Polk County, Florida

Polk County is a county located in the central portion of the U.S. state of Florida. The county population was 725,046, as of the 2020 census, and estimated to be 818,330, as of July 1, 2023. Its county seat is Bartow, and its largest city is Lakeland.

Polk County comprises the Lakeland–Winter Haven metropolitan statistical area (MSA). This MSA is the 77th-most populous one and the 89th-most populous primary statistical area of the United States as of July 1, 2012.

The center of population of Florida is located in Polk County, near the city of Lake Wales. Polk County is home to one public university, one state college, and four private universities.

Early history
The first people to inhabit the area now called Polk County were the Paleoindians who arrived in Florida at least 12,000 years ago, late in the last ice age. With large amounts of water locked up in continental ice caps, the sea level was more than 150 ft lower than at present. The Florida peninsula was twice as wide as it is today, and Florida was cooler and much drier, with few, if any, flowing rivers. Both animals and humans were dependent on scattered water holes, such as sinkholes, deep holes in otherwise dry river beds, and rain-fed lakes perched on impervious clay. Most Paleoindian campsites found in Florida have been found at water holes. The largest collection of late (more than 9,500 years ago) Paleoindian microlithic tools known from Florida were found in Lake Weohyakapka, near Nalcrest in Polk County.

As sea levels rose and Florida became warmer and wetter, the Paleoindian period was followed by the Archaic period, which ended 2,500 to 3,000 years ago, with the emergence of recognizable archaeological cultures in Florida. In eastern Polk County, the Kissimmee River valley was occupied by people of the Belle Glade culture, which persisted from about 3,000 years ago until the collapse of the Native American population in Florida after 1700. Native American people in western Polk County were part of, or influenced by, the Manasota culture, which flourished from 2,500 years ago until around 800 AD, when it was replaced by the Safety Harbor culture, from circa 800 until after 1700. The Peace River valley may have hosted a distinct culture during the Safety Harbor period.

In 1539, Ponce De Leon sent a detachment (between 80 and 180 men) of his expedition from his landing place on Tampa Bay across northern Polk County to visit Urriparacoxi, a powerful chief based in southern Lake County or eastern Orange County. For the next 280 years, the Spanish (and, between 1763 and 1783, the British) ruled Florida, but did not venture into the interior of the Florida peninsula south of the Oklawaha River valley (Acuera Province). The indigenous peoples of the Florida peninsula declined in numbers, and the people who became known as the Seminole moved into central Florida.

United States control
In 1821, Florida became a U.S. territory as a result of the Adams-Onis Treaty. In 1823, the Treaty of Moultrie Creek created a reservation in central Florida for the Seminoles and other Native Americans in Florida. What is now Polk County was within the boundaries of that reservation. An attempt to remove all Native Americans in Florida to west of the Mississippi River, starting in 1832, led to the Second Seminole War. Most of the fighting in the early years of the war occurred north of Polk County. By 1837, the Seminoles were being pushed south, and late that year, Colonel Zachary Taylor, as part of a coordinated push against the Seminoles, led a column east from Fort Brooke (today's Tampa) into what is now Polk County, and then south between the Kissimmee and Peace River valleys, culminating in the Battle of Lake Okeechobee. By 1843 the few Seminoles remaining in Florida were confined to an informal reservation in southern Florida.

While Florida gained statehood in 1845, Polk County was not created until a month after Florida had seceded from the Union. It was formed from the eastern part of Hillsborough County and named in honor of former US President James K. Polk, who had been popular with Southerners for supporting the expansion of slavery and whose 1845 inauguration was on the day after Florida became a state.

Following the Civil War, the county commission established the county seat on 120 acre donated in the central part of the county. Bartow, the county seat, was named after Francis S. Bartow, a Confederate colonel from Georgia who was the first Confederate brigade commander to die in battle. Colonel Bartow was buried in Savannah, Georgia, with military honors, and promoted posthumously to the rank of brigadier general. The original name of the town was Fort Blount. Several other towns and counties in the South changed their names to Bartow to honor the brigade commander. The first courthouse built in Bartow was constructed in 1867. It was replaced twice, in 1884 and in 1908. As the third courthouse to stand on the site, the present structure houses the Polk County Historical Museum and Genealogical Library. After the Civil War, some 400 Confederate veterans settled here with families before the end of the century.

Post-Reconstruction era to World War II
In the post-Reconstruction period, black railway workers were among the first African Americans to settle in Polk County, in 1883 south of Lake Wire. The following year, they founded St. John's Baptist Church, which also served as the first school for freedmen's children. Other workers arrived for jobs in the phosphate industry. This area became the center of a predominately African-American community later known as Moorehead, after Rev. H.K. Moorehead, called to St. John's in 1906. The community developed its own businesses, professional class, and cultural institutions. Its students had to go to other cities for high school until 1928, when the first upper school to serve blacks was established here.

White violence rose against blacks in the late 19th century in a regionwide effort to establish and maintain white supremacy as Southern states disenfranchised most blacks and imposed Jim Crow. Whites lynched 20 African Americans in Polk County from 1895 to 1921; Three black men, whose names were not recorded, were murdered in a mass lynching on May 25, 1895, accused of rape. While others were killed for alleged crimes (never proven), one black man was lynched for supposedly insulting a white woman. The man, Henry Scott, was a porter on a train from Lakeland to Bartow. While he was preparing a berth for one woman on May 20, 1920, another white woman became angry that he made her wait. She sent a telegram to the next station where he was met by a sheriff, arrested, and then turned over to a mob that shot him 40-50 times. Columbia County also had 20 such lynching murders; these two counties had the second-highest total of lynchings of African Americans of any county in the state.

In the first few decades of the 1900s, thousands of acres of land around Bartow were purchased by the phosphate industry. The county seat became the hub of the largest phosphate industry in the United States, attracting both immigrants and African-American and white workers from rural areas.

Polk County was the leading citrus county in the United States for much of the 20th century, and even the county seat Bartow has had several large groves. In 1941, the city built an airport northeast of town in the county. The airport was taken over by the federal government during World War II and was the training location for many Army Air Corps pilots during the war. The airport was returned to the city in 1967 and renamed as Bartow Municipal Airport.

Mid-20th century to present
In the 20th century, the Ku Klux Klan revived and was active in Polk County, even after World War II. Klansmen were photographed in hoods and robes in 1958 in a church in Mulberry. During the 1960s, violence related to civil-rights movement was attributed to the Klan. In 1967, a white man shot and severely wounded a popular African-American high-school football player who was integrating Lake Ariana Beach. A Klan group marched in Lakeland in full regalia in 1979, their last public march by the Confederate monument in Munn Park.

Fred Rochelle, 16, was burned alive in a public spectacle lynching before thousands in Polk County, Florida, in 1901.

Since the late 20th century, growth in Polk County has been driven by its proximity to both the Tampa and Orlando metropolitan areas along the Interstate 4 corridor. Recent growth has been heaviest in Lakeland (closest to Tampa) and the northeast areas near Haines City (nearest to Orlando). From 1990 to 2000, unincorporated areas grew 25%, while incorporated areas grew only 11%. In addition to cottage communities that have developed for commuters, Haines City has suburban sprawl into unincorporated areas. Despite the impressive growth rate, the unemployment rate of Polk has typically been higher than that of the entire state. For example, in August 2010, the county had an unemployment rate of 13.4%, compared to 11.7% for the entire state.

During the 2004 Atlantic hurricane season, three hurricanes, Charley, Frances, and Jeanne, all tracked over Polk County, intersecting in a triangle that includes the city of Bartow.

Winter Haven was best known as the home of the Cypress Gardens theme park, which operated from 1936 to September 23, 2009. Legoland Florida has since been built on the site of former Cypress Gardens, and has preserved the botanical garden section. Winter Haven was the location of the first Publix supermarket circa 1930; today, Publix's corporate offices are located in Lakeland.

In 2018, the Lakeland City Commission voted to move the Confederate monument from Munn Park, where it was installed in 1910, to Veterans Memorial Park. What is now Veterans Memorial Park was first settled in 1883 as the community of Moorehead, the original African-American community in the area. Owners were bought out in 1967 by eminent domain for county civic development of a conference center and the later Veterans Memorial Park. Some members of the black community have objected to the Confederate monument being relocated to the site of what had been their historic community in Lakeland, saying it would be more appropriate to be located in the cemetery with numerous Confederate graves.

Geography
According to the U.S. Census Bureau, the county has a total area of 2011 sqmi, of which 213 sqmi (10.6%) are covered by water. It is the fourth-largest county in Florida by land area and fifth-largest by total area.

Polk County is within the Central Florida Highlands area of the Atlantic coastal plain, with a terrain consisting of flatland interspersed with gently rolling hills. Part of the Lake Wales Ridge runs through eastern Polk County, which is known for its rolling hills with unique wildlife and plants. The highest elevation in the county is Crooked Lake Sandhill at 305 feet, with the second-highest being Iron Mountain, the location of Bok Tower at 295 feet above sea level. Several artificial raised phosphate tailings ponds in the center of the county rise up to 375 feet.

Adjacent counties
In addition, at its northeast corner, Polk County touches Orange County at a quadripoint called Four Corners, Florida; Lake and Osceola Counties lie between.

Climate
Polk County, like most of Florida, has a humid subtropical climate (Köppen Cfa). It lies in the USDA plant hardiness zone 9b, where the average annual minimum temperature is 25 - 30 F. The last measurable snow in the county fell in 1977, but snow flurries and sleet fell on January 8, 2010, over the course of an hour on an exceptionally cold day.

During the summer rainy season from June to September, sea breezes from both coasts move inland, where the moist air is heated and rises to form thunderstorms. On many days, the sea-breeze thunderstorms from both coasts move inland, colliding in Polk County to form especially strong thunderstorms. Polk County is located in the middle of "lightning alley", which has more lightning annually than any region in the United States. Largely due to its size, the county receives the overall highest number of lightning strikes in the area.

The Green Swamp is prone to fog in winter. In the predawn hours of January 8, 2008, smoke from a prescribed burn contributed to especially dense fog on Interstate 4 that caused a major pileup involving 70 vehicles in 10 separate crashes that resulted in five deaths.

Tropical cyclones
The eyes of 12 hurricanes have passed through the county at hurricane strength in recorded history, including Hurricane Irma (2017, category 1), Hurricane Jeanne (2004, category 1), Hurricane Charley (2004, category 2), Hurricane Donna (1960, category 2), Hurricane King (1950, category 1), the 1949 Florida hurricane (category 2), the 1945 Homestead hurricane (category 1), the 1933 Treasure Coast hurricane (category 1), the 1928 Okeechobee hurricane (category 2), Hurricane Four of the 1894 season (category 1), and Hurricane Three of the 1871 season, and Hurricane Eight of the 1859 season (category 1). Additionally, four storms were downgraded from hurricane strength at a location outside the county to tropical storm force at some point within the county and, given the hours between National Hurricane Center updates (modern era) or earlier estimates, it is not clear whether these brought hurricane-force sustained winds to Polk County: Hurricane Frances (2004), Hurricane Erin (1995) Hurricane Two of the 1939 season, and the 1910 Cuba hurricane (category 1). Numerous tropical storms have passed through the county.

Hurricane Charley in 2004—the first of three hurricanes to hit the county in six weeks—is the strongest storm in recent history to pass through the county, mainly impacting the eastern half of the county. The Lake Wales Fire Department recorded an unofficial maximum wind speed of 95 mph sustained and a gust of 101 mph. The hurricane entered the county south of Fort Meade, shortly after it passed Wauchula (in Hardee County), where a maximum wind gust of 109 mph was recorded by emergency management officials. The hurricane-force wind field was relatively narrow, with the most intense wind damage being within 10 mi of the center of the eye. For example, maximum recorded winds were only 41 kn sustained and a gust of 54 kn at Gilbert Airport on the northwest side of the city.

Sports
Polk County is home to professional baseball and basketball teams and boasts a rich history of collegiate sports competition at a number of its institutions of higher learning, including perennial NCAA Division II national championship contender and titleholder (in multiple sports), Florida Southern College.

Professional baseball, especially major league spring training, was historically a major generator of tourist traffic for Polk County. Today, however, only the Detroit Tigers remain for spring training. Additionally, the Single-A Lakeland Flying Tigers play in Joker Marchant Stadium after spring training.

Professional basketball made its debut in 2017 when the Lakeland Magic took the court in its home venue, RP Funding Center. The team is the NBA G League developmental affiliate of the NBA's Orlando Magic. In 2023, the team relocated from Polk County to Osceola County.

College sports are also popular in Polk County. The Florida Southern Moccasins play in NCAA Division II in the Sunshine State Conference. The Southeastern Fire play in NAIA Sun Conference.

Government and politics
The executive and legislative powers of the county are vested in the five-member board of county commissioners. While the county is divided into five separate districts, each commissioner is elected at-large, countywide, requiring them to gain majority support. Each term lasts for four years, with odd-numbered districts holding elections in presidential election years, and even-numbered districts holding elections two years later. Like all elected officials in the state, county commissioners are subject to recall. The commissioners elect a chairman and vice-chairman annually. The chairman selects the chairs of each committee, who work with the county manager to establish the policies of the board. The commission meets twice a month- generally every other Tuesday. Additional meetings take place as needed, but must be announced per the Florida sunshine laws.

Among the most important duties of the county commission is levying taxes and appropriations. The ad valorem millage rate levied by the county for county government purposes is 6.8665. The commission is responsible for providing appropriations for other countywide offices including the sheriff, property appraiser, tax collector, and supervisor of elections. The county and circuit court systems are also partially supported by the county budget, including the state attorneys and public defenders. A portion of the county's budget is dedicated to providing municipal-level services and regulations to unincorporated areas, such as zoning, business codes, and fire protection. Other services benefit both those in municipalities and in unincorporated Polk County, such as those that provide recreational and cultural opportunities.

The current Sheriff of Polk County is Grady Judd.

History
The Polk County Historical and Genealogical Library was established in 1937, and opened to the public in January 1940. The library was first located in the office of the county attorney and its holdings were all housed in a metal bookcase. Since then, the library has been housed in several different locations within the old Polk County Courthouse. In 1968, the library hired its first full-time employee. By 1974, the library added a second employee and was moved to a new location on Hendry Street. In 1987, the library relocated back to the 1908 Courthouse.

It was renovated during a 10-year process that included expansion to take over and adapt all three floors of the eastern wing of the courthouse. As of 2013, the library is located in the east wing of the historical courthouse in Bartow. It is governed by the Polk County Board of County Commissioners and administered by the Neighborhood Services Department and the Leisure Services Division. The library holds one of the largest genealogical and historical collections in the Southeastern United States.

Collections and services
The Polk County Historical and Genealogical Library holds more than 40,000 items in its collection, which includes books, microfilm, and periodicals with information about the history and genealogy of the entire Eastern United States. The selection of materials related to the history of Polk County contains local newspapers dated back to 1881, aerial photography to 1938, city directories to 1925 and property tax rolls to 1882. Four full-time staff members are available for assistance at the library. The library also offers local obituary searches and basic looks-ups via email.

Communities
According to the 2010 Census, just under 38% of the population of the county lives in one of Polk's seventeen incorporated municipalities. The largest city, Lakeland, has over 112,000 residents and is located in the western edge of the county. The other core city of the metropolitan area, Winter Haven, is located in the eastern part of the county and has 34,000 residents. The county seat, Bartow, is located southeast of Lakeland and southwest of Winter Haven and has over 17,000 residents. The cities of Bartow, Lakeland, and Winter Haven form a roughly equilateral triangle pointed downward with Bartow being the south point, Lakeland the west point, and Winter Haven the east point.

The other major cities in the county with a population over 10,000 include Haines City, Auburndale, and Lake Wales. Haines City is in the northeast part of the county and has over 20,000 residents. Auburndale is located northwest of Winter Haven and Lake Wales is around 16 miles east of Bartow.
