What significant milestone for women's rights occurred in 1928 in the UK?

In 1928, a significant milestone for women's rights in the UK was the achievement of voting equality, as women aged 21 and over were granted the right to vote. This was a monumental moment in the history of women's suffrage, as it marked the culmination of decades of activism and struggle for voting rights that had begun in earnest in the late 19th century.

Prior to this change, women had gained the right to vote in 1918, but this was limited to those over the age of 30 who met certain property qualifications. The 1928 Representation of the People Act extended the franchise to all women over the age of 21, putting them on equal footing with men, who had the right to vote at 21 without property restrictions. This advancement not only empowered women politically but also represented a shift in societal attitudes towards gender equality.

The other options, while related to women's rights, do not reflect the specific achievement that took place in 1928. The right to own property, work in all jobs, or serve in the military were subjects of ongoing advocacy but were not bound to that particular year. Thus, the granting of the vote to women over 21 is the defining milestone of that period.
