Proletariats refer to the working class in a capitalist society, particularly those who do not own the means of production and sell their labor for wages. This class emerged prominently during the Industrial Revolution, becoming a key focus in discussions about economic and social inequalities as they faced harsh working conditions, low wages, and limited rights. Understanding the role of proletariats is essential to grasping the broader impacts of industrialization on society and the political movements that arose in response to their struggles.
