Beginning in the 1930s, African American attorneys developed a long-range strategic plan to use the legal system to challenge official segregation in the United States. Two institutions led the way: the Howard University School of Law and the National Association for the Advancement of Colored People (NAACP). Lawyers, many trained at Howard and supported by the NAACP, helped African American plaintiffs bring lawsuits against segregated school systems. Case by case, their efforts began to undermine the legal principle of separate but equal.

Within years of its founding, the NAACP played a critical role in litigation challenging voter restrictions (Guinn v. United States, 1915), residential segregation (Buchanan v. Warley, 1917), successfully won the right for African Americans to serve as military officers during World War I, and secured federal oversight of state criminal justice systems (Moore v. Dempsey, 1923). These early victories laid important legal groundwork that would later support broader civil rights reforms.

Echoing the focus of Du Bois' Niagara Movement for civil rights, which began in 1905, NAACP aimed to secure for all people the rights guaranteed in the 13th, 14th, and 15th Amendments to the United States Constitution. A series of early court battles, including a victory against a discriminatory Oklahoma law that regulated voting by means of a grandfather clause (Guinn v. United States, 1910), helped establish the NAACP's importance as a legal advocate. In 1930 the association commissioned the Margold Report, which became the basis for the successful reversal of the separate-but-equal doctrine that had governed public facilities since Plessy v. Ferguson (1896). In 1935, White recruited Charles H. Houston as NAACP chief counsel…whose strategy on school-segregation cases paved the way for his protégé Thurgood Marshall to prevail in 1954's Brown v. Board of Education, the decision that overturned Plessy.

Starting in the 1920s, the N.A.A.C.P continuously challenged specific aspects of educational inequality in the courtroom. From graduate programs in Texas that refused to admit black applicants to school districts in California that forced Mexican-American students to attend school miles from their home, the N.A.A.C.P. legal team successfully targeted examples of educational segregation in the decades prior to the Brown decision. These lower court decisions provided a legal foundation for the comprehensive victories of the N.A.A.C.P. in the 1950s, including the landmark decision in Brown.

Founded February 12, 1909, the NAACP is the nation’s foremost, largest, and most widely recognized civil rights organization. A series of early court battles, including a victory against a discriminatory Oklahoma law that regulated voting by means of a grandfather clause (Guinn v. United States, 1910), helped establish the NAACP’s importance as a legal advocate. In 1930 the association commissioned the Margold Report, which became the basis for the successful reversal of the separate-but-equal doctrine that had governed public facilities since Plessy v. Ferguson (1896). Houston’s strategy on school-segregation cases paved the way for Thurgood Marshall to prevail in Brown v. Board of Education (1954), and the NAACP’s Washington, D.C., bureau helped advance passage of the Civil Rights Acts of 1957, 1964, 1968 and the Voting Rights Act of 1965.

In the early 1930s, the organization embarked on a long-range, carefully coordinated litigation campaign that challenged the laws that enforced segregation. During the years that followed, a legal revolution was set into motion that altered the foundations of American jurisprudence. Part III examines the significance of the Margold Report, a study that was commissioned by the NAACP's Board of Directors in the early 1930s. The report contained a detailed examination of the "separate but equal doctrine" of Plessy v. Ferguson and suggested ways in which the policy might be challenged in the courts. After Houston was selected to head the NAACP's litigation campaign in 1935, he modified the Margold Report's recommendations and developed what became the "equalization strategy"…In a series of cases in Maryland, Missouri, Texas, and Oklahoma, the NAACP's lawyers were able to chip away the foundation of segregation.

The NAACP's fight against segregated education—the first public interest litigation campaign—culminated in the 1954 Brown decision. He argues that the dedication and the political and legal skills of staff members such as Walter White, Charles Hamilton Houston, and Thurgood Marshall were responsible for the ultimate success of public interest law.

The first phase commenced in 1935 with a long-range, carefully orchestrated series of lawsuits that culminated with the 1954 decision in Brown v. Board of Education. This Essay is an overview of the legal campaign, including the organization, development, and execution of legal challenges to segregation, by the NAACP working with national and local Black lawyers’ organizations. By the early 1930s, the "separate-but-equal" doctrine was firmly entrenched…He devised an indirect approach instead: the "equalization strategy."…an adequate foundation for a direct challenge to Plessy had been established.

Professor Tushnet's narrative traces the NAACP's program to outlaw segregation in education from its origin pursuant to a 1930 grant from the American Fund for Public Service…to the institution of the school-segregation litigation in Kansas and South Carolina in 1950. Viewed in this light, the NAACP's legal strategy to outlaw segregated education followed a cohesive, unitary course from Margold to Marshall.

Founded in 1909, the National Association for the Advancement of Colored People grew quickly, setting agendas and developing tactics that propelled the civil rights movement through the 20th century. Scholars emphasize the organization's national initiatives, the political lobbying and publicity efforts handled by the headquarters staff in New York and Washington D.C. and the court strategies developed by the legal team based for many years at Howard University. When the Southern civil rights movement gained momentum in the 1940s and 1950s, credit goes both to the Legal Defense Fund attorneys and to the massive network of local branches that Ella Baker and other organizers had spread across the region; most important, it was in the local organizations that the work of building a culture of Black political activism was carried on, a key to progress in civil rights struggles throughout the last century.

During World War II the NAACP renewed efforts to end discrimination in the military. As the United States entered World War II, the NAACP joined union organizer A. Philip Randolph in support of a massive March on Washington to protest discrimination in the armed forces and defense industries. The following year, in response to NAACP pressure, President Harry Truman issued two executive orders banning discrimination in federal employment and armed forces. On the legal front, the Supreme Court handed the NAACP important victories against all-white voting primaries, segregation in interstate travel, and restrictive covenants in Smith v. Allwright, Morgan v. Virginia, and Shelley v. Kraemer.

The NAACP devoted much of its energy during the interwar years to fight the lynching of blacks throughout the United States by working for legislation, lobbying, and educating the public. It organized the appeals for twelve black men sentenced to death a month later based on the fact that testimony used in their convictions was obtained by beatings and electric shocks, and it gained a groundbreaking Supreme Court decision in Moore v. Dempsey (1923) that significantly expanded the Federal courts' oversight of the states' criminal justice systems in the years to come. The NAACP’s Legal department, headed by Charles Hamilton Houston and Thurgood Marshall, undertook a campaign spanning several decades to bring about the reversal of the "separate but equal" doctrine announced by Plessy v. Ferguson, culminating in the unanimous 1954 Supreme Court decision in Brown v. Board of Education.

The NAACP pledged "to promote equality of rights and eradicate caste or race prejudice among citizens of the United States; to advance the interest of colored citizens; to secure for them impartial suffrage; and to increase their opportunities for securing justice in the courts, education for their children, employment according to their ability, and complete equality before the law." The NAACP pursued this mission through tactics including legal action, lobbying, peaceful protest, and publicity. During the interwar years the NAACP devoted much of its energy to fighting the lynching of Blacks throughout the United States by working for legislation, lobbying, and educating the public, establishing patterns of legal and political campaigning that would later characterize mid‑20th‑century civil rights efforts.

Major campaigns for equal access to education, voting, employment, housing and the military are covered in this module. The education files in this module document the NAACP’s systematic assault on segregated education that culminated in Brown v. Board of Education in 1954. Efforts against the "white primary" began in Texas in the 1920s…The litigation included several appeals and decisions before the U.S. Supreme Court—Nixon v. Herndon (1927) and Nixon v. Condon (1932)—and the ultimate vindication of the NAACP's efforts by the landmark ruling in Smith v. Allwright in 1944, which unequivocally declared "white primaries" unconstitutional.

The collection documents the strategic importance of efforts to eradicate barriers to racial equality in American education, voting, employment, housing, the military, and criminal justice system. Beginning with the development of an ambitious legal strategy by Nathan Margold, the NAACP began mapping out an ambitious legal program to seek equal justice, full citizenship rights, and an end to racial discrimination in the United States.

The legal arm of the NAACP led the campaign to end segregation altogether, but it first targeted inequality in education. It helped win the admission of a Black student to the University of Maryland Law School because that state did not have such an institution for Black students. In October 1938 the NAACP filed suit over the fact that Black teachers in Norfolk were paid less than their white counterparts. In Alston v. School Board of the City of Norfolk, a federal court ruled that this discrimination was based on race alone and thus violated the "equal protection" clause of the Fourteenth Amendment to the U.S. Constitution.

Assessments of the Civil Rights Movement have credited various organizations, but it was the NAACP, serving as a powerful legal instrument and political machine, that achieved the basic constitutional reforms that were required to end Jim Crow. Through sustained litigation and political lobbying over several decades, the NAACP helped to secure landmark Supreme Court decisions and federal civil rights legislation.

The NAACP's public campaigns against lynching in the 1920s drew increasing attention to the importance of fund raising and lobbying within the organization. These campaigns helped establish the NAACP as a leading national voice against racial violence and laid groundwork for later legal and legislative initiatives through its Legal Defense and Educational Fund, founded in 1940.

Historical context material on the NAACP notes that the organization fought for both equal funding and desegregation of African American schools in the 1930s, such as in South Carolina in 1938. Years later, the NAACP legal team found success through Brown v. Board of Education (1954), in which the Supreme Court ruled unanimously that racial segregation in schools was unconstitutional. This framing presents the pre–World War II school cases as precursors to the landmark 1954 decision.

The NAACP’s long battle against de jure segregation culminated in the Supreme Court’s landmark Brown v. Board of Education decision, which overturned the “separate but equal” doctrine. The exhibit describes how the NAACP’s decades-long legal campaign and earlier battles against segregation and discrimination in education built toward this 1954 victory and subsequent civil rights legislation in the 1950s and 1960s.

They found that by 1930, World War I veterans comprised 15 percent of male members of the NAACP, the leading civil rights organization of the period. The significant discrimination Black troops faced while serving in the Great War seeded deep feelings of institutional betrayal and discontent that compelled many veterans to challenge the status quo after 1918, often by joining the NAACP and playing key leadership roles in the early Civil Rights Movement.

Founded as an interracial organization in 1909, the NAACP’s early decades saw an agenda centered on anti‑lynching activism, campaigning for federal anti‑lynching legislation and educating the public about mob violence. During the civil rights era of the 1950s and 1960s, the NAACP’s earlier legal and political work evolved into direct involvement in major civil rights victories, including school desegregation and voting rights campaigns. The continuity between its early anti‑lynching and legal campaigns and later civil rights victories illustrates how the NAACP’s post‑World War I activities helped create the institutional and strategic foundation for mid‑century civil rights successes.

Black veterans who were in the forefront of the leadership of the Civil Rights Movement; their strong resolve to address the paradox of military service abroad and the denial of basic rights at home brought deeper meaning to the word ‘Democracy,’ and through their example motivated others to join and actively participate in the NAACP and other civil rights organizations, and ultimately transform the face of America. The NAACP educates all of its members, their families, and our communities about the difficult challenges Black veterans faced when returning home and their crucial role in advancing civil rights.

The NAACP continues to be the strongest national multiracial voice for political, educational, social, and economic equality. Histories of the organization from the King Institute describe its early twentieth‑century efforts against lynching, segregation, and disenfranchisement as the beginning of a sustained struggle that later led to major civil rights victories in courts and Congress during the mid‑twentieth century.

The NAACP was founded in 1909 in response to ongoing violence against Black people in the United States. In the decades after World War I, it pursued a combination of legal challenges, lobbying, and public campaigns against lynching and segregation, which historians widely describe as laying crucial groundwork for the civil rights victories of the 1940s–1960s, including Supreme Court decisions and federal civil rights legislation.

Historically, the NAACP has played a vital role in outlawing lynching, advocating for voting rights, and the civil rights movement. Their organizing efforts during the Civil Rights Movement and continued influence on civic engagement today highlight decades of advocacy that contributed to major civil rights victories.

As chief of the NAACP Legal Defense and Educational Fund, Thurgood Marshall led the legal fight against segregation and argued the historic 1954 case Brown v. Board of Education. NAACP materials portray Marshall’s work as part of a long legal strategy developed within the organization, building on earlier decades of litigation and advocacy to achieve this major civil rights victory.
