The major political reform movement that emerged in the United Kingdom during the 19th century was the Chartist movement. Originating in the 1830s and peaking in the 1840s, the movement sought to expand voting rights to the working class and promote political equality. This grassroots effort produced the People's Charter of 1838, which outlined six key demands, including universal male suffrage, secret ballots, and annual Parliaments. Although the Chartist movement did not achieve immediate success, it laid the groundwork for future reforms and served as an important precursor to the broader suffrage movements, ultimately influencing significant changes in British democracy over time.
