Final answer:
In 1912, Prime Minister Giovanni Giolitti had the Italian Parliament approve Universal Male Suffrage, which expanded voting rights to practically all adult males.
Step-by-step explanation:
In 1912, under the leadership of Prime Minister Giovanni Giolitti, the Italian Parliament approved a significant electoral reform known as Universal Male Suffrage. This reform expanded the right to vote to all male citizens who were at least 30 years old or who had completed military service, significantly increasing the electorate from about half a million to practically all adult males. Prior to this reform, the electorate was limited to property owners, and Giolitti's move was part of a broader effort to modernize Italy and integrate it more thoroughly into the fabric of Europe's parliamentary democracies. This was a step forward in democratizing the country and involving more citizens in the political process.
