Working class in the context of "Middle class"

Social stratification refers to a society's categorization of its people into groups based on socioeconomic factors like wealth, income, race, education, ethnicity, gender, occupation, social status, or derived power (social and political). It is a hierarchy within groups that ascribe them to different levels of privileges. As such, stratification is the relative social position of persons within a social group, category, geographic region, or social unit.

In modern Western societies, social stratification is defined in terms of three social classes: an upper class, a middle class, and a lower class; in turn, each class can be subdivided into an upper-stratum, a middle-stratum, and a lower stratum. Moreover, a social stratum can be formed upon the bases of kinship, clan, tribe, or caste, or all four.

A social class or social stratum is a grouping of people into a set of hierarchical social categories, the most common ones being: the working class, the middle class and the upper class. Membership of a social class is commonly considered dependent on education, wealth, occupation, income, and belonging to a particular subculture or social network.

Class is a subject of analysis for sociologists, political scientists, anthropologists and social historians. The term has a wide range of sometimes conflicting meanings, and there is no broad consensus on a definition of class. Some people argue that due to social mobility, class boundaries do not exist. In common parlance, the term social class is usually synonymous with socioeconomic class, defined as "people having the same social, economic, cultural, political or educational status", e.g. the working class, "an emerging professional class" etc. However, academics distinguish social class from socioeconomic status, using the former to refer to one's relatively stable cultural background and the latter to refer to one's current social and economic situation which is consequently more changeable over time.

The Russian Revolution was a period of political and social change in Russia, starting in 1917. This period saw Russia abolish its monarchy and adopt a socialist form of government following two successive revolutions and a civil war. It can be seen as the precursor for other revolutions that occurred in the aftermath of World War I, such as the German Revolution of 1918–1919. The Russian Revolution was a key event of the 20th century.

The Russian Revolution was inaugurated with the February Revolution in 1917, in the midst of World War I. With the German Empire inflicting defeats on the front, and increasing logistical problems causing shortages of bread and grain, the Russian Army was losing morale, with large scale mutiny looming. Officials were convinced that if Tsar Nicholas II abdicated, the unrest would subside. Nicholas stepped down on 15 March [O.S. 2 March], ushering in a provisional government led by the Duma (parliament). During the unrest, Soviet councils were formed by locals in Petrograd (now Saint Petersburg) that initially did not oppose the new government; however, the Soviets insisted on their influence in the government and control over militias. By March, Russia had two rival governments. The Provisional Government held state power in military and international affairs, whereas the network of Soviets held domestic power. Critically, the Soviets held the allegiance of the working class, and urban middle class. There were mutinies, protests and strikes. Socialist and other leftist political organizations competed for influence within the Provisional Government and Soviets. Factions included the Mensheviks, Social Revolutionaries, Anarchists, and the Bolsheviks, a far-left party led by Vladimir Lenin.

Upper class in modern societies is the social class composed of people who hold the highest social status. Usually, these are the wealthiest members of class society, and wield the greatest political power. According to this view, the upper class is generally distinguished by immense wealth which is passed on from generation to generation. Prior to the 20th century, the emphasis was on aristocracy, which emphasized generations of inherited noble status, not just recent wealth.

Because the upper classes of a society may no longer rule the society in which they are living, they are often referred to as the old upper classes, and they are often culturally distinct from the newly rich middle classes that tend to dominate public life in modern social democracies. According to the latter view held by the traditional upper classes, no amount of individual wealth or fame would make a person from an undistinguished background into a member of the upper class as one must be born into a family of that class and raised in a particular manner to understand and share upper class values, traditions, and cultural norms. The term is often used in conjunction with terms like upper-middle class, middle class, and working class as part of a model of social stratification.

In political science, the term class struggle, class conflict, or class war refers to the economic antagonism and political tension that exist among social classes because of clashing interests, competition for limited resources, and inequalities of power in the socioeconomic hierarchy. In its simplest manifestation, class struggle refers to the conflict between classes within class systems .

In the writings of several leftist, socialist, and communist theorists, notably those of Karl Marx, class struggle is a core tenet and a practical means for effecting radical sociopolitical transformations for the majority working class. It is also a central concept within conflict theories of sociology and political philosophy.

Marxist historiography, or historical materialist historiography, is an influential school of historiography. The chief tenets of Marxist historiography include the centrality of social class, social relations of production in class-divided societies that struggle against each other, and economic constraints in determining historical outcomes (historical materialism). Marxist historians follow the tenets of the development of class-divided societies, especially modern capitalist ones.

Marxist historiography has developed in varied ways across different regional and political contexts. It has had unique trajectories of development in the West, the Soviet Union, and in India, as well as in the pan-Africanist and African-American traditions, adapting to these specific regional and political conditions in different ways. Marxist historiography has made contributions to the history of the working class, and the methodology of a history from below.
