In April 2001, Dongguan and Hartford, United States, formally signed a sister city relationship agreement, and Hartford became the first international sister city of Dongguan.
Hartford is the capital city of the U.S. state of Connecticut. It was the seat of Hartford County until Connecticut disbanded county government in 1960. The city is nicknamed the "Insurance Capital of the World", as it hosts many insurance company headquarters which is the region's major industry.
Hartford was founded in 1635 and is among the oldest cities in the United States. It is home to the nation's oldest public art museum (Wadsworth Atheneum), the oldest publicly funded park (Bushnell Park), the oldest continuously published newspaper (the Hartford Courant), and the second-oldest secondary school (Hartford Public High School). It also is home to Trinity College, a private liberal arts college, and the Mark Twain House where the author wrote his most famous works and raised his family, among other historically significant attractions. Mark Twain wrote in 1868, "Of all the beautiful towns it has been my fortune to see this is the chief."
