Harrisburg is the capital of Pennsylvania, one of four states designated a Commonwealth of the United States. As of the 2000 census, the city has a total population of 48,950 (metropolitan area 643,820), making it the fourth largest metropolitan area in Pennsylvania. Harrisburg is the county seat of Dauphin County and lies on the banks of the Susquehanna River, 105 miles (169 km) west by north of Philadelphia.
Harrisburg is one of the oldest and most historically significant state capital cities in the United States. It has played a critical role in American history during the Westward Migration, the American Civil War, and the Industrial Revolution. During part of the 19th century, the building of the Pennsylvania Canal and later the Pennsylvania Railroad, allowed Harrisburg to became one of the most industrialized cities in the northeastern United States.
Contrasting its 1981 status as the second most distressed city in the nation, Harrisburg has undergone a dramatic economic resurgence since, with nearly $3 billion in new investment now realized. The US Navy ship USS Harrisburg, which served from 1918-19 at the end of World War I, is named in honor of the city. Harrisburg is also known for the infamous Three Mile Island incident, which occurred in nearby Middletown.
Harrisburg is located at 40°16'11" North, 76°52'32" West (40.269789, -76.875613).
According to the United States Census Bureau, the city has a total area of 29.6 km2 (11.4 mi2). 21.0 km2 (8.1 mi2) of it is land and 8.6 km2 (3.3 mi2) of it is water. The total area is 29.11% water.
Harrisburg is located in the Susquehanna Valley, a rich and fertile agricultural region in south-central Pennsylvania. The region is also situated at the extreme western fringe of the BosWash megalopolis, the name for a group of metropolitan areas in the northeastern United States. Directly to the north of Harrisburg lies the Blue Ridge chain of the Appalachian Mountains.
Harrisburg's western boundary is formed by the Susquehanna River, which also serves as the boundary between Dauphin and Cumberland counties. The city is divided into numerous neighborhoods and districts. There are several communities that exist outside the Harrisburg city limits that, although autonomous, still share the designated name Harrisburg.

Since the 1950's, Harrisburg along with other urban centers large and small, has experienced a declining population that is ultimately fueling the growth of it's suburbs. Unlike other states, Pennsylvania maintains a complex system of municipalities and has very little legislation on either the annexation/expansion of cities or the consolidating of municipal entities.
In 1719, John Harris, Sr., an English trader, settled here and 14 years later secured grants of 800 acres (3.2 km2) in this vicinity. In 1753 his son, John Harris, Jr. established a ferry, and the place was long known as Harris's Ferry. In 1785, a town was laid out and named Harrisburg, but in the following year it was renamed Louisburg in honor of Louis XVI. In 1791, it was incorporated as Harrisburg, and was named the Pennsylvania state capital in 1812. In 1860, it was chartered as a city.
The assembling here of the Harrisburg Convention in 1827 led to the passage of the high protective-tariff bill of 1828. In 1839, Harrison and Tyler were nominated at Harrisburg.
