A communist party is a political party that seeks to realize the socio-economic goals of communism. The term communist party was popularized by the title of The Manifesto of the Communist Party (1848) by Karl Marx and Friedrich Engels. As a vanguard party, the communist party guides the political education and development of the working class (proletariat). As a ruling party, the communist party exercises power through the dictatorship of the proletariat. Vladimir Lenin developed the idea of the communist party as the revolutionary vanguard, when the socialist movement in Imperial Russia was divided into ideologically opposed factions, the Bolshevik faction ("of the majority") and the Menshevik faction ("of the minority"). To be politically effective, Lenin proposed a small vanguard party managed with democratic centralism which allowed centralized command of a disciplined cadre of professional revolutionaries. Once a policy was agreed upon, realizing political goals required every Bolshevik's total commitment to the agreed-upon policy.

In contrast, the Menshevik faction, which initially included Leon Trotsky, emphasized that the party should not neglect the importance of mass populations in realizing a communist revolution. In the course of the revolution, the Bolshevik party which became the Communist Party of the Soviet Union (CPSU) assumed government power in Russia after the October Revolution in 1917. With the creation of the Communist International (Comintern) in 1919, the concept of communist party leadership was adopted by many revolutionary parties, worldwide. In an effort to standardize the international communist movement ideologically and maintain central control of the member parties, the Comintern required that its members use the term "communist party" in their names.

Under the leadership of the CPSU, the interpretations of orthodox Marxism were applied to Russia and led to the emergence of Leninist and MarxistLeninist political parties throughout the world. After the death of Lenin, the Comintern's official interpretation of Leninism was the book Foundations of Leninism (1924) by Joseph Stalin.

Helen Adams Keller (June 27, 1880 – June 1, 1968) was an American author, disability rights advocate, political activist and lecturer. Born in West Tuscumbia, Alabama, she lost her sight and her hearing after a bout of illness at the age of 19 months. She then communicated primarily using home signs until the age of seven when she met her first teacher and life-long companion Anne Sullivan, who taught her language, including reading and writing; Sullivan's first lessons involved spelling words on Keller's hand to show her the names of objects around her. She also learned how to speak and to understand other people's speech using the Tadoma method. After an education at both specialist and mainstream schools, she attended Radcliffe College of Harvard University and became the first deafblind person to earn a Bachelor of Arts degree. She worked for the American Foundation for the Blind (AFB) from 1924 until 1968, during which time she toured the United States and traveled to 35 countries around the globe advocating for those with vision loss.

Keller was a prolific author, writing 14 books and hundreds of speeches and essays on topics ranging from animals to Mahatma Gandhi. Keller campaigned for those with disabilities, for women's suffrage, labor rights, and world peace. She joined the Socialist Party of America in 1909. She was a supporter of the NAACP and an original member of the American Civil Liberties Union. In 1933, when her book How I Became a Socialist was burned by Nazi youth, she wrote an open letter to the Student Body of Germany condemning censorship and prejudice.

The story of Keller and Sullivan was made famous by Keller's 1903 autobiography, The Story of My Life, and its adaptations for film and stage, The Miracle Worker. Her birthplace is now a museum and sponsors an annual "Helen Keller Day". Her June 27 birthday is commemorated as Helen Keller Day in Pennsylvania and, in the centenary year of her birth, was recognized by a presidential proclamation from U.S. President Jimmy Carter.

She was inducted into the Alabama Women's Hall of Fame in 1971 and was one of twelve inaugural inductees to the Alabama Writers Hall of Fame on June 8, 2015.
