November 2, 1889 North Dakota and South Dakota Admitted as States

On November 2, 1889, you can trace the moment President Benjamin Harrison admitted North Dakota and South Dakota into the Union as the 39th and 40th states. Harrison famously shuffled the documents before signing so neither state could claim precedence over the other. Their admission was driven by Republican strategy, regional tensions, and railroad influence that had been building for years. There's much more to this story than a single signature.

Key Takeaways

• On November 2, 1889, President Benjamin Harrison signed proclamations admitting North Dakota and South Dakota as the 39th and 40th states.
• Harrison shuffled the signing documents so neither state could claim precedence over the other in admission order.
• Both states were authorized through the Omnibus Enabling Act, signed February 22, 1889, which allowed separate constitutional conventions.
• Republicans strategically supported creating two states instead of one, gaining four Senate seats rather than two.
• North Dakota chose Bismarck as its capital, while South Dakota designated Pierre, reflecting longstanding regional rivalries within the former territory.

The Dakota Territory That Became Two States

When Congress created the Dakota Territory in 1861, it covered a vast stretch of the northern Great Plains that once included present-day Montana and Wyoming. In 1868, the territory shrank to the land that would eventually become North Dakota and South Dakota.

As settlers pushed into the region, they displaced Native settlements and accelerated Indigenous displacement that reshaped the territorial landscape. To the north, Canadian prairie territories were simultaneously being opened through a series of seven numbered treaties that ceded vast Indigenous lands in exchange for modest annual payments of $5 per person. Population growth created a sharp divide between the northern and southern regions, fueling disagreements over governance, regional leadership, and capital location. You can trace this tension directly to the eventual split.

Why the Push for Separate Statehood Gained Momentum

The regional divide that made a unified Dakota Territory unworkable didn't emerge overnight—it built steadily through competing interests, population pressures, and national party strategy. As settlement expanded, economic pressures intensified disagreements over taxation, infrastructure, and where political power should sit. Northern and southern residents had developed distinct local identities, and neither side wanted the other controlling a shared capital.

Republicans in Congress saw an opportunity. Splitting the territory meant four new Senate seats instead of two, strengthening their national majority. That political incentive aligned neatly with what settlers already wanted—self-governance rooted in their own communities. You can see how both practical and partisan forces pushed in the same direction. By 1889, the case for two separate states had become impossible to ignore. This kind of deliberate constitutional structuring had precedent in Canada's 1867 framework, where the bicameral legislature balanced elected and appointed chambers to distribute political power across competing regional interests.

The Omnibus Enabling Act and the Road to Admission

Signed into law on February 22, 1889, the Omnibus Enabling Act gave Dakota inhabitants the formal authority to draft their own constitutions and pursue statehood. You can think of this legislation as the critical turning point that transformed political ambition into a structured legal process.

Separate constitutional conventions convened in both northern and southern Dakota, with delegates tackling constitution drafting under intense scrutiny. Legal controversies surfaced during the process, as competing regional interests complicated negotiations over governance structures and representation. Despite these tensions, both conventions produced ratified constitutions and submitted them for presidential approval.

President Benjamin Harrison reviewed the submissions and issued proclamations declaring that admission conditions were fully satisfied. That decision officially set November 2, 1889, as the date both territories would enter the Union as independent states. Similarly, governments formalize critical financial operations through structured legislation, as seen when Canada passed its Borrowing Authority Act in 1996 to authorize federal borrowing within approved limits for the 1996–97 fiscal year.

Why Republicans Pushed to Split the Dakota Territory

Behind Harrison's proclamations and the constitutional process lay a sharp political calculation that shaped how Dakota's division unfolded. Republicans knew that splitting Dakota Territory into two states meant four new Senate seats instead of two, and they intended to fill them with party loyalists. You can trace patronage politics throughout the entire statehood push—from candidate selection to capital placement decisions in Bismarck and Pierre.

Railroad influence also played a measurable role. Rail companies had economic stakes in how boundaries and capitals were drawn, and they backed politicians who protected their interests. Republicans aligned with those forces to accelerate admission before any Democratic shift in Congress could block the move. The split wasn't simply geographic convenience—it was a deliberate strategy to lock in Senate power for a generation. Similar to how Canada awarded the CPR 25 million acres along the railway right-of-way to incentivize transcontinental construction, American railroad companies extracted favorable terms from politicians eager to secure their backing for statehood.

November 2, 1889: The Day the Dakotas Entered the Union

On November 2, 1889, President Benjamin Harrison signed two separate proclamations that brought North and South Dakota into the Union simultaneously, making them the 39th and 40th states. Harrison reportedly shuffled the documents before signing so neither state could claim precedence over the other.

Statehood ceremonies took place across both territories, with residents gathering to mark the shift from territorial rule to full representation in Congress. Local reactions reflected genuine pride, as communities in Bismarck and Pierre celebrated the formal recognition of their respective capitals.

You can imagine the excitement felt by settlers who'd spent years pushing for self-governance. The day closed the Dakota Territory era permanently and gave both states the political standing they'd long pursued. Centuries later, questions of political recognition and identity would continue to shape North American governance, as seen when the Canadian House of Commons passed a motion 265 to 16 recognizing the Québécois as a nation within a united Canada in 2006.

How the Dakotas Developed in the Years After Statehood

Statehood quickly transformed North and South Dakota, as rail expansion pushed deeper into the plains and drew thousands of new settlers to both states.

You'd have witnessed dramatic agricultural mechanization reshape farming practices, replacing manual labor with machinery that dramatically increased crop yields across vast stretches of land.

Towns grew rapidly around rail depots, and wheat farming became the economic backbone of both states.

South Dakota developed a strong ranching industry alongside its agricultural sector, while North Dakota leaned heavily into grain production.

Decades later, oil discovery in western North Dakota further shifted the state's economic identity, unleashing underground wealth that settlers never anticipated.

These developments built on the foundation that statehood provided, turning two young territories into resilient, economically diverse states within the American heartland. In Canada, the post-war era similarly prompted cultural reflection, leading to the formal Historic Sites and Monuments Act of 1953, which codified federal responsibility for recognizing places, persons, and events of national historic significance.
