Question: In which year did this American voting rights activist, a leader in the Civil Rights Movement, and philanthropist, who wrote an autobiographical essay on the aftermath of the lynching of Joe Pullen, represent her party at Democratic National Convention?

full_context: Document 1: Mississippi Freedom Democratic Party: The Mississippi Freedom Democratic Party (MFDP) was an American political party created in 1964 as a branch of the populist Freedom Democratic organization in the state of Mississippi during the Civil Rights Movement. It was organized by African Americans and whites from Mississippi to challenge the legitimacy of the regular Mississippi Democratic Party, which allowed participation only by whites, when African Americans made up 40% of the state population.
Document 2: Emmett Till: Emmett Louis Till (July 25, 1941 – August 28, 1955) was a 14-year-old African-American who was lynched in Mississippi in 1955, after a white woman said she was offended by him in her family's grocery store. The brutality of his murder and the fact that his killers were acquitted drew attention to the long history of violent persecution of African Americans in the United States. Till posthumously became an icon of the Civil Rights Movement.
Document 3: Annie Bell Robinson Devine: Annie Bell Robinson Devine (1912–2000) was an activist in the Civil Rights Movement. From Canton, Mississippi, Devine began meeting with other blacks in Canton to discuss civil rights issues. She eventually quit her job selling insurance to work full-time for the Congress of Racial Equality (CORE). In 1964, Devine joined Fannie Lou Hamer and Victoria Gray Adams to become the first black women to speak before the United States House of Representatives. The three were elected state representatives for the progressive Mississippi Freedom Democratic Party. Devine helped found the party, and was a member of its delegation to the 1964 Democratic National Convention in New Jersey.
Document 4: Lynching of John Evans: On Tuesday, November 12, 1914, John Evans, a black man, was lynched in St. Petersburg, Florida, by a mob of 1,500 white men, women and children. Evans was accused of the murder of Edward Sherman, a white real estate developer, and the attack of Sherman’s wife, Mary. After word of the attack spread, and Mary Sherman claimed her attackers were “two negroes,” a citywide search ensued. Suspicions immediately led to John Evans. Two days after the murder, a posse consisting of some of the city’s most prominent and well-respected members stormed the St. Petersburg jail, threw a noose around Evan’s neck and marched him to his death. He was never given a fair trial. Evans was hung from a light post on the corner of Ninth Street South and Second Avenue. At first, Evans kept himself alive by wrapping his legs around the light pole. But then, an unidentified white woman in a nearby automobile ended his struggle with a single bullet. Though the shot was fatal, the rest of the crowd began shooting at Evan’s dangling body until their ammunition was depleted.
Document 5: Fannie Lou Hamer: Fannie Lou Hamer ( ; born Fannie Lou Townsend; October 6, 1917 – March 14, 1977) was an American voting rights activist, a leader in the Civil Rights Movement, and philanthropist who worked primarily in Mississippi.

Document 6: Joe Pullen: Joe Pullen or Joe Pullum (c. 1883 - December 15, 1923) was an African-American tenant farmer who was murdered by a lynch mob of local white citizens near Drew, Mississippi on December 15, 1923. While the circumstances that precipitated the violence were typical for that place and time, Pullen's case is unusual in that he managed to kill at least three members of the lynch mob and wound several others before ultimately perishing himself. Because of his courage, Pullen became a folk hero and his bravery was championed by the Universal Negro Improvement Association. While the incident received only brief national news coverage, the local repercussions were far more profound. As civil rights leader Fannie Lou Hamer recalled in an autobiographical essay on growing up in a nearby Mississippi town: "it was a while in Mississippi before the whites tried something like that again."
Document 7: Samuel Bowers: Samuel Holloway Bowers (August 25, 1924 – November 5, 2006), Former Ku Klux Klan Imperial Wizard, was a convicted murderer and leading white supremacist activist in Mississippi during the Civil Rights Movement.

Bowers committed two notorious murders of civil rights activists in southern Mississippi: The 1964 murders of Chaney, Goodman, and Schwerner near Philadelphia, for which he served six years in federal prison; and the 1966 murder of Vernon Dahmer in Hattiesburg, for which he was sentenced to life in prison 32 years after the crime. He also was accused of bombings of Jewish targets in the cities of Jackson and Meridian in 1967 and 1968 (according to the man who was convicted of some of the bombings, Thomas A. Tarrants III). He died in prison at the age of 82.

Dave Dennis worked closely with both Bob Moses and Medgar Evers as well as members of SNCC, the Student Nonviolent Coordinating Committee. Dennis' first involvement in the Civil Rights Movement was at a Woolworth sit-in organized by CORE and he went on to become a Freedom Rider in 1961. More recently Dennis has put his activism toward a new project, the Algebra Project, which is a nonprofit organization run by Bob Moses that aims to improve the mathematics education for minority children. Dennis also speaks about his experiences in the movement through an organization called Dave Dennis Connections.
Document 11: Robert Charles riots: The Robert Charles riots of July 24-27, 1900 in New Orleans, Louisiana were sparked after African American laborer Robert Charles fatally shot a white police officer and escaped arrest. A large manhunt for him ensued, and a white mob started rioting, attacking blacks throughout the city. The manhunt for Charles began after an altercation involving Charles, his roommate, and several New Orleans police officers on Monday, July 23, 1900, and ended when Charles was killed on Friday, July 27. A total of 28 people were killed in the riots, including Charles, shot by a special police volunteer. Other white men in the mob shot hundreds of bullets into his body and beat him beyond recognition. More than 50 people were wounded in the riots, including at least 11 who had to be hospitalized. Blacks made up most of the fatalities and casualties.

Martin Luther King, Jr. commonly referred to Clark as "The Mother of the Movement". Clark's argument for her position in the Civil Rights Movement was one that claimed "knowledge could empower marginalized groups in ways that formal legal equality couldn't."
