Harrisburg ( HARR-iss-burg; Pennsylvania German: Harrisbarrig) is the capital city of the U.S. commonwealth of Pennsylvania. It is the ninth-most populous city in the state, with a population of 50,099 at the 2020 census, while the Harrisburg–Carlisle metropolitan statistical area has an estimated 615,000 residents and is the fourth-most populous metropolitan area in Pennsylvania. Harrisburg is situated on the east bank of the Susquehanna River 83 miles (134 km) southwest of Allentown and 108 miles (174 km) northwest of Philadelphia. It is officially incorporated as a third-class city and is the county seat of Dauphin County.
Harrisburg played a 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 develop into one of the most industrialized cities in the Northeastern United States. In the mid- to late 20th century, the city's economic fortunes fluctuated with its major industries consisting of government, heavy manufacturing, agriculture, and food services. These economic fluctuations contributed to Harrisburg experiencing a decline of nearly half its population between 1950 and 2000. However, the region is seen as financially stable in part due to the high concentration of state and federal government agencies.
The Pennsylvania Farm Show, the largest indoor agriculture exposition in the U.S., was first held in Harrisburg in 1917 and has been held there annually in early to mid–January since. The city also hosts the annual Great American Outdoor Show, the largest of its kind in the world, among many other events. Harrisburg experienced the Three Mile Island accident on March 28, 1979, in nearby Middletown.
History
Founding
Harrisburg's site along the Susquehanna River is thought to have been inhabited by Native Americans as early as 3000 BC. Known to the Native Americans as "Peixtin", or "Paxtang", the area was an important resting place and crossroads for Native American traders with trails leading from the Delaware to the Ohio rivers and from the Potomac to the Upper Susquehanna intersecting there.
17th century
The first European contact with Native Americans in Pennsylvania was made by Englishman Captain John Smith, who journeyed from Virginia up the Susquehanna River in 1608 and visited with the Susquehanna tribe.
18th century
In 1719, John Harris, Sr., an English trader, settled here; 14 years later, he secured grants of 800 acres (3.2 km2) in this vicinity. In 1785, John Harris, Jr. made plans to lay out a town on his father's land, which he named Harrisburg. In the spring of 1785, the town was formally surveyed by William Maclay, who was a son-in-law of John Harris, Sr. In 1791, Harrisburg became incorporated.
19th century
In October 1812 Harrisburg was named the Pennsylvania state capital, which it has remained ever since. The assembling here of the highly sectional Harrisburg Convention in 1827 (signaling what may have been the birth of lobbying on a national scale) led to the passage of the high protective-tariff bill of 1828.
In 1839, William Henry Harrison and John Tyler were nominated for president and Vice President of the United States at the first national convention of the Whig Party of the United States, which was held in Harrisburg.
Before Harrisburg gained its first industries, it was a scenic, pastoral town: compact and surrounded by farmland. In 1822, the impressive brick capitol was completed for $200,000 (~$6.1 million in 2025).
Harrisburg's strategic location gave it an advantage over many other towns; it was settled as a trading post in 1719 at a location important to westward expansion, past the Blue Mountain range. The Susquehanna River flowed generally west to east at this location, providing a route for boat traffic from the east. The head of navigation was a short distance northwest of the town, where the river flowed through the pass. Persons arriving from the east by boat had to exit at Harrisburg and prepare for an overland journey westward through the mountain pass. Harrisburg assumed importance as a provisioning stop at this point where westward bound pioneers transitioned from river travel to overland travel. It was partly because of its strategic location that the state legislature selected the small town of Harrisburg to become the state capital in 1812.
The grandeur of the Colonial Revival capitol dominated the quaint town. The streets were dirt, but orderly and platted in grid pattern. The Pennsylvania Canal was built in 1834 and coursed the length of the town. The residential houses were situated on only a few city blocks stretching southward from the capitol. They were mostly one story. No factories were present but there were blacksmith shops and other businesses. The ownership of land concentrated in the hands of a small number of wealthy families: five people held one-third of private land in 1850.
During the first part of the 19th century, Harrisburg was a notable stopping place along the Underground Railroad, as persons escaping slavery used the Susquehanna River to access food and supplies before heading north towards Canada.
During the American Civil War, Harrisburg became a significant training center for the Union army, with tens of thousands of troops passing through Camp Curtin, which was established on April 18, 1861 and named in honor of Pennsylvania's Civil War-era governor, Andrew Gregg Curtin.
Harrisburg functioned as a major rail center for the Union and a vital link between the Atlantic coast and the Midwest, with several railroads running through the city and spanning the Susquehanna River. As a result of this importance, the city was targeted by General Robert E. Lee's Army of Northern Virginia during the army's two invasions. First, during the 1862 Maryland Campaign, when Lee planned to capture the city after taking Harpers Ferry, West Virginia, but was prevented from doing so by the Battle of Antietam and his subsequent retreat back into Virginia. The second attempt was made during the Gettysburg campaign in 1863 and was more substantial. Under orders from Gen. Robert E. Lee directly, Confederate Lt. Gen. Richard S. Ewell's Second Corps were tasked with capturing Harrisburg and disrupting the vital Union supply and rail lines. However, Ewell's forces were intercepted by the forces of the Department of the Susquehanna under the command of Union Maj. Gen. Darius N. Couch in a series of skirmishes surrounding the city, such as the Skirmish of Sporting Hill in Camp Hill, just 2 miles (3 km) west of Harrisburg. The Second Corp were ultimately unsuccessful in both overcoming the local Union defenses and crossing the rain bloated Susquehanna into Harrisburg itself, and were forced to retreat southward to regroup with Lee's main Confederate force. This attempt marked the northernmost advance of the Confederate Army during the Civil War.
On July 3, 1863, the artillery barrage that marked the beginning of Pickett's Charge of the Battle of Gettysburg was heard from Harrisburg, almost 40 miles away.
Harrisburg's importance in the latter half of the 19th century was in the steel industry. It was an important railroad center as well. Steel and iron became dominant industries. Steel and other industries continued to play a major role in the local economy throughout the latter part of the 19th century. The city was the center of enormous railroad traffic and its steel industry supported large furnaces, rolling mills, and machine shops. The Pennsylvania Steel Company plant, which opened in nearby Steelton in 1866, was the first in the country; later operated by Bethlehem Steel.
Its first large scale iron foundries were put into operation shortly after 1850.
As industries nationwide entered a phase of great expansion and technological improvement, so did industries – and in particular the steel industry – in Harrisburg. This can be attributed to a combination of factors that were typical of what existed in other successful industrial cities: rapid rail expansion; nearby markets for goods; and nearby sources for raw product.
With Harrisburg poised for growth in steel production, Steelton became the ideal location for this type of industry. It was a wide swath of flat land located south of the city, with rail and canal access running its entire 4 mile length. There was plenty of room for houses and its own downtown section. Steelton was a company town, opened in 1866 by the Pennsylvania Steel Company. Highly innovative in its steel making process, it became the first mill in the United States to make steel railroad rails by contract. In its prime, Steelton was home to more than 16,000 residents from 33 different ethnic groups. All were employed in the steel industry, or had employment in services that supported it. In the late 19th century, no less than five major steel mills and foundries were located in Steelton. Each contained a maze of buildings; conveyances for moving the products; large yards for laying down equipment; and facilities for loading their product on trains. Stacks from these factories constantly belched smoke. With housing and a small downtown area within walking distance, these were the sights and smells that most Steelton residents saw every day.
The rail yard was another area of Harrisburg that saw rapid and thorough change during the years of industrialization. This was a wide expanse of about two dozen railroad tracks that grew from the single track of the early 1850s. By the late 19th century, this area was the width of about two city blocks and formed what amounted to a barrier along the eastern edge of the city: passable only by bridge. Three large and ornately embellished passenger depots were built by as many rail lines. Pennsylvania Railroad was the largest rail line in Harrisburg. It built huge repair facilities and two large roundhouses in the 1860s and 1870s to handle its enormous freight and passenger traffic and to maintain its colossal infrastructure. Its rails ran the length of Harrisburg, along its eastern border. It had a succession of three passenger depots, each built on the site of the predecessor, and each of high style architecture, including a train shed to protect passengers from inclement weather. At its peak in 1904, it made 100 passenger stops per day. It extended west to Pittsburgh, across the entire state, and east to Philadelphia, serving Steelton along the route. The anthracite coal mines in the Allegheny Mountains were reached by the Northern Central Railroad. The Lebanon Valley Railroad extended east to Philadelphia with spurs to New York City. Another rail line was the Philadelphia and Reading Railroad, which provided service to Philadelphia and other points east.
Allison Hill, Harrisburg's first suburb, is located east of the city on a prominent bluff, accessed by bridges across a wide swath of train tracks. It was developed in the late 19th century and offered affluent Harrisburg residents the opportunity to live in the suburbs only a few hundred yards from their jobs in the city. As the city expanded, it incorporated Allison Hill in its boundaries. In 1886, a single horse trolley line was established from the city to Allison Hill. Easy access was later achieved via the State Street Bridge leading east from the Capitol complex and the Market Street Bridge leading from the city's prominent business district. Among the most desirable sections of Allison Hill at the time was Mount Pleasant, which was characterized by large Colonial Revival-style houses with yards for the very wealthy and smaller but still well-built row houses lining the main street for the moderately wealthy. State Street, leading from the Capitol directly toward Allison Hill, was planned to provide a grand view of the Capitol dome for those approaching the city from Allison Hill. This trend towards outlying residential areas began slowly in the late 19th century and was largely confined to the trolley line, but the growing prevalence of automobile ownership quickened the trend and spread out the population in the 20th century.
20th century
In the early 20th century, the city of Harrisburg was in need of change. Without proper sanitation, diseases such as typhoid began killing many citizens of Harrisburg. Seeing these necessary changes, several Harrisburg residents became involved in the City Beautiful movement. The project focused on providing better transportation, spaces for recreation, sanitation, landscaping, and parks for those living in cities, as research showed that a person with access to amenities would be a happier person. In December 1900, a reformer named Mira Lloyd Dock, who had recently encountered well-ordered urban centers on an international trip to Europe, gave a lecture on "The City Beautiful" to Harrisburg's Board of Trade. Other prominent citizens of the city such as J. Horace McFarland and Vance McCormick advocated urban improvements which were influenced by European urban planning design and the World's Columbian Exposition. Warren Manning was hired to help bring about these changes. Specifically, their efforts greatly enlarged the Harrisburg park system, creating Riverfront Park, Reservoir Park, the Italian Lake and Wildwood Park. In addition, plans were undertaken for new water filtration, burial of electric wires, the paving of roads, and the creation of a modern sanitary sewer system. The efforts to improve the city also paralleled the construction of an expanded monumental Capitol complex in 1906 which led, in turn, to the displacement of the Old Eighth Ward, one of the most ethnically and racially diverse communities in Harrisburg.
