Hartford is the capital of the U.S. state of Connecticut and the historic seat of Hartford County until Connecticut disbanded county government in 1960. As of the 2010 Census, Hartford's population was 124,775, making it Connecticut's third-largest city after the coastal cities of Bridgeport and New Haven. Nicknamed the 'Insurance Capital of the World', Hartford houses many insurance company headquarters, and insurance remains the region's major industry. Almost 400 years old, Hartford is among the oldest cities in the United States. Following the American Civil War, Hartford was the wealthiest city in the United States for several decades. In 1868, Mark Twain wrote before he died, 'Of all the beautiful towns it has been my fortune to see this is the chief.' Today, Hartford is one of the poorest cities in the nation with 3 out of every 10 families living below the poverty line.
