The region of the State was colonized by Swedes and Dutch, and later passed into British control. Pennsylvania was one of thirteen colonies that rebelled in the United States War of Independence, and, in fact, has great historical importance for the country, since the declaration of independence and the American constitution were created on its soil.

A well-known nickname of the state is The Keystone State, a reference to its geographical location. In fact, Pennsylvania is located in a strategic region. The State is the only one among the former thirteen colonies that have no coastline. Allegheny, Monongahela, Ohio and Delaware are its main rivers. The predominant climate in Pennsylvania is temperate, with average temperatures of 21ºC in the summer and -2.8ºC in the winter.

Until the 1970s, the state’s economy was entirely based on the steel industry. Although still the largest steel hub in the United States, Pennsylvania has started to diversify its economy after a major economic recession between the 1970s and 1980s. Currently, the largest sources of wealth for the state are trade and oil production, processed foods, chemicals and electronics.
