North Dakota's official state motto 'Liberty and union, now and forever, one and inseparable' was adopted as an element of its official seal in 1889.
The motto of Dakota Territory was Liberty and Union, One and Inseparable, Now and Forever. This language was suggested by
Dr. Joseph Ward of Yankton, South Dakota, who was quoting from Daniel Webster's Reply to Hayne. However, the motto used for the Territory had two of
the phrases reversed; when North Dakota became a state that error was corrected.
These states have mottos that focus on liberty.
These state have mottos that reference the union:
The law designating the official North Dakota state motto is found in the North Dakota Constitution, Article 9, Section 2.
