Connecticut at a glance
Connecticut was admitted to the Union on 1788, making it the 4th state. As one of the original 13 colonies, Connecticut was a founding member of the United States. Its capital Hartford has been the seat of state government for most of the state's history.
Native peoples
For thousands of years before European contact, Indigenous peoples lived across what is now Connecticut. Multiple distinct cultures developed in response to the region's geography — coastal peoples, plains peoples, river-valley peoples, mountain peoples — each with their own languages, governance, and trade networks. European colonization disrupted these civilizations dramatically, often through disease, displacement, and forced removal. Today, Connecticut's Native heritage is preserved in place names, tribal nations within state borders, and ongoing cultural practices.
Colonial era and Revolution
As one of the 13 original colonies, Connecticut was central to the founding of the United States. British colonization of the region began in the 17th century. By the 1770s, colonial assemblies were resisting British taxation policies, and Connecticut sent delegates to the Continental Congress that declared independence in 1776. Connecticut fought in the Revolutionary War alongside the other 12 colonies and ratified the US Constitution between 1787 and 1790, depending on the specific date.
Path to statehood
The path from European exploration to statehood typically took decades. Connecticut was already an established colony when the US declared independence in 1776, becoming a state with the ratification of the US Constitution by 1788.
The modern era
Today Connecticut has a population of 1 to 5 million and is one of the smallest states in the country. The capital is Hartford; the largest city is Bridgeport. The political lean has shifted over time and now leans reliably Democratic.
