About Delaware

Delaware is one of the 50 states of the United States, in the Mid-Atlantic or Northeastern region. The state’s total area is 2,044 sq mi (5,295 sq km), of which land takes up 1,932 sq mi (5,005 sq km) and inland water, 112 sq mi (290 sq km). Delaware declared its independence from Great Britain on June 15, 1776. It thereby also became independent of Pennsylvania with which it had been connected since 1682. According to legend, Delaware was nicknamed “The Diamond State” because Thomas Jefferson referred to it as a “jewel among the states” due to its prime location on the Eastern Seaboard. Delaware is the only state in the US without any national parks.
