Mississippi at a glance
Mississippi was admitted to the Union on 1817, making it the 20th state. It joined the country 41 years after the Declaration of Independence. Its capital Jackson has been the seat of state government since well before the Civil War.
Native peoples
For thousands of years before European contact, Indigenous peoples lived across what is now Mississippi. 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, Mississippi's Native heritage is preserved in place names, tribal nations within state borders, and ongoing cultural practices.
Civil War (1861-1865)
Mississippi seceded from the United States and joined the Confederate States of America during the American Civil War. The war devastated the state economy, with widespread destruction and loss of life. After Confederate defeat in 1865, Mississippi entered the long Reconstruction era, which sought to integrate formerly enslaved people into civic and economic life. Reconstruction officially ended in 1877. The state's path to full re-integration into the Union — economically, politically, and socially — extended well into the 20th century, particularly through the Civil Rights Movement of the 1950s-60s.
Path to statehood
The path from European exploration to statehood typically took decades. Mississippi was admitted to the Union on 1817, after meeting the requirements set by Congress: sufficient population, a written constitution, and the consent of Congress. The process from initial settlement to statehood was the 31st time the US expanded.
The modern era
Today Mississippi has a population of 1 to 5 million and is one of the mid-sized states in the country. The capital is Jackson; the largest city is Jackson. Agriculture remains an important sector of the state economy. The political lean has shifted over time and now leans reliably Republican.
