When did North Dakota South Dakota and Washington become states?

Answer 1

North Dakota and South Dakota were both part of the Dakota Territory. They became separate states on November 2, 1889, when President Harrison signed the law making them the 39th and 40th states of the United States.

President Benjamin Harrison had the statehood papers shuffled and did not know which he was signing first, nor was it recorded, hence they became states "simultaneously".

Answer 3

The Enabling Act of 1889 split the Dakota Territory in half to create two potential states and was passed on 22 February 1889.

Washington was admitted to the union on November 11, 1889 as the 42nd state.
