Final answer:
The major reform acts of 1832, 1867, and 1884-85 in Great Britain aimed to broaden suffrage and make the political system more inclusive by expanding the electorate to the middle and working classes and abolishing corrupt practices like 'rotten boroughs.'
Step-by-step explanation:
Purpose of the Three Major Reform Acts in Great Britain
The specific purpose of the three major reform acts in Great Britain, passed in 1832, 1867, and 1884-85, was to expand suffrage and make the political system more representative and democratic. The Great Reform Act of 1832 was initiated due to the demands of the middle class and the fear of revolution; it expanded the electorate to include a majority of the urban middle class and abolished the 'rotten boroughs.'
The Reform Act of 1867, led by Benjamin Disraeli and the modern Conservative Party, extended the right to vote to many working-class men, thereby doubling the size of Britain's electorate and continuing the trend of broadening democratic participation.
Last, the Reform Act of 1884-85 further democratized the political system by extending voting rights, leading to the inclusion of a larger portion of the working class in the political process, which was a significant step towards universal suffrage.
