In which year did women gain the vote in Britain?

Women in Britain gained the right to vote in 1918. This milestone was achieved with the passage of the Representation of the People Act, which allowed women over the age of 30 who met certain property qualifications to vote. This was a significant development in the history of women's rights in the UK, marking the culmination of decades of campaigning for suffrage.

While the other years mentioned correspond to various events in history, they do not represent the point at which women formally gained the right to vote. For instance, 1920 does not align with the UK context as it is often associated with women's suffrage in other countries, particularly the United States. The years 1935 and 1945 are also incorrect as they relate to other legislative changes and events, rather than the initial victory for women's suffrage in Britain. Thus, 1918 is the pivotal year that recognized women's voting rights in the UK.
