Mother Teresa was a Roman Catholic nun renowned for her humanitarian work. She founded the Missionaries of Charity in 1950, a religious congregation dedicated to helping the poorest and most destitute. She was born Agnes Gonxha Bojaxhiu on August 26, 1910, in Skopje, Macedonia. After joining the Sisters of Loreto in Ireland at age 18, she moved to India, where she took her religious vows and began teaching. Witnessing the extreme poverty in Calcutta, she felt a calling to serve the needy, leading her to establish the Missionaries of Charity. Her work included opening hospices, orphanages, and leper houses. Mother Teresa received numerous accolades for her efforts, including the Nobel Peace Prize in 1979. She was canonized as Saint Teresa of Calcutta in 2016. She passed away on September 5, 1997, in Calcutta, India.
