Adesivo Coat of arms of British Honduras-Belize, 1967-1981

British Honduras was a Crown colony on the east coast of Central America — specifically located on the southern edge of the Yucatan Peninsula from 1783 to 1964, then a self-governing colony — renamed Belize from June 1973 until September 1981, when it gained full independence as Belize. British Honduras was the last continental possession of the United Kingdom in the Americas. The colony grew out of the Treaty of Versailles (1783) between Britain and Spain, which gave the British rights to cut logwood between the Hondo and Belize rivers. The Convention of London (1786) expanded this concession to include the area between the Belize and Sibun rivers. In 1862, the Settlement of Belize in the Bay of Honduras was declared a British colony called British Honduras, and the Crown's representative was elevated to a lieutenant governor, subordinate to the governor of Jamaica. Belize is a country on the north-eastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a maritime boundary with Honduras to the southeast. Part of the Caribbean region, Belize is a member of the Caribbean Community (CARICOM) and the Commonwealth Caribbean, the historical British West Indies. The Maya civilization spread into the area of Belize between 1500 BCE and 300 CE and flourished until about 1200. European contact began in 1502–04 when Christopher Columbus sailed along the Gulf of Honduras. European exploration was begun by English settlers in 1638. Spain and Britain both laid claim to the land until Britain defeated the Spanish in the Battle of St. George's Caye (1798). It became a British colony in 1840, and a Crown colony in 1862. Belize achieved its independence from the United Kingdom on 21 September 1981. It is the only mainland Central American country which is a Commonwealth realm, with King Charles III as its monarch and head of state, represented by a governor-general. Belize's abundance of terrestrial and marine plants and animals and its diversity of ecosystems, including extensive coral reefs, give it a key place in the globally significant Mesoamerican Biological Corridor. It is considered a Central American and Caribbean nation with strong ties to both the American and Caribbean regions. It has an area of 22,970 square kilometres (8,867 sq mi) and a population of 397,483 (2022). Its mainland is about 290 km (180 mi) long and 110 km (68 mi) wide. It is the least populated and least densely populated country in Central America. Its population growth rate of 1.87% per year (2018 estimate) is the second-highest in the region and one of the highest in the Western Hemisphere. Its capital is Belmopan, and its largest city is the namesake city of Belize City. The country has a diverse society composed of many cultures and languages. It is the only Central American country where English is the official language. Belizean Creole and Spanish are widely spoken, followed by the Mayan languages and Garifuna. Over half the population is multilingual due to the diverse linguistic backgrounds of the population. It is known for its September Celebrations and punta music.
