Approval in Washington
On 30 May 1854, President Franklin Pierce approved the congressional act formally titled "An Act to Organize the Territories of Nebraska and Kansas," making it law.
Congress had passed it days earlier: the Senate by 37–14 after an all-night session, the House by 113–100 on 22 May. Stephen A. Douglas had introduced and managed the bill, accepting explicit repeal of the Missouri Compromise restriction to hold southern support.
The statute created separate temporary governments for Nebraska Territory and Kansas Territory, with boundaries and executive, legislative and judicial offices prescribed by Congress.
The clause that voided the 1820 line
For each territory the law declared the Missouri Compromise's restriction on slavery "inoperative and void," and said the people were to regulate their domestic institutions subject to the Constitution.
This was not a repeal of the entire 1820 statute — it targeted the eighth-section restriction, which had applied to Louisiana Purchase territory north of 36°30′ except Missouri.
The act's franchise for each territory's first election reached only actual resident free white male inhabitants over twenty-one, subject to citizenship or declared-intention requirements.
What did not happen that day
No territorial popular vote took place on 30 May. Self-government under the act would run through territorial elections, legislatures and constitution-making, amid disputes over who was entitled to vote.
The statute did not ignore Indigenous treaties: it preserved existing treaty rights and withheld unconsented treaty-protected lands from the new territories' jurisdiction.
Bleeding Kansas, the realignment of the parties and the war that followed were later consequences, separated from the signing by years of intervening politics and violence.
