The first people to inhabit the area now called Polk County arrived close to 12,000 years ago during the last ice age as the first paleo-indians following big game southward reached the peninsula of Florida. By this time, the peninsula had gone through several expansions and contractions due to changing sea level; at times the peninsula was much wider than it is today, while at other times it was almost entirely submerged with only a few small islands exposed. These first paleo-indians, nomadic hunter/gatherers who did not establish any permanent settlements, eventually gave way to the "archaic people". These were ancestors of the historic Native Americans who came in contact with the Spaniards when they arrived on the peninsula. These Native Americans thrived on the peninsula. It is estimated that there were more than 250,000 in 1492 when Columbus set sail for the New World. As was common elsewhere in the Americas, contact with Europeans had a devastating effect on the Native Americans. Smallpox, measles, and other diseases, to which the Native Americans had no immunity, caused widespread epidemic and death. Those who had not succumbed to diseases such as these were often either killed or enslaved as Spanish explorers and settlers arrived. Within a few hundred years, nearly the entire pre-Columbian population of Polk County had been wiped out.
For around 250 years after Ponce De Leon arrived on the peninsula, the Spanish nominally ruled Florida but established few settlements. In the late 17th century, Florida went through an unstable period in which the French and British ruled the peninsula. By this time, the remnants of early Native Americans joined with refugee Creek Native Americans from Georgia and The Carolinas to form the Seminole Indian Tribe, through a process of ethnogenesis. After the American Revolution, the peninsula briefly reverted to Spanish rule. In 1819, Florida became a U.S. territory as a result of the Adams-Onis Treaty. From the 1830s until 1842, the US conducted the Seminole Wars in an effort to remove the Seminole from the territory. Some were removed to Indian Territory, but others retreated to the Everglades and never surrendered.
While Florida gained statehood in 1845, it was not until 1861 that Polk County was created from the eastern part of Hillsborough County. It was named in honor of former US President James K. Polk, 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 acres (0.49 km2) 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 name to Bartow. 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 IIEdit
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 1895-1921; 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 sherriff, arrested, and then turned over to a mob that shot him 40-t0 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 presentEdit
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.
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.
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. Country musician Gram Parsons was from a wealthy family in Winter Haven.
In 2018 the Lakeland City Commission voted to move the Confederate monument, installed in 1910 at Munn Park in Lakeland, to Veterans Memorial Park. This was the location of the original African-American community of Moorehead, which was first settled in 1883. 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 land 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.
According to the U.S. Census Bureau, the county has a total area of 2,011 square miles (5,210 km2), of which 1,798 square miles (4,660 km2) is land and 213 square miles (550 km2) (10.6%) is water. It is the fourth-largest county in Florida by land area and fifth-largest by total area.
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 (-3.9 °C to -1.1 °C). 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 will move inland, colliding in Polk County to form especially strong thunderstorms.:589 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.:590–591
The Green Swamp is prone to fog in winter. In the pre-dawn 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 ten separate crashes that resulted in five deaths. A 2017 study by the Climate Impact Lab determined that among the 131 U.S. counties with more than 500,000 residents, Polk County would be the most economically impacted (as a percentage of GDP) by climate change by the end of the twenty-first century.

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 (153 km/h) sustained and a gust of 101 mph (163 km/h). 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 (175 km/h) was recorded by emergency management officials. The hurricane-force wind field was relatively narrow, with the most intense wind damage being within 10 mi (16 km) of the center of the eye. For example maximum recorded winds were only 41 kn (76 km/h; 47 mph) sustained and a gust of 54 kn (100 km/h; 62 mph) at Gilbert Airport on the northwest side of the city.

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 Class A-Advanced 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.
Government and politicsEdit
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. Melony Bell, from Fort Meade, serves as a County Commissioner.
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.

Universities and collegesEdit
The Polk County Library Cooperative was formed October 1, 1997 through an Interlocal Agreement between the 13 municipalities with public libraries and the Board of County Commissioners. The Cooperative enables the city-owned and -operated public libraries to open their doors to all residents of the county, including those in the unincorporated area.
Interlibrary Loan (ILL) offers library patrons the opportunity to request and receive books that are not owned by the Winter Haven Public Library. Through ILL, not only do patrons have access to the circulating book collections of all the library systems in Polk County but also all of the library systems in Florida, as well as universities and public library systems throughout the United States.
Cooperative member librariesEdit
Polk County Historical & Genealogical LibraryEdit
The Polk County Historical & Genealogical Library was established in 1937. It 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 ten-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 (BoCC) and administered by the Neighborhood Services Department and the Leisure of Services Division. The library holds one of the largest genealogical and historical collections in the Southeast United States.
Collections and Services
The Polk County Historical & Genealogical Library holds more than 40,000 items in its collection. The collection includes books, microfilm, and periodicals that include 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.
