The World Bank was formed in 1944 at the Bretton Woods Conference to provide financing for post-war reconstruction efforts and development projects in member countries. It aims to reduce poverty and support development by providing long-term loans, technical assistance, and policy advice to governments. The World Bank Group consists of five institutions focused on global development, including the International Bank for Reconstruction and Development and International Development Association, which provide loans and grants to middle-income and poorer countries respectively.
