Universal suffrage
The Parliament of Finland was preceded by the Diet of Finland (; , modern ), which had succeeded the Riksdag of the Estates in 1809. When the unicameral Parliament of Finland was established by the Parliament Act in 1906, Finland was an autonomous grand duchy and principality under the Imperial Russian Tsar, who ruled as the Grand Duke, rather than as an absolute monarch. Universal suffrage and eligibility was implemented, making Finland the second country in the world to adopt universal suffrage. Women could both vote and run for office as equals, and this applied also to landless people, with no excluded minorities. The first election to the Parliament was arranged in 1907. The first Parliament had 19 female representatives, an unprecedented number at the time, which grew to 21 by 1913.
