Miami-Dade County (commonly called Miami, Miami-Dade, Dade County, Dade, Metro-Dade or Greater Miami) is a county located in the southeastern part of the state of Florida. As of 2010 U.S. Census, the county had a population of 2,496,435, making it the most populous county in Florida and the seventh-most populous county in the United States. It is also Florida's third largest county in terms of land area, with . The county contains approximately half of the Miami metropolitan area's population and several of its largest cities. The county seat is Miami.
The county is home to 35 incorporated cities and many unincorporated areas. The northern, central and eastern portions of the county are heavily urbanized with many high rises up the coastline, as well as the location of South Florida's central business district, Downtown Miami. Southern Miami-Dade County includes the Redland and Homestead areas, which make up the agricultural economy of Miami. Agricultural Redland makes up roughly one third of Miami-Dade County's inhabited land area, and is sparsely populated, a stark contrast to the densely populated, urban northern Miami-Dade County. The western portion of the county extends into the Everglades National Park and is populated only by a Miccosukee Tribal village. East of the mainland in Biscayne Bay is also Biscayne National Park and the Biscayne Bay Aquatic Preserves.
The earliest evidence of Native American settlement in the Miami region came from about 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 what is now 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 not practice any form of 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.
Juan Ponce de León was the first European to visit the area in 1513 by sailing into Biscayne Bay. His journal records that 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 Cubans sent two ships to help them, but Spanish illnesses struck and most of the Indians 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 the Miami area.
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 that there were ninety-six residents living in the area. The Third Seminole War was not as destructive as the second one. Even so, it slowed down the settlement of southeast Florida. At the end of the war, a few of the soldiers stayed.
Birth of Dade County
Dade County was created on January 18, 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. 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 then 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.
The second-costliest natural disaster to occur in the United States was Hurricane Andrew, which hit Miami early Monday morning on August 24, 1992. It struck the central part of the county from due east, south of Miami and very near Homestead, Kendall, and Cutler Ridge (now the Town of Cutler Bay). Damages numbered over US$25 billion in the county alone, and recovery has taken years in these areas where the destruction was greatest. This was the costliest natural disaster in US history until Hurricane Katrina struck the Gulf region in 2005.
On November 13, 1997, voters changed the name of the county from Dade to Miami-Dade to acknowledge the international name recognition of Miami.
