The World Bank is an international organization formed after World War II to provide financing, advice, and research to developing nations for economic advancement, with a focus on eradicating poverty and promoting prosperity. It consists of various arms, including the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA), that offer loans and technical assistance to member countries. Despite criticisms regarding conditionalities attached to loans, the World Bank continues to play a crucial role in fostering economic development globally.
