[3] By 1700 the Haudenosaunee, the Five Nations-based south of the Great Lakes in present-day New York, held dominion over the upper Ohio valley, reserving it for hunting grounds.
[5] In 1748, when Conrad Weiser visited Logstown, 18 miles (29 km) downriver from Pittsburgh, he counted 789 warriors gathered: the Iroquois included 163 Seneca, 74 Mohawk, 35 Onondaga, 20 Cayuga, and 15 Oneida.
From a post at present-day Cumberland, Maryland, the company began to construct an 80-mile (130 km) wagon road to the Monongahela River[11] employing a Lenape Indian chief named Nemacolin and a party of settlers headed by Capt.
[18] After the battle, Washington's ally, Seneca chief Tanaghrisson, unexpectedly executed the French commanding officer, Ensign Joseph Coulon de Jumonville.
[15] On September 8, 1756, an expedition of 300 militiamen destroyed the Shawnee and Lenape village of Kittanning, and in the summer of 1758, British Army officer John Forbes began a campaign to capture Fort Duquesne.
[21][22]: 148 After Britain's victory in the French and Indian War, increasing dissatisfaction among Native Americans with the continuing encroachment of settlers on lands that had been agreed would be Indian-occupied (both in the 1758 Treaty of Easton and in the Royal Proclamation of 1763 the British authorities had decreed that there would be no British-American settlements west of the Alleghenies, but the authorities had been unable or unwilling to enforce these decrees) led to the outbreak of Pontiac's War.
The life of a settler family was one of relentless hard work: clearing the forest, stumping the fields, building cabins and barns, planting, weeding, and harvesting.
[4] With the war still ongoing, in 1780 Virginia and Pennsylvania came to an agreement on their mutual borders, creating the state lines known today and determining finally that the jurisdiction of Pittsburgh region was Pennsylvanian.
Pittsburgh was located in the middle of one of the most productive coalfields in the country; the region was also rich in petroleum, natural gas, lumber, and farm goods.
The American Civil War boosted the city's economy with increased production of iron and armaments, especially at the Allegheny Arsenal and the Fort Pitt Foundry.
[40][41] Banks played a key role in Pittsburgh's development as these industrialists sought massive loans to upgrade plants, integrate industries and fund technological advances.
[42] Beginning in the 1870s, entrepreneurs transformed the economy from small, craft-organized factories located inside the city limits to a large integrated industrial region stretching 50 miles across Allegheny County.
The rapid growth of steel, glass, railroad equipment, and coke industries resulted in both large mass-production plants and numerous smaller firms.
As capital deepened and interdependence grew, participants multiplied, economies accrued, the division of labor increased, and localized production systems formed around these industries.
Caught up in a dramatic round of industrial restructuring and labor tension, Pittsburgh steelmaker George McMurtry hired Frederick Law Olmsted's landscape architectural firm in 1895 to design Vandergrift as a model town.
The Olmsted firm translated this agenda into an urban design that included a unique combination of social reform, comprehensive infrastructure planning, and private homeownership principles.
Heinz was at the forefront of reform efforts to improve food purity, working conditions, hours, and wages,[48] but the company bitterly opposed the formation of an independent labor union.
[52][53] Several factors fed into resistance to Prohibition, including a large immigrant population, anti-establishment animosity dating to the Whiskey Rebellion, fragmented local government, and pervasive corruption.
[60] Oakland became the city's predominant cultural and educational center, including three universities, multiple museums, a library, a music hall, and a botanical conservatory.
The increased production output created a workforce shortage, which resulted in African Americans moving en masse during the Second Great Migration from the South to the city in order to find work.
Rich and productive, Pittsburgh was also the "Smoky City", with smog sometimes so thick that streetlights burned during the day[11] as well as rivers that resembled open sewers.
Ninety-five acres of the lower Hill District were cleared using eminent domain, forcibly displacing hundreds of small businesses and more than 8,000 people (1,239 black families, 312 white), to make room for a cultural center that included the Civic Arena, which opened in 1961.
All of the buildings, with the exception of the Old U.S. Post Office, the Carnegie Library, and Buhl Planetarium were destroyed and replaced with the "pedestrianized" Allegheny Center Mall and apartments.
The collapse of steel put pressure on those two universities to reinvent themselves as research centers in science and technology which acted to pull the regional economy toward high-technology fields.
Beginning in the 1980s, Pittsburgh's economy shifted from heavy industry to services, medicine, higher education, tourism, banking, corporate headquarters, and high technology.
Aided by an initial generous gift from the Allegheny Foundation in 1976, Landmarks adapted five historic Pittsburgh and Lake Erie Railroad buildings for new uses and added a hotel, a dock for the Gateway Clipper fleet, and parking areas.
Now shops, offices, restaurants, and entertainment anchor the historic riverfront site on the south shore of the Monongahela River, opposite the Golden Triangle (Pittsburgh).
It reflects a $100 million investment from all sources, with the lowest public cost and highest taxpayer return of any major renewal project in the Pittsburgh region since the 1950s.
In 1994, Pittsburgh History and Landmarks Foundation sold Station Square in to Forest City Enterprises which created an endowment to help support its restoration efforts and educational programs.
[94] Present-day Pittsburgh, with a diversified economy, a low cost of living, and a rich infrastructure for medicine and education and culture, has been ranked as one of the World's Most Livable Cities.
As I got down before the Canoe, I spent some Time in viewing the Rivers, & the Land in the Fork, which I think extremely well situated for a Fort; as it has the absolute Command of both Rivers. The Land at the Point is 20 or 25 feet (7.6 m) above the common Surface of the Water; & a considerable Bottom of flat well timber'd Land all around it, very convenient for Building.
