It happened first in 1893 in New Zealand, later in 1918 in Britain, 1920 in the United States, and only 1971 in Switzerland. What was it?

The long and difficult struggle for a fundamental democratic right unfolded at a vastly different pace around the world. The timeline in the question charts key milestones in the women's suffrage movement. New Zealand became the first self-governing country to grant all women the right to vote in national elections in 1893, setting a global precedent after decades of activism by figures like Kate Sheppard.

However, these dates often hide a more complex reality. In Britain, the 1918 act only enfranchised women over 30 who met a property qualification; full universal suffrage for women didn't arrive until 1928. Similarly, while the 19th Amendment was ratified in the U.S. in 1920, voter suppression tactics meant that many women of color were effectively barred from exercising that right for decades more.

Switzerland's late adoption in 1971 is particularly striking. Its system of direct democracy required the country's all-male voting population to approve the change in a federal referendum, which they had rejected as recently as 1959. These varied timelines highlight that the path to equal political participation was not a single global event, but a series of hard-fought national and local battles that spanned nearly a century.
