Mother Teresa was born on 27th August 1910. She chose the day she was baptised as her birthday because this was more important to her. Her birth name was Agnes Gonxha Bojaxhiu and she was born in Macedonia. When she was 18 she went to Ireland and became a nun. Also in Ireland she chose the name Sister Teresa. Mother Teresa is famous for her work in India with the poor. For over 45 years she looked after the poor, sick, orphaned and dying. Sadly, Teresa died in September 1997. She was made a saint in September 2016.
