The record high minimum is 83 °F (28 °C) on July 23, 2011, and July 24, 2010. See or edit raw graph data . Philadelphia County received an ozone grade of F and
7632-594: The late 1970s and continues into the 21st century with much of the development occurring in the Center City and University City neighborhoods. But this expanded a shortage of affordable housing in the city. After many manufacturers and businesses left Philadelphia or shut down, the city started attracting service businesses and began to market itself more aggressively as a tourist destination. Contemporary glass-and-granite skyscrapers were built in Center City beginning in
7738-927: The nation, including a fire company , library , and hospital . A number of philosophical societies were formed, which were centers of the city's intellectual life, including the Philadelphia Society for Promoting Agriculture (1785), the Pennsylvania Society for the Encouragement of Manufactures and the Useful Arts (1787), the Academy of Natural Sciences (1812), and the Franklin Institute (1824). These societies developed and financed new industries that attracted skilled and knowledgeable immigrants from Europe. Philadelphia's importance and central location in
7844-619: The nearest British outposts. In part as a retaliatory measure against the ongoing skirmishes, General Charles Cornwallis executed a raid against that position in April 1777, in which he very nearly captured the outpost's commander, Benjamin Lincoln . In response to this raid, Washington moved his army forward to a strongly fortified position at Middlebrook in the Watchung Mountains that commanded likely British land routes toward Philadelphia. For reasons that are not entirely clear, Howe moved
7950-449: The northwest; Bucks to the north and northeast; Burlington County, New Jersey to the east; Camden County, New Jersey to the southeast; Gloucester County, New Jersey to the south; and Delaware County to the southwest. Philadelphia was created in the 17th century, following the plan by William Penn 's surveyor Thomas Holme . Center City is structured with long, straight streets running nearly due east–west and north–south, forming
8056-433: The railroad got out of the shipping business soon afterward. Its first president was Herman Joseph Lombaert (1816–1885), a PRR vice-president who resigned from the railroad when the shipping company became independent. The company's most prominent president was Clement Griscom , who led the company from 1888 to 1902 and worked as a company executive for its entire existence. The company became much larger when it bought out
8162-590: The rebel capital did not bring the end to the rebellion as the British thought it would. In 18th-century warfare, it was normal that the side who captured the opposing force's capital city won the war, but the Revolutionary War would continue for six more years until 1783 because of the rebels' unconventional warfare tactics. After capturing Philadelphia, the British garrisoned about 9,000 troops in Germantown , 5 miles (8 km) north of Philadelphia. On October 2,
8268-609: The same strategic positions that they had been in before Howe launched the attack on Philadelphia. Following William Howe 's capture of New York City and George Washington 's success in the Battles of Trenton and Princeton , the two armies settled into an uneasy stalemate in the winter months of early 1777. While punctuated by numerous skirmishes , the British Army continued to occupy outposts at New Brunswick and Perth Amboy in New Jersey . In 1777, Howe proposed to George Germain ,
8374-745: The second half of the 19th century. His contemporaries included John McArthur Jr. , Addison Hutton , Wilson Eyre , the Wilson Brothers , and Horace Trumbauer . In 1871, construction began on the Second Empire -style Philadelphia City Hall .

The commission maintains the Philadelphia Register of Historic Places , adding historic buildings, structures, sites, objects and districts as it sees fit. In 1932, Philadelphia became home to
8480-592: The situation did not change substantially until 1682, when the area was included in William Penn 's charter for Pennsylvania. In 1681, in partial repayment of a debt, Charles II of England granted Penn a charter for what would become the Pennsylvania colony . Despite the royal charter, Penn bought the land from the local Lenape in an effort to establish good terms with the Native Americans and ensure peace for
8586-467: The spine of the north–south highway system along the U.S. East Coast . Philadelphia is a city of many firsts, including the nation's first library (1731), hospital (1751), medical school (1765), national capital (1774), university (by some accounts) (1779), central bank (1781), stock exchange (1790), zoo (1874), and business school (1881). Philadelphia contains 67 National Historic Landmarks , including Independence Hall . From
8692-493: The surrounding Delaware Valley in the early 17th century. The first settlements were founded by Dutch colonists , who built Fort Nassau on the Delaware River in 1623 in what is now Brooklawn, New Jersey . The Dutch considered the entire Delaware River valley to be part of their New Netherland colony. In 1638, Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina , located in present-day Wilmington, Delaware , and quickly spread out in
8798-522: The ten largest combined statistical areas (CSAs) were ranked higher for ozone: Los Angeles (1st), New York City (9th), Houston (12th), Dallas (13th), and San Jose, California (18th). Many smaller CSAs were also ranked higher for ozone, including Sacramento (8th), Las Vegas (10th), Denver (11th), El Paso (16th), and Salt Lake City (20th). Only two of those same ten CSAs, San Jose and Los Angeles, were ranked higher than Philadelphia for both year-round and short-term particle pollution. As of
8904-586: The transportation or construction of necessary watercraft. Howe's plan, sent to Germain on April 2, isolated Burgoyne from any possibility of significant support, since Howe instead would take the British Army to Philadelphia by sea, and the New York garrison would be too small for any significant offensive operations up the Hudson River to assist Burgoyne. Washington realized that Howe "certainly ought in good policy to endeavor to Cooperate with Genl. Burgoyne " and
9010-606: The upper Ohio River basin. Following the American Revolutionary War and subsequent formation of an independent United States, the Lenape began moving further west. In the 1860s, the United States government sent most remaining Lenape in the eastern United States to the Indian Territory in present-day Oklahoma and surrounding territories as part of the Indian removal policy. Europeans first entered Philadelphia and
9116-516: The valley. In 1644, New Sweden supported the Susquehannocks in their war against Maryland colonists. In 1648, the Dutch built Fort Beversreede on the west bank of the Delaware, south of the Schuylkill River near the present-day Eastwick section of Philadelphia, to reassert their dominion over the area. The Swedes responded by building Fort Nya Korsholm , or New Korsholm , named after
9222-461: The war. In the Philadelphia campaign, British General William Howe failed to draw the Continental Army under George Washington into a battle in North Jersey . Howe then embarked his army on transports, and landed them at the northern end of the Chesapeake Bay , where they began advancing north toward Philadelphia. Washington prepared defenses against Howe's movements at Brandywine Creek , but
9328-470: The whole matter openly before Continental Congress. In response, his supporters rallied behind him, and Washington's leadership was reassured. Washington and his army encamped at Valley Forge in December 1777, about 20 miles (32 km) from Philadelphia , where they stayed for the next six months. Over the winter, 2,500 men (out of 10,000) died from disease and exposure. However, the army eventually emerged from Valley Forge in good order, thanks in part to
9434-491: The year. The average window for freezing temperatures is November 6 to April 2, allowing a growing season of 217 days. Early fall and late winter are generally dry, with February having the lowest average precipitation at 2.75 inches (70 mm). The dewpoint in the summer averages between 59.1 and 64.5 °F (15 and 18 °C). The highest recorded temperature was 106 °F (41 °C) on August 7, 1918. Temperatures at or above 100 °F (38 °C) are not common, with
9540-457: Was "persuaded the Principal Army should act offensively [against Philadelphia], where the enemy's chief strength lies." Germain acknowledged that this plan was particularly "well digested", but it called for more men than Germain was prepared to provide. After the setbacks in New Jersey, Howe in mid-January 1777 proposed operations against Philadelphia that included an overland expedition and
9646-536: Was 30.7 in (78 cm), which occurred in January 1996. Precipitation is generally spread throughout the year, with eight to eleven wet days per month, at an average annual rate of 44.1 inches (1,120 mm), but historically ranging from 29.31 in (744 mm) in 1922 to 64.33 in (1,634 mm) in 2011. The most rain recorded in one day occurred on July 28, 2013, when 8.02 in (204 mm) fell at Philadelphia International Airport . Philadelphia has

9858-511: Was baffled why he did not do so. Washington at the time and historians ever since have wondered why Howe was not in place to come to the relief of Burgoyne, whose invasion army from Canada was surrounded and captured by the Americans in October. Historians agree that Lord Germain did a poor job in coordinating the two campaigns. Following Howe's capture of New York City and Washington's retreat across
9964-466: Was being constructed and prepared to serve as the new national capital. In 1793, the largest yellow fever epidemic in U.S. history killed approximately 4,000 to 5,000 people in Philadelphia, or about ten percent of the city's population at the time. The capital of the United States was moved to Washington, D.C. in 1800 upon completion of the White House and U.S. Capitol buildings. The state capital
10070-492: Was controversial because, while he succeeded in capturing the revolutionary capital of Philadelphia, he proceeded slowly and did not aid the concurrent campaign of John Burgoyne further north, which ended in disaster for the British in the Battles of Saratoga and brought France into the war. Howe resigned during the occupation of Philadelphia and was replaced by his second-in-command, General Sir Henry Clinton . In 1778, Clinton
10176-506: Was developed south of South Street and later occupied by succeeding immigrants. They established a network of Catholic churches and schools and dominated the Catholic clergy for decades.

In the first decades of the 19th century, Federal and Greek Revival architecture were the dominant styles produced by Philadelphia architects such as Benjamin Latrobe , William Strickland , John Haviland , John Notman , Thomas Walter , and Samuel Sloan . Frank Furness is considered Philadelphia's greatest architect of
10388-414: Was flanked and beaten back in the Battle of Brandywine on September 11, 1777. After further skirmishes and maneuvers, Howe entered and occupied Philadelphia. Washington then unsuccessfully attacked one of Howe's garrisons at Germantown prior to retreating to Valley Forge for the winter, where he and 12,000 faced the harshest winter of the war, including insufficient food and clothing. Howe's campaign
10494-604: Was founded in 1682 by William Penn , an English Quaker and advocate of religious freedom , and served as the capital of the Pennsylvania Colony during the British colonial era . The city went on to play a historic and vital role during the American Revolution and Revolutionary War , serving as the central meeting place for the nation's founding fathers , hosting the First Continental Congress in 1774, preserving
10600-486: Was going. Considering the possibility that Howe was again feinting, and would actually sail his army up the Hudson to join with Burgoyne, he remained near New York. Only when he received word that Howe's fleet had reached the mouth of the Delaware, did he need to consider the defense of Philadelphia. However, the fleet did not enter the Delaware, instead continuing south. Uncertain of Howe's goal, which could be Charleston, South Carolina , he considered moving north to assist in
10706-515: Was moved from Philadelphia to Lancaster in 1799, then ultimately to Harrisburg in 1812. Philadelphia remained the nation's largest city until the late 18th century. It also was the nation's financial and cultural center until ultimately being eclipsed in total population by New York City in 1790. In 1816, the city's free Black community founded the African Methodist Episcopal Church , the first independent Black denomination in
10812-500: Was of him and that he was not eager to do anything which might assist his junior up the ladder of military renown." Along the same lines Don Higginbotham concludes that in Howe's view, "[The Hudson River campaign] was Burgoyne's whole show, and consequently he [Howe] wanted little to do with it. With regard to Burgoyne's army, he would do only what was required of him (virtually nothing)." Howe himself wrote to Burgoyne on July 17: "My intention
10918-498: Was once again forced to abandon the city, relocating first to Lancaster, Pennsylvania , and later York, Pennsylvania . British and Revolutionary forces maneuvered around each other west of Philadelphia for the next several days, clashing in minor encounters such as the abortive Battle of the Clouds and the so-called " Paoli Massacre ." On September 26, Howe finally outmaneuvered Washington and marched into Philadelphia unopposed. Capture of
11024-406: Was one of more than 36 industrial cities nationally to suffer a race riot during Red Summer in post- World War I unrest as recent immigrants competed with Blacks for jobs. In the 1920s, the public flouting of Prohibition laws, organized crime , mob violence, and corrupt police involvement in illegal activities led to the appointment of Brig. Gen. Smedley Butler of the U.S. Marine Corps as
11130-439: Was ordered to evacuate Philadelphia and consolidate his troops in New York City , in anticipation of a combined Franco-American attack there. Many Loyalists also left Philadelphia, fearing persecution. Washington's forces shadowed the withdrawing British Army until they clashed at the Battle of Monmouth , one of the war's largest battles. At the end of the Philadelphia campaign in 1778, the two armies found themselves in roughly
