The story

History

Native people

The earliest evidence of Native American settlement in the Miami region is from approximately 12,000 years ago. The first inhabitants settled on the banks of the Miami River, with the main villages on the northern banks.

The inhabitants at the time of first European contact were the Tequesta people, who controlled much of southeastern Florida, including present-day Miami-Dade County, Broward County, and the southern part of Palm Beach County. The Tequesta Indians fished, hunted, and gathered the fruit and roots of plants for food, but did engage in agriculture. They buried the small bones of the deceased with the rest of the body, and put the larger bones in a box for the village people to see. The Tequesta are credited with making the Miami Circle.

European explorers and settlers

Juan Ponce de León was the first European to visit the area in 1513 by sailing into Biscayne Bay. His journal records he reached Chequescha, a variant of Tequesta, which was Miami's first recorded name. It is unknown whether he came ashore or made contact with the natives. Pedro Menéndez de Avilés and his men made the first recorded landing when they visited the Tequesta settlement in 1566 while looking for Avilés' missing son, shipwrecked a year earlier. Spanish soldiers led by Father Francisco Villarreal built a Jesuit mission at the mouth of the Miami River a year later but it was short-lived. After the Spaniards left, the Tequesta Indians were left to fend themselves from European-introduced diseases like smallpox. By 1711, the Tequesta sent a couple of local chiefs to Havana, Cuba, to ask if they could migrate there. The Spanish sent two ships to help them, but Spanish illnesses struck and most of the Tequesta died.

The first permanent European settlers arrived in the early 19th century. People came from the Bahamas to South Florida and the Keys to hunt for treasure from the ships that ran aground on the treacherous Great Florida Reef. Some accepted Spanish land offers along the Miami River. At about the same time, the Seminole Indians arrived, along with a group of runaway slaves. The area was affected by the Second Seminole War, during which Major William S. Harney led several raids against the Indians. Most non-Indian residents were soldiers stationed at Fort Dallas. It was the most devastating Indian war in American history, causing almost a total loss of population in Miami.

After the Second Seminole War ended in 1842, William English re-established a plantation started by his uncle on the Miami River. He charted the "Village of Miami" on the south bank of the Miami River and sold several plots of land. In 1844, Miami became the county seat, and six years later a census reported there were ninety-six residents in the area. The Third Seminole War was not as destructive as the second, but it slowed the settlement of southeast Florida. At the end of the war, a few of the soldiers stayed.

Establishment

Dade County was created on February 4, 1836, under the Territorial Act of the United States. The county was named after Major Francis L. Dade, a soldier killed in 1835 in the Second Seminole War, at what has since been named the Dade Battlefield.

Originally, the county was set to be named "Pinckney County", after Thomas Pinckney, a statesman and diplomat from South Carolina who drafted the Treaty of San Lorenzo. The county's credited father, Richard Fitzpatrick, preferred this name as he was from South Carolina himself; however, when news reached Tallahassee of the Dade Massacre, the Territorial Legislative Council inserted Dade's name instead into a pending bill to create the new county.

At the time of its creation, Dade County included the land that now contains Palm Beach and Broward counties, together with the Florida Keys from Bahia Honda Key north and the land of present-day Miami-Dade County. The county seat was originally at Indian Key in the Florida Keys; then in 1844, the County seat was moved to Miami. The Florida Keys from Key Largo to Bahia Honda were returned to Monroe County in 1866. In 1888 the county seat was moved to Juno, near present-day Juno Beach, Florida, returning to Miami in 1899. In 1909, Palm Beach County was formed from the northern portion of what was Dade County, and then in 1915, Palm Beach County and Dade County contributed nearly equal portions of land to create what is now Broward County. There have been no significant boundary changes to the county since 1915.

Hurricane Andrew

The third-costliest natural disaster to occur in the United States was Hurricane Andrew, which hit Miami in the early morning of Monday, August 24, 1992. It struck the southern part of the county from due east, south of Miami and very near Homestead, Kendall, and Cutler Ridge, which was later renamed Cutler Bay. Damages exceeded US$25 billion in the county, and recovery took years in these areas where the destruction was greatest. Hurricane Andrew was the costliest natural disaster in U.S. history until Hurricane Katrina struck the Gulf region in 2005.

Name change

Miami-Dade County has previously attempted to change its name 5 times between 1958 and 1990, with voters rejecting each proposal. Below are the results of the previous elections to change the county's name:

On November 13, 1997, voters changed the name of the county from "Dade County" to "Miami-Dade County" to acknowledge the international name recognition of Miami. Voters were acting pursuant to home rule powers granted to Dade County, including the ability to change the name of the county without the consent of the Florida Legislature. With the name change, Miami-Dade County became the only county in the United States whose name was hyphenated.

Public libraries

The Miami-Dade Public Library System traces its origin to the late nineteenth century. The first library was a reading room established in Lemon City on April 7, 1894, by the Lemon City Library and Improvement Association. In 1942 neighborhood libraries were brought together in a single public library system, governed by a board of trustees and administered by a Head Librarian. A new central library building had been proposed for Bayfront Park in Downtown Miami as early as 1938, but the proposal was not realized till over a decade later. In December 1965 the City of Miami and Metropolitan Dade County agreed that the City of Miami would provide public library service to unincorporated Dade County and to those municipalities that did not provide their library service with four bookmobiles provided library service to the unincorporated area. On November 1, 1971, the City of Miami transferred its library system to Metropolitan Dade County which created a new Department of Libraries with a Director reporting directly to the County Manager.

On November 7, 1972, Dade County voters approved a referendum, also known as the "Decade of Progress" bonds, authorized approximately $553 million for public improvement projects in Dade County. Of that amount, approximately $34.7 million was authorized for public libraries, including construction, renovation, land acquisition, furnishings, and equipment. Between 1976 and 1990, this bond issue provided the funds to open 14 new libraries. On August 24, 1992, Hurricane Andrew inflicted significant damage on the library system, destroying all branches south of Kendall Drive. Over the next years, no further expansion of the system was funded and no new libraries opened. It was not until the fall of 2001, when Mayor Alex Penelas and Board of County Commissioners voted to increase the library system's budget which provided funding for capital improvement initiatives—making way for the opening of 18 new libraries by 2011. As of 2017, 15 of these libraries have been opened, with the remaining 3 still under construction.

Today Miami-Dade Public Library System serves a population of 2,496,435, provides services for the Miami-Dade County except for the cities of Bal Harbour, Hialeah, Homestead, Miami Shores, North Miami, North Miami Beach and Surfside. It has forty-nine branches, two bookmobiles and one technobus. The Miami-Dade County Board of County Commissioners governs the Miami-Dade Public Library System.
