allowing women to vote

Explanation:

New Zeland was the pioneer of social change in the world.

Back in 1893, New Zealand became the first self-governing country ever to give all women the right to vote. The suffragettes of New Zeland were the ones who fought and urged for this basic right for years. It resulted in change which many of the countries did not introduce until the beginning of the 20th century and the end of World War I.

Another social change in New Zealand occurred in 1898. when Richard Seddon introduced the welfare system with the settling of state pensions. The amount the state gave the old people was not big, but it was the first pension department in the world, and the first one to give all citizens above the age of 65, no matter of their ethnicity and gender, some basic income.

In 1930. New Zeland also became first in introducing a state housing program that offered workers low-rent housing that fulfilled basic needs.
