Final answer:
England experienced significant political changes in the 19th century with legal reforms expanding civil rights and representation, abolishing slavery, and liberalizing the government, all while avoiding a revolution and maintaining power in Europe.
Step-by-step explanation:
In England, the 19th century was marked by a series of political developments designed to avoid revolution and reform various systemic inequalities. The significant changes began in the 1820s with acts allowing Catholics and non-Anglicans to hold office, followed by the landmark Great Reform Bill of 1832 which broadened the electorate and eradicated 'rotten boroughs'. Subsequent legislation included the abolition of slavery, the introduction of the Poor Laws, the reform of city governments, and the 1846 repeal of the Corn Laws, reflecting a gradual move towards a more liberalized government.
