18th century In the early 18th century, the area that is present-day Allentown was a wilderness of
scrub oak, where the
Lenape, an
Indigenous tribe, fished for trout and hunted for deer, grouse, and other game. On May 18, 1732, the land was deeded by
Thomas Penn, one of three sons of
William Penn, founder of the
colonial era Province of Pennsylvania, to
Joseph Turner, a
Philadelphia-based
iron manufacturer and politician. Two years later, on September 10, 1735, a portion of this land was purchased from Turner's business partner by
William Allen, a wealthy shipping merchant who became
mayor of Philadelphia the following month. In 1737, as part of the
Walking Purchase, a large area north of Philadelphia, including present-day Allentown, was deeded by 23 chiefs of the
Five Civilized Tribes to three sons of William Penn,
John, Thomas, and
Richard, in exchange for shoes, buckles, hats, shirts, knives, scissors, combs, needles,
looking glasses, rum, and pipes. The land was surveyed in 1736 and again in 1753 as part of an effort to construct a road from
Easton to the city's east to
Reading to its west. In 1752,
Northampton and
Berks counties were formed; Easton was named the
county seat of Northampton County, and Reading the county seat of Berks County. In 1762, the land, including present-day Allentown, was named and laid out by Allen, and the city was founded. A rivalry between the Penns and Allen may have inspired Allen to acquire the land and found the city. In 1767, Allen granted the land to his son James.
American Revolutionary War at 739
Hamilton Street, where a hospital treated wounded
Continental Army troops during the
Revolutionary War Allentown played a central role in inspiring and supporting the
American Revolution and
Revolutionary War. Some of the first
Patriot resistance to
British colonialism in the
Thirteen Colonies began in and around present-day Allentown. On December 21, 1774, a
Committee of Observation was formed by Allentown-area patriots, who expanded their resistance to British governance, and drove
Tories out of the city. The burden of supplying the local militias fell on the people, and requisitions for food, grain, cattle, horses, and cloth were common. In June 1775, after the Revolutionary War was launched with the
Battles of Lexington and Concord, the
Second Continental Congress incorporated Patriot militias, including those in present-day Allentown, into the
Continental Army and unanimously selected
George Washington as its commander. During the Revolutionary War,
Hessian prisoners of war were kept in Allentown in the vicinity of present-day 7th and Gordon streets, and the city housed four hospitals for wounded Continental Army troops, including one in
Zion Reformed Church and one on the grounds of the present-day
Farr Building. After
crossing the Delaware and prevailing in the
Battle of Trenton on December 26, 1776, Continental Army commander George Washington and his staff traveled through Allentown, where they proceeded up Water Street, which is present-day
Lehigh Street. On the grounds of present-day Wire Mill on Lehigh Street, Washington and his staff stopped at the foot of the street, where they rested and watered their horses, and then proceeded to their post of duty. In 1777, a manufacturer of
paper cartridges and
muskets for the Continental Army relocated to Allentown from neighboring
Bethlehem, and a shop of 16
armourers was established on
Little Lehigh Creek, which was used to repair Continental Army weapons and manufacture
saddles and
scabbards. Allentown holds historical significance as the location where the
Liberty Bell, then known as the State House Bell, was successfully hidden from September 1777 to June 1778, during the Revolutionary War by
American patriots, who sought to avoid its capture by the
British Army during their nine-month
occupation of Philadelphia. After Washington and the Continental Army were defeated in the
Battle of Brandywine in
Chadds Ford Township, Pennsylvania on September 11, 1777, Philadelphia was left defenseless and American patriots began preparing for what they saw as an imminent British attack on the colonial capital.
Pennsylvania's Supreme Executive Council ordered that 11 bells, including the Liberty Bell and ten bells then housed at
Christ Church and
St. Peter's Church in Philadelphia, be taken down and moved out of Philadelphia to protect them from the British, fearing their being melted down and cast into munitions. Two farmers and wagon masters, John Snyder and Henry Bartholomew, then transported the Liberty Bell north to present-day Allentown, where it was hidden under floorboards in the basement of
Zion Reformed Church at 622
Hamilton Street in
Center City Allentown, just prior to Philadelphia's September 1777 fall to the British.
19th century In 1803, the city, whose mail was previously received in neighboring
Bethlehem, had a post office established inside Compass and Square Hotel inside the present-day Penn National Bank building at 645
Hamilton Street in Allentown. In the
1810 U.S. census, the city's population exceeded 700 residents, and the Commonwealth of Pennsylvania granted the city legal standing on March 18, 1811, incorporating it initially as the Borough of Northampton in what was then
Northampton County. The new borough's first undertaking was ordering that cows be moved from public streets to pastures, which proved unpopular with residents. The following year, in 1812, the city became part of
Lehigh County, which was partitioned from a western section of Northampton County. Throughout the early 1800s, the city grew primarily as a court and market town. Northampton Bank, the city's first bank located at the northeast corner of Center Square, was chartered in July 1814, and the first Hamilton Street Bridge, a -long chain structure, was constructed to cross
Lehigh River in the city. The bridge featured two suspended lanes, one for east and one for westbound traffic, and a toll house at the bridge's western end. In 1829,
Lehigh Canal, a -long canal on Lehigh River's east side, was completed for both ascending and descending navigation, which proved influential in expanding the transport of
anthracite coal, then one of the most important domestic and industrial fuels, from Allentown to
New York City,
Philadelphia, and other major industrial centers. In 1855, the city's first railroad was built on the west side of the Lehigh River, and rail soon began surpassing river transport as the primary means for transporting anthracite through the city. In the meeting, citizens voted to establish and equip the
1st Pennsylvania Volunteer Infantry, a new military unit, and placed Captain Samuel Yohe of Easton and Thomas W. Lynn in charge of it, awarding them the respective ranks of colonel and major. Tilghman H. Good of
South Whitehall Township, previously captain of Allen Rifles, an Allentown-based militia, and commander of the
4th Pennsylvania Infantry Regiment, was placed in charge of the 1st Pennsylvania's Company I, which included his former Allen Rifles subordinates and members of Jordan Artillerist, another Allentown-based militia. In April 1861, following the Confederate
bombardment of Fort Sumter, these Allentown units were deployed in response to
President Lincoln's call for 75,000 volunteers to defend the national capital of
Washington, D.C. from Confederate attack. After protecting the nation's capital from April to July 1861, these volunteers were honorably discharged and returned home, though a significant number reenlisted to defend the Union as the Civil War escalated. After the Civil War's end, many of these soldiers were named
Pennsylvania First Defenders in recognition of their role as one of the first five units to answer Lincoln's call for volunteers to defend the nation's capital.
47th Regiment Pennsylvania Volunteer Infantry On August 5, 1861,
Andrew Gregg Curtin, the Civil War-era
Pennsylvania governor, granted Tilghman H. Good authority to create the
47th Pennsylvania Infantry Regiment, a new unit commonly known as the 47th Pennsylvania Volunteers. Good secured the assistance of William H. Gausler of Allentown, who was commissioned as a major with the regiment's central command staff, and
John Peter Shindel Gobin, a senior officer with Sunbury Guards in
Northumberland County, who was repeatedly cited for valor and was promoted to colonel and ultimately as commanding officer of the regiment. Companies A and E of the regiment were recruited primarily from Easton and Northampton County; Companies B, G, I, and K were largely recruited from Allentown; Company C was recruited from Northumberland and
Juniata counties; Company F was primarily composed of men from the Allentown suburb of
Catasaqua; and Companies D and H were recruited from
Perry County. The 47th Pennsylvania Volunteers achieved Union victories at the
Battle of St. Johns Bluff in Florida (October 1–3, 1862) before suffering a costly defeat in the
Second Battle of Pocotaligo in South Carolina (October 21–23, 1862). They were the only Pennsylvania regiment to fight in the
Union army's
Red River campaign across
Louisiana in 1864. While sustaining numerous casualties during the Red River campaign, the 47th Pennsylvania helped
turn the Civil War in the Union's favor, contributing to influential military victories in
General Sheridan's 1864 Shenandoah Valley campaign across Virginia, including in the Battles of
Berryville,
Opequan,
Fisher's Hill, and
Cedar Creek, and then again contributing to the nation's defense following
Lincoln's assassination on April 15, 1865. Other known Union military units from Allentown included the 5th, 41st,
128th, and 176th Pennsylvania Infantries.
Industrialization s throughout the early 20th century, in 1910 streets in present-day
Center City, in 1910 ' assembly plant in Allentown in 1945; the company was headquartered in Allentown from 1905 until 2008, when it relocated to
Greensboro, North Carolina. In the late 18th century, Allentown began growing slowly as a hub for commerce and industrialization and as a
colonial era population center. Prior to the American Revolution, there were 54 homes and approximately 330 residents. In 1782, there were 59 houses and over 100 cows. In 1783, the town was described by a visitor, "One gets a glimpse of many good stone houses, many of them very neat, and everything about the premises shows good order and attention. The people are mainly
German who speak bad English and distressing
German." In 1795,
Gazette of the United States described Allentown as: A handsome and flourishing town of Northampton County, pleasantly situated on the point of land formed by the junction of the
Jordan Creek and
Little Lehigh. It is regularly laid out and contains about ninety dwellings, a
German Lutheran and a
Calvinist (Zion) Church, an Academy and three merchant mills.
Neuweiler Brewery (founded 1875, closed 1968), and
Schaefer Beer, whose brewery was later acquired by
Pabst and
Guinness and is now owned by
Boston Beer Company, brewer of
Samuel Adams beer.
20th century In 1905, Jack and Gus Mack moved
Mack Trucks, their motor company, from
Brooklyn to Allentown, taking over the foundries of Weaver-Hirsh on S. 10th Street. By 1914, Mack Trucks developed a global reputation for manufacturing sturdy and reliable trucks and vehicles. Many were sent to
Western Front battlefields in France just before the
U.S. entered World War I in April 1917. The
British Army nicknamed
Mack AC's five and seven-ton trucks the "Bulldog", which was later adopted as the company's corporate brand. Throughout the 20th century, Mack Trucks grew substantially, ultimately including eight Allentown-based manufacturing plants. As of 2015, there were an estimated 5,200
Syrian Americans in Allentown and surrounding Lehigh Valley cities and towns. Like several other regions in Pennsylvania,
Pennsylvania German-speaking residents existed in Allentown into the early 20th century.
Pennsylvania Guide, compiled during the
Great Depression by the
Writers' Project of the
Works Progress Administration, described the impact of the
Pennsylvania Dutch on Allentown's linguistic landscape, reporting in 1940 that:{{Blockquote In October 1945, following the end of
World War II,
Western Electric opened a plant on Union Boulevard in Allentown. Six years later, in October 1951, the company manufactured and released the world's first
transistor, produced at the Allentown-based plant, and the Allentown-based company emerged as a leader in the nation's
post-war electronics revolution. By the mid-20th century, Allentown was a major retailing and entertainment center distinct and separate from
Philadelphia and
New York City. Hess's, Leh's, and Zollinger department stores led to retail sector growth in the city, and dozens of smaller retail stores, restaurants, hotels, banks, and professional offices emerged in present-day
Center City, which was then referred to as downtown Allentown. At least seven cinemas and stage theaters were developed on Hamilton Street between 5th and 10th streets. In 1993, Corporate Center, the city's new flagship business center on N. 7th Street, fell victim to a large
sinkhole, leading to its condemnation and ultimate demolition. Combined with challenges confronting Center City, Allentown also was heavily impacted by a significant downturn in manufacturing throughout the
U.S. Northeast, which began undergoing and suffering from
deindustrialization, a product of foreign competition, trade policies, and relatively higher U.S.-based manufacturing costs. Many Allentown factories and corporations began closing or relocating.
21st century Responding to the late 20th century economic downturn in the city, Allentown began seeking to diversify its economy in the early 21st century.
Allentown's economy saw growth in its service, health care, transportation, warehousing, and some manufacturing industries. In 2009, the
Neighborhood Improvement Zone (NIZ), created by the
Pennsylvania General Assembly, sought to address Allentown's economic challenges and encourage the city's development and revitalization. The NIZ includes approximately in Center City and the city's riverfront district on the west side of the
Lehigh River. In 2006,
Agere Systems, formerly
Western Electric, was acquired by
LSI Corporation, and the company relocated to
San Jose, California. Three years later, in 2009,
Mack Trucks relocated to
Greensboro, North Carolina, and many Allentown-based factories downsized considerably or ceased operations entirely. In 2014, Center City underwent major restructuring, including constructing and opening
PPL Center, a 10,500-capacity indoor arena, which hosts the
Lehigh Valley Phantoms, a professional
American Hockey League ice hockey team, and other sports, entertainment, and concert events. A full-service
Renaissance Hotel also opened in Center City, and older office buildings were redeveloped. In 2024,
U.S. News & World Report ranked Allentown as one of the "150 Best Places to Live in the U.S." and the nation's fifth-best city to retire. ==Geography==
