The Democratic National Convention has been a significant event in Black history, serving as a platform for the advancement of civil rights and representation for African Americans within the Democratic Party.

One of the most notable moments in Black history related to the Democratic National Convention occurred in 1964, when the Mississippi Freedom Democratic Party (MFDP) challenged the all-white Mississippi delegation at the convention in Atlantic City. The MFDP, led by civil rights activists such as Fannie Lou Hamer and Bob Moses, sought to be recognized as the legitimate representatives of Mississippi Democrats, arguing that the all-white delegation did not represent the state's Black population. Despite facing intense opposition, the MFDP's presence at the convention brought national attention to the issue of racial discrimination within the Democratic Party.

Another significant moment in Black history related to the Democratic National Convention took place in 1984, when Reverend Jesse Jackson became the first African American to achieve substantial success in a presidential campaign. Jackson's groundbreaking campaign for the Democratic nomination energized Black voters and activists, highlighting the importance of representation and inclusivity within the party.

In more recent history, the Democratic National Convention has continued to play a crucial role in elevating the voices and concerns of the Black community within the party. From the nomination of Barack Obama as the first African American presidential candidate of a major party in 2008 to the selection of Kamala Harris as the first Black and South Asian woman as the vice-presidential nominee in 2020, the convention has been a platform for showcasing diversity and progress in American politics.
