2. On November 22, 1915, a group of suffragists marched through Pierre to demand that women be granted the right to vote. The activists, who came from across the state, were part of a larger national movement that eventually led to the adoption of the 19th Amendment in 1920.

3. In 1963, South Dakota's Governor Archie Gubbrud proclaimed a statewide day of mourning in honor of President John F. Kennedy, who had been assassinated in Dallas just one day earlier. The proclamation called on all South Dakotans to observe a moment of silence and to lower their flags to half-staff.

4. On November 22, 1975, the Crazy Horse Memorial in the Black Hills region of South Dakota was dedicated. The memorial, which honors the Lakota warrior and leader Crazy Horse, is one of the largest sculptures in the world and has become a major tourist attraction.

5. In 1986, South Dakota voters approved a constitutional amendment that allowed casinos to be built in Deadwood, a historic gold-mining town in the Black Hills. The amendment paved the way for a major expansion of the town's gaming industry, which has since become an important part of the state's economy.
