Executive Order 10925 was issued by President John F. Kennedy on March 6, 1961, mandating that government contractors take affirmative action to ensure equal employment opportunities for all individuals regardless of race, creed, color, or national origin. This order marked a significant step in the U.S. civil rights movement, as it formally established the principle of affirmative action in federal contracting and laid the groundwork for future policies aimed at combating discrimination in the workplace.
