Answer: Pitcairn Islands
Many areas in the world have had women's partial or universal suffrage from time to time but removed it later. Pitcairn Islands became a British colony in 1836, with a degree of autonomy and local government, and had universal women's suffrage which is still in force. New Zealand instituted universal women's suffrage in 1893, and South Australia in 1894. In 1906 the Grand Duchy of Finland became the place with the longest record in the world of giving women full political rights, i.e. both the right to vote and to run for office, and the first in Europe to give women the right to vote; the world's first female members of parliament were elected in Finland the following year.
