service, and deep compassion, Mother Teresa became a global symbol of charity and humility. She received the Nobel Peace Prize in 1979 and continued her mission until her death in 1997. Canonized as a saint in 2016, she is remembered as a model of selfless love and unwavering faith.
