Communism (from Latin communis - common, universal) is a revolutionary socialist movement to create a classless, moneyless, and stateless social order structured upon common ownership of the means of production, as well as a social, political and economic ideology that aims at the establishment of this social order. This movement, in its Marxist-Leninist interpretations, significantly influenced the history of the 20th century, which saw intense rivalry between the "socialist world" (socialist states ruled by Communist parties) and the "western world" (countries with market economies), culminating in the Cold War between the Eastern bloc and the "Free World".^{[citation needed]}

In Marxist theory, pure communism is a specific stage of historical development that inevitably emerges from the development of the productive forces that leads to a superabundance of material wealth, allowing for distribution based on need and social relations based on freely associated individuals. The exact definition of communism varies, and it is often mistakenly, in general political discourse, used interchangeably with socialism; however, Marxist theory contends that socialism is just a transitional stage on the road to communism. Leninism adds to Marxism the notion of a vanguard party to lead the proletarian revolution and to secure all political power after the revolution for the working class, for the development of universal class consciousness and worker participation, in a transitional stage between capitalism and socialism.

Karl Heinrich Marx (5 May 1818 – 14 March 1883) was a German philosopher, economist, sociologist, historian, journalist, and revolutionary socialist. His ideas played a significant role in the development of social science and the socialist political movement. He published various books during his lifetime, with the most notable being The Communist Manifesto (1848) and Capital (1867–1894); some of his works were co-written with his friend and fellow German revolutionary socialist, Friedrich Engels.

Born into a wealthy middle class family in Trier, formerly in Prussian Rhineland now called Rhineland-Palatinate, Marx studied at both the University of Bonn and the University of Berlin, where he became interested in the philosophical ideas of the Young Hegelians. In 1836, he became engaged to Jenny von Westphalen, marrying her in 1843. After his studies, he wrote for a radical newspaper in Cologne, and began to work out his theory of dialectical materialism. Moving to Paris in 1843, he began writing for other radical newspapers. He met Engels in Paris, and the two men worked together on a series of books. Exiled to Brussels, he became a leading figure of the Communist League, before moving back to Cologne, where he founded his own newspaper. In 1849 he was exiled again and moved to London together with his wife and children. In London, where the family was reduced to poverty, Marx continued writing and formulating his theories about the nature of society and how he believed it could be improved, and also campaigned for socialism—he became a significant figure in the International Workingmen's Association.

Friedrich Engels (German pronunciation: [ˈfʁiːdʁɪç ˈɛŋəls]; 28 November 1820 – 5 August 1895) was a German-English industrialist, social scientist, author, political theorist, philosopher, and father of Marxist theory, alongside Karl Marx. In 1845 he published The Condition of the Working Class in England, based on personal observations and research. In 1848 he co-authored The Communist Manifesto with Karl Marx, and later he supported Marx financially to do research and write Das Kapital. After Marx's death Engels edited the second and third volumes. Additionally, Engels organized Marx's notes on the "Theories of Surplus Value" and this was later published as the "fourth volume" of Capital.

Friedrich (Frederick) Engels was born on November 28, 1820 in Barmen, Prussia (now Wuppertal, Germany). At the time, Barmen was an expanding industrial metropole and Frederick was the eldest son of a wealthy German cotton manufacturer. As his father, Friederich Sr., was a Methodist. Accordingly, Fredrick was raised Christian Pietist. As he grew up, his relationship with his parents became strained because of his atheist beliefs. Parental disapproval of his revolutionary activities is recorded in an October, 1848 letter from his mother, Elizabeth Engels. In this letter his mother berates him for having "really gone too far" and "begged" him "to proceed no further.". "You have paid more heed to other people, to strangers, and have taken no account of your mother's pleas. God alone knows what I have felt and suffered of late. I was trembling when I picked up the newspaper and saw therein that a warrant was out for my son's arrest." At the point this letter was written Frederick Engels was in hiding in Brussels, Belgium and was soon to make his way to Switzerland and then in 1849 make his way back into Germany to participate in the revolutionary uprising in Baden and Palatinate.

Nelson Rolihlahla Mandela (Xhosa pronunciation: [xoˈliːɬaɬa manˈdeːla]; born 18 July 1918) is a South African politician who served as President of South Africa from 1994 to 1999, the first ever to be elected in a fully representative democratic election. Before being elected President, Mandela was a militant anti-apartheid activist, and the leader and co-founder of Umkhonto we Sizwe, the armed wing of the African National Congress (ANC). In 1962 he was arrested and convicted of sabotage and other charges, and sentenced to life imprisonment. Mandela went on to serve 27 years in prison, spending many of these years on Robben Island. Following his release from prison on 11 February 1990, Mandela led his party in the negotiations that led to the establishment of democracy in 1994. As President, he frequently gave priority to reconciliation, while introducing policies aimed at combating poverty and inequality in South Africa.

In South Africa, Mandela is often known as Madiba, his Xhosa clan name; or as tata (Xhosa: father). Mandela has received more than 250 awards over four decades.
