By the mid-1800s, political attitudes began to shift towards allowing the working class, especially artisans, the right to vote, influenced by liberalism and socialism. Political thinkers like John Stuart Mill and Karl Marx advocated for these changes, while the creation of trade unions and pressure groups highlighted the organized political involvement of the working class. Despite these changes, significant portions of the population remained disenfranchised, and instances of violence at protests undermined the perceived respectability of the working class.
