The area was first inhabited by members of the Nipmuc tribe. The native people called the region Quinsigamond and built a settlement on Pakachoag Hill in Auburn. In 1673 English settlers John Eliot and Daniel Gookin led an expedition to Quinsigamond to establish a new Christian Indian “praying town” and identify a new location for an English settlement. On July 13, 1674, Gookin obtained a deed to eight square miles of land in Quinsigamond from the Nipmuc people and English traders and settlers began to inhabit the region.

In 1675, King Philip’s War broke out throughout New England with the Nipmuc Indians coming to the aid of Indian leader King Philip. The English settlers completely abandoned the Quinsigamond area and the empty buildings were burned by the Indian forces. The town was again abandoned during Queen Anne’s War in 1702. Finally in 1713, Worcester was permanently resettled for a third and final time by Jonas Rice. Named after the city of Worcester, England, the town was incorporated on June 14, 1722. On April 2, 1731, Worcester was chosen as the county seat of the newly founded Worcester County government. Between 1755 and 1758, future U.S. president John Adams worked as a schoolteacher and studied law in Worcester.

In the 1770s, Worcester became a center of American revolutionary activity. British General Thomas Gage was given information of patriot ammunition stockpiled in Worcester in 1775. Also in 1775, Massachusetts Spy publisher Isaiah Thomas moved his radical newspaper out of British occupied Boston to Worcester. Thomas would continuously publish his paper throughout the American Revolutionary War. On July 14, 1776, Thomas performed the first public reading in Massachusetts of the Declaration of Independence from the porch of the Old South Church, where the 19th century Worcester City Hall stands today. He would later go on to form the American Antiquarian Society in Worcester in 1812.

During the turn of the 19th century Worcester’s economy moved into manufacturing. Factories producing textiles, shoes and clothing opened along the nearby Blackstone River. However, the manufacturing industry in Worcester would not begin to thrive until the opening of the Blackstone Canal in 1828 and the opening of the Worcester and Boston Railroad in 1835. The city transformed into a transportation hub and the manufacturing industry flourished. Worcester was officially chartered as a city on February 29, 1848. The city’s industries soon attracted immigrants of primarily Irish, Scottish, French, German, and Swedish descent in the mid-19th century and later many immigrants of Lithuanian, Polish, Italian, Greek, Turkish and Armenian descent. Immigrants moved into new three-decker houses which lined hundreds of Worcester’s expanding streets and neighborhoods.

In 1831, Ichabod Washburn opened the Washburn & Moen Company. The company would become the largest wire manufacturing in the country and Washburn became one of the leading industrial and philanthropic figures in the city.

Worcester would become a center of machinery, wire products and power looms and boasted large manufacturers, Washburn & Moen, Wyman-Gordon Company, American Steel & Wire, Morgan Construction and the Norton Company. In 1908 the Royal Worcester Corset Company was the largest employer of women in the United States.

Worcester would also claim many inventions and firsts. New England Candlepin bowling was invented in Worcester by Justin White in 1879. Esther Howland began the first line of Valentine’s Day cards from her Worcester home in 1847. Loring Coes invented the first monkey wrench and Russell Hawes created the first envelope folding machine. On June 12, 1880, Lee Richmond pitched the first perfect game in Major league baseball history for the Worcester Ruby Legs at the Worcester Agricultural Fairgrounds.

On June 9, 1953, an F4 tornado touched down in Petersham, Massachusetts, northwest of Worcester. The tornado tore through 48 miles of Worcester County including a large area of the city of Worcester. The tornado left massive destruction and killed 94 people. The Worcester Tornado would be the most deadly tornado ever to hit Massachusetts. Debris from the tornado landed as far away as Dedham, Massachusetts.

After World War II, Worcester began to fall into decline as the city lost its manufacturing base to cheaper alternatives across the country and overseas. Worcester felt the national trends of movement away from historic urban centers. The city’s population dropped over 20% from 1950 to 1980. In the mid-20th century large urban renewal projects were undertaken to try to reverse the city’s decline. A huge area of downtown Worcester was demolished for new office towers and the 1,000,000 sq. ft. Worcester Center Galleria shopping mall. After only 30 years the Galleria would lose most of its major tenants and its appeal to more suburban shopping malls around Worcester County. In the 1960s, Interstate 290 was built right through the center of Worcester, permanently dividing the city. In 1963, Worcester native Harvey Ball introduced the iconic yellow smiley face to American culture.

In the late 20th century, Worcester’s economy began to recover as the city expanded into biotechnology and healthcare fields. The UMass Medical School has become a leader in biomedical research and the Massachusetts Biotechnology Research Park has become a center of medical research and development. Worcester hospitals Saint Vincent Hospital and UMass Memorial Health Care have become two of the largest employers in the city. Worcester’s many colleges, including the College of the Holy Cross, Worcester Polytechnic Institute, Clark University, UMass Medical School, Assumption College, MCPHS University, Becker College, and Worcester State University, attract many students to the area and help drive the new economy.

On December 3, 1999, a homeless man and his girlfriend accidentally started a five-alarm fire at the Worcester Cold Storage & Warehouse Company. The fire took the lives of six firemen and drew national attention as one of the worst firefighting tragedies of the late 20th century. President Bill Clinton, Vice President Al Gore and other local and national dignitaries attended the funeral service and memorial program in Worcester.

In recent decades, a renewed interest in the city’s downtown has brought new investment and construction to Worcester. A Convention Center was built along the DCU Center arena in downtown Worcester in 1997. In 2000, Worcester’s Union Station reopened after 25 years of neglect and a $32 million renovation. Hanover Insurance helped fund a multimillion-dollar renovation to the old Franklin Square Theater into the Hanover Theatre for the Performing Arts. In 2000, the Massachusetts College of Pharmacy and Health Sciences built a new campus in downtown Worcester. In 2007 WPI opened the first facility in their new Gateway Park center in Lincoln Square. In 2004, Berkeley Investments proposed demolishing the old Worcester Center Galleria for a new mixed-used development called City Square. The ambitious project looked to reconnect old street patterns while creating a new retail, commercial and living destination in the city. After struggling to secure finances for a number of years, Hanover Insurance took over the project and demolition began on September 13, 2010. Unum Insurance and the Saint Vincent Hospital leased into the project and both facilities opened in 2013. The new Front Street opened on December 31, 2012. In July 2017, Massachusetts Lieutenant Governor Karyn Polito and other Baker administration transportation officials visited a construction project in the city to highlight $2.8 billion spent during Baker’s administration on highway construction projects and improvements to bridges, intersections, and sidewalks.

Building off its history of immigration, Worcester has also become a home for many refugees in recent years. The city has successfully resettled over 2000 refugees coming from over 24 countries. Today, most of these refugees come from the Democratic Republic of the Congo, Iraq, Somalia, Bhutan, Syria, Ukraine and Afghanistan.

Worcester has a total area of 38.6 square miles (100 km²), 37.6 square miles (97 km²) of land and 1.0 square mile (2.6 km²) (roughly 2.59%) of water. Worcester is bordered by the towns of Auburn, Grafton, Holden, Leicester, Millbury, Paxton, Shrewsbury, and West Boylston.

Worcester is known as the Heart of the Commonwealth, because of its proximity to the center of Massachusetts. The city is about 40 miles (64 km) west of Boston, 50 miles (80 km) east of Springfield, and 38 miles (61 km) northwest of Providence, Rhode Island.

The Blackstone River forms in the center of Worcester by the confluence of the Middle River and Mill Brook. The river courses underground through the center of the city, and emerges at the foot of College Hill. It then flows south through Quinsigamond Village and into Millbury. Worcester is the beginning of the Blackstone Valley that frames the river. The Blackstone Canal was once an important waterway connecting Worcester to Providence and the Eastern Seaboard, but the canal fell into disuse at the end of the 19th century and was mostly covered up. In recent years, local organizations, including the Canal District Business Association, have proposed restoring the canal and creating a Blackstone Valley National Park. In November 2018, the administration of Massachusetts Governor Charlie Baker announced a $400,000 grant to streetscape improvements in the Canal District.

Worcester is one of many cities claimed, like Rome, to be found on seven hills: Airport Hill, Bancroft Hill, Belmont Hill (Bell Hill), Grafton Hill, Green Hill, Pakachoag Hill and Vernon Hill. However, Worcester has more than seven hills including Indian Hill, Newton Hill, Poet’s Hill, and Wigwam Hill.

Worcester has many ponds and two prominent lakes: Indian Lake and Lake Quinsigamond. Lake Quinsigamond (also known as Long Pond) stretches four miles across the Worcester and Shrewsbury border and is a very popular competitive rowing and boating destination.

Worcester’s humid continental climate (Köppen Dfb) is typical of New England. The weather changes rapidly owing to the confluence of warm, humid air from the southwest; cool, dry air from the north; and the moderating influence of the Atlantic Ocean to the east. Summers are typically hot and humid, while winters are cold, windy, and snowy. Snow typically falls from the second half of November into early April, with occasional falls in October; May snow is much rarer. The USDA classifies the city as straddling hardiness zones 5b and 6a.

The hottest month is July, with a 24-hour average of 70.2 °F (21.2 °C), while the coldest is January, at 24.1 °F (−4.4 °C). There is an average of only 3.5 days of 90 °F (32 °C)+ highs and 4.1 nights of lows at or below 0 °F (−18 °C) per year, and periods of both extremes are rarely sustained. The all-time record high temperature is 102 °F (39 °C), recorded on July 4, 1911, the only 100 °F (38 °C) or greater temperature to date. The all-time record low temperature is −24 °F (−31 °C), recorded on February 16, 1943.

The city averages 48.1 inches (1,220 mm) of precipitation a year, as well as an average of 40–50 inches (100–130 cm) of snowfall a season, receiving far more snow than coastal locations less than 40 miles (64 km) away. Massachusetts’ geographic location, jutting out into the North Atlantic, makes the city very prone to Nor’easter weather systems that can dump heavy snow on the region.

While rare, the city has had its share of extreme weather. On September 21, 1938, the city was hit by the brutal New England Hurricane of 1938. Fifteen years later, Worcester was hit by a tornado that killed 94 people. The deadliest tornado in New England history, it damaged a large part of the city and surrounding towns. It struck Assumption Preparatory School, now the site of Quinsigamond Community College.

According to the 2010 U.S. Census, Worcester had a population of 181,045, of which 88,150 (48.7%) were male and 92,895 (51.3%) were female. In terms of age, 77.9% were over 18 years old and 11.7% were over 65 years old; the median age is 33.4 years. The median age for males is 32.1 years and 34.7 years for females.

In terms of race and ethnicity, Worcester’s population was 69.4% White, 11.6% Black or African American, 0.4% American Indian and Alaska Native, 6.1% Asian (3.0% Vietnamese, 0.9% Chinese, and 0.8% Asian Indian), <0.1% Native Hawaiian and Other Pacific Islander, 8.4% from Some Other Race, and 4.0% from Two or More Races (1.2% White and Black or African American; 1.0% White and Some Other Race). Hispanics and Latinos of any race made up 20.9% of the population (12.7% Puerto Rican).Non-Hispanic Whites were 59.6% of the population in 2010, down from 96.8% in 1970.

Data is from the 2009–2013 American Community Survey 5-Year Estimates.

Worcester is governed by a Council-manager government with a popularly elected mayor. A city council acts as the legislative body, and the council-appointed manager handles the traditional day-to-day chief executive functions.

City councilors can run as either a representative of a city district or as an at-large candidate. The winning at-large candidate who receives the greatest number of votes for mayor becomes the mayor (at-large councilor candidates must ask to be removed from the ballot for mayor if they do not want to be listed on the mayoral ballot). As a result, voters must vote for their mayoral candidate twice, once as an at-large councilor, and once as the mayor. The mayor has no more authority than other city councilors, but is the ceremonial head of the city and chair of the city council and school committee. Currently, there are 11 councilors: 6 at-large and 5 district.

Worcester’s first charter, which went into effect in 1848, established a Mayor/Bicameral form of government. Together, the two chambers — the 11-member Board of Aldermen and the 30-member Common Council — were vested with complete legislative powers. The mayor handled all administrative departments, though appointments to those departments had to be approved by the two-chamber City Council.

Seeking to replace the 1848 charter, Worcester voters in November 1947 approved a change to Plan E municipal government. In effect from January 1949 until November 1985, this charter (as outlined in chapter 43 of the Massachusetts General Laws) established City Council/City Manager government. This type of governance, with modifications, has survived to the present day.

Initially, Plan E government in Worcester was organized as a 9-member council (all at-large), a ceremonial mayor elected from the council by the councilors, and a council-appointed city manager. The manager oversees the daily administration of the city, makes all appointments to city offices, and can be removed at any time by a majority vote of the council. The mayor chairs the city council and the school committee, and does not have the power to veto any vote.

From 1949 through 1959, elections were by the single transferable vote. Voters repealed that system in November 1960. Despite non-partisan elections, two groups alternated in control of council: the local Democratic Party and a slate known as the Citizens’ Plan E Association (CEA). CEA members included the Republican Party leadership and other groups not affiliated with the regular Democratic Party.

In 1983, Worcester voters again decided to change the city charter. This “Home Rule” charter (named for the method of adoption of the charter) is similar to Plan E, the major changes being to the structure of the council and the election of the mayor. The 9-member Council became 11, 6 at-large and 1 from each city district. The mayor is chosen by popular election, but must also run and win as an at-large councilor.

Worcester’s history of social progressivism includes a number of temperance and abolitionist movements. It was a leader in the women’s suffrage movement: The first national convention advocating women’s rights was held in Worcester, October 23–24, 1850.

Two of the nation’s most radical abolitionists, Abby Kelley Foster and her husband Stephen S. Foster, adopted Worcester as their home, as did Thomas Wentworth Higginson, the editor of The Atlantic Monthly and Emily Dickinson’s avuncular correspondent, and Unitarian minister Rev. Edward Everett Hale.

The area was already home to Lucy Stone, Eli Thayer, and Samuel May, Jr. They were joined in their political activities by networks of related Quaker families such as the Earles and the Chases, whose organizing efforts were crucial to the anti-slavery cause in central Massachusetts and throughout New England.

Anarchist Emma Goldman and two others opened an ice cream shop in 1892. “It was spring and not yet warm,” Goldman later wrote, “but the coffee I brewed, our sandwiches, and dainty dishes were beginning to be appreciated. Within a short time, we were able to invest in a soda-water fountain and some lovely colored dishes.”

On October 19, 1924, the largest gathering of the Ku Klux Klan (KKK) ever held in New England took place at the Agricultural Fairgrounds in Worcester. Klansmen in sheets and hoods, new Knights awaiting a mass induction ceremony, and supporters swelled the crowd to 15,000. The KKK had hired more than 400 “husky guards”, but when the rally ended around midnight, a riot broke out. Klansmen’s cars were stoned and burned, and their windows smashed. KKK members were pulled from their cars and beaten. Klansmen called for police protection, but the situation raged out of control for most of the night. The violence after the “Klanvocation” had the desired effect: Membership fell off, and no further public Klan meetings were held in Worcester.

Robert Stoddard, owner of The Telegram and Gazette, was one of the founders of the John Birch Society.

Sixties era radical Abbie Hoffman was born in Worcester in 1936 and spent more than half of his life in the city.

For public safety needs, the City of Worcester is protected by both the Worcester Fire Department and the Worcester Police Department.

UMass Memorial Medical Center provides emergency medical services (EMS) under contract with the city. Originally operated by Worcester City Hospital and later by the University of Massachusetts Medical School, “Worcester EMS” operates exclusively at the advanced life support (ALS) level, with two paramedics staffing each ambulance. UMass Memorial EMS maintains two community EMS stations and operates a fleet of 18 ambulances (including spares), as well as a special-operations trailer, several other support vehicles, and a bike team; the agency responds to an average of 100 emergencies each day. UMass Memorial EMS operates the EMS Communications Center, which is a secondary PSAP and provides emergency medical dispatch (EMD) services to Worcester and other communities.
