1. Formation of North Dakota: February 1, 1889, marked an important day in North Dakota's history as it became the 39th state of the United States. The state was formed after being separated from the Dakota Territory, which became two separate states, North and South Dakota.

2. First Women's Suffrage State: North Dakota became the first U.S. state to grant women the right to vote in 1890, just one year after it became a state. This progressive move paved the way for other states to follow suit and eventually led to the 19th Amendment granting women the right to vote nationally in 1920.

3. Blizzard of 1991: On February 1, 1991, North Dakota experienced one of the worst blizzards in its history. The storm caused power outages, destroyed homes, and left many stranded in their cars. The state declared a state of emergency and the National Guard was mobilized to assist with rescue and recovery efforts.

4. International Peace Garden: The International Peace Garden, located on the border of North Dakota and Manitoba, Canada, was established on February 1, 1932. The garden serves as a symbol of peace and friendship between the two nations and includes a lush botanical garden and a 9/11 memorial.

5. Theodore Roosevelt National Park: On February 1, 1978, the Theodore Roosevelt National Park in North Dakota was officially established. The park celebrates the life and legacy of President Theodore Roosevelt, who spent time in the state during his youth and is known for his conservation efforts as president. The park is home to a variety of wildlife, including bison, elk, and pronghorn.
