Muhammad Yunus founded the Grameen Bank in Bangladesh in 1983 to provide microloans to the poor, especially women. He pioneered the concept of microcredit by giving small, collateral-free loans to impoverished borrowers who were then able to lift themselves out of poverty. By 2007, the bank had loaned over $6 million to around 7 million people in Bangladesh, though it faced challenges from defaulters and radical groups opposed to its work. Yunus won the Nobel Peace Prize in 2006 for his efforts in reducing global poverty through microcredit.
