Conflict theories are perspectives in social science that emphasize the social, political or material inequality of a social group, that critique the broad socio-political system, or that otherwise detract from structural functionalism and ideological conservativism. Conflict theories draw attention to power differentials, such as class conflict, and generally contrast historically dominant ideologies. It is therefore a macro level analysis of society. Karl Marx is the father of the social conflict theory, which is a component of the 4 paradigms of sociology.^{[citation needed]}

Certain conflict theories set out to highlight the ideological aspects inherent in traditional thought. Whilst many of these perspectives hold parallels, conflict theory does not refer to a unified school of thought, and should not be confused with, for instance, peace and conflict studies, or any other specific theory of social conflict.

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.
