Denmark amends its constitution to allow women's suffrage.

The Constitutional Act of the Realm of Denmark, also known as the Constitutional Act of the Kingdom of Denmark, or simply the Constitution, is the constitution of the Kingdom of Denmark, applying equally in the Realm of Denmark: Denmark proper, Greenland and the Faroe Islands. The first democratic constitution was adopted in 1849, replacing the 1665 absolutist constitution. The current constitution is from 1953. The Constitutional Act has been changed a few times. The wording is general enough to still apply today.

Women's suffrage is the right of women to vote in elections. Several instances occurred in recent centuries where women were selectively given, then stripped of, the right to vote. In Sweden, conditional women's suffrage was in effect during the Age of Liberty (1718–1772), as well as in Revolutionary and early-independence New Jersey (1776–1807) in the US.
