Question: Question: "What part of the constitution are affirmative action programs based in?"  Context: "Ideas for affirmative action came as early as the Reconstruction Era (1865-1877) in which a former slave population lacked the skills and resources for sustainable living. In 1865, General William Tecumseh Sherman proposed to divide the land and goods from Georgia and grant it to families of color which became the "Forty acres and a mule" policy. The proposal was never widely adopted due to strong political opposition. Nearly a century later (1950s-1960s), policies to assist classes of individuals reemerged during the Civil Rights Movement. The civil rights guarantees came through the interpretation of the Equal Protection Clause of the 14th Amendment. The decisions came to be known as affirmative action in which mandatory, as well as voluntary programs, affirmed the civil rights of people of color. Furthermore, these affirmative action programs protected people of color from the present effects stemming from past discrimination. In 1961, President John F. Kennedy became the first to utilize the term "affirmative action" in Executive Order 10925 to ensure that government contractors "take affirmative action to ensure that applicants are employed, and employees are treated during employment, without regard to their race, creed, color, or national origin." This executive order realized the government's intent to create equal opportunities for all qualified people. This executive order was eventually amended and superseded by Lyndon B. Johnson's Executive Order 11246 which prevented discrimination based on race, color, religion, and national origin by organizations which received federal contracts and subcontracts. In 1967, the order was amended to include sex as well. The Reagan administration was opposed to the affirmative action requirements of Executive Order 11246, but these contemplated changes[which?] faced bi-partisan opposition in Congress."  Answer:
Answer:
Equal Protection Clause of the 14th Amendment
