Statehood began with the 13 original colonies, which became states through ratification of the Constitution. From the late 1700s through the 1800s, new states were admitted after westward expansion, corresponding land purchases, and Antebellum era considerations, including the pairing of free and slave states to preserve Senate balance.
In the late 1800s, gold rushes and the transcontinental railroad resulted in fast-tracked statehood for territories in the Midwest, Rocky Mountains, and on the Pacific coast.
In the 1900s, the final states followed more distinct paths, including New Mexico and Arizona after territorial delays and Alaska and Hawaii as non-contiguous territories admitted due to strategic and political considerations.
Alaska and Hawaii
Both were non-contiguous territories admitted in 1959 after debates surrounding culture, political balance, national security, and full voting representation. Alaska’s admission stemmed from local demands for equal citizenship paired with federal interest in defense strategy and natural resources. Hawaii’s admission post-annexation relied on strong local support for voting rights and a desire to demonstrate loyalty after World War 2, alongside federal recognition of its strategic Pacific location. However, delays centered on incorporating a multiethnic territory with a distinct identity, much like Puerto Rico. After statehood, Hawaii maintained its cultural identity by outlining state constitutional protections that preserve the Hawaiian language and traditional practices.
New Mexico and Arizona
Both territories faced long admission delays due to congressional concerns over sparse population, partisan balance, and cultural assimilation, including the failed Jointure Plan to admit them as a single state, which Arizona voters rejected. Eventually, population increases and diverging political preferences led to their statehood. Much like Puerto Rico, cultural concerns were central to the debate, especially concerning New Mexico’s Catholic and Spanish-speaking population. After admission, New Mexico retained its identity and its state constitution included explicit protections for Spanish-speaking citizens and laws were published in both English and Spanish.
Texas
Texas was an independent republic before joining the Union in 1845. Its admission reflected both local support and U.S. interest in expansion, and its strong state identity continued after statehood alongside an American national identity.
The Bottom Line
Statehood has followed different paths, but the key themes are consistent. Local support and federal interests matter, but Congress makes the final decision. Admission has reflected political balance, strategic value, economic potential, and questions about incorporating different cultures. Once admitted, states retain their own constitutions and governments within the federal system, alongside distinct identities that preserve their cultural and historical roots.
