The Office of Economic Opportunity (OEO) was a U.S. government agency created in 1964 as part of President Lyndon B. Johnson's Great Society initiative, aimed at combating poverty and promoting economic self-sufficiency. It played a central role in the implementation of various programs designed to assist low-income individuals and families, making it a cornerstone of the War on Poverty. The OEO established community action agencies, provided job training, and supported educational programs to uplift disadvantaged populations.
