Answer:
After World War I, Europe began the process of rebuilding through a combination of government initiatives, private enterprise, and international aid. Governments established programs to aid in the rebuilding of infrastructure, industry, and transportation networks. Private businesses and entrepreneurs began to invest in new businesses and industries, often with the help of government subsidies and incentives. International aid organizations, such as the League of Nations, the European Recovery Program (ERP), and the Marshall Plan, also provided resources and assistance to help European countries rebuild.
