Andalusia (UK: /ˌændəˈluːsiə, -ziə/ AN-də-LOO-see-ə, -⁠zee-ə, US: /-ʒ(i)ə, -ʃ(i)ə/ -⁠zh(ee-)ə, -⁠sh(ee-)ə; Spanish: Andalucía [andaluˈθi.a] , locally also [-ˈsi.a]) is the southernmost autonomous community in Peninsular Spain, located in the south of the Iberian Peninsula, in southwestern Europe. It is the most populous and the second-largest autonomous community in the country. It is officially recognized as a historical nationality and a national reality. The territory is divided into eight provinces: Almería, Cádiz, Córdoba, Granada, Huelva, Jaén, Málaga, and Seville. Its capital city is Seville, while the seat of its High Court of Justice is the city of Granada.

Andalusia is immediately south of the autonomous communities of Extremadura and Castilla-La Mancha; west of the autonomous community of Murcia and the Mediterranean Sea; east of Portugal and the Atlantic Ocean; and north of the Mediterranean Sea and the Strait of Gibraltar. The British Overseas Territory and city of Gibraltar, located at the eastern end of the Strait of Gibraltar, shares a 1.2 kilometres (3⁄4 mi) land border with the Andalusian province of Cádiz.

Cádiz is a province of southern Spain, in the southwestern part of the autonomous community of Andalusia. It is the southernmost part of mainland Spain, as well as the southernmost part of continental Europe.

It is bordered by the Spanish provinces of Huelva, Seville, and Málaga, as well as the Atlantic Ocean, the Mediterranean Sea, the Strait of Gibraltar and the British overseas territory of Gibraltar. Its area is 7,385 square kilometres (2,851 sq mi).

The province of Badajoz (Spanish: provincia de Badajoz [baðaˈxoθ] ; Portuguese: província de Badajoz [bɐðɐˈʒɔʃ]) is a province of western Spain located in the autonomous community of Extremadura. It was formed in 1833. It is bordered by the provinces of Cáceres in the north, Toledo, Ciudad Real in the east, Córdoba in the south-east, Seville, and Huelva in the south and Portugal in the west.

With an area of 21,766 km (8,404 sq mi), it is the largest province in Spain. The other province of Extremadura, Cáceres, is the second largest with 19,868 km in area. The province has a relatively lower population density in comparison to other provinces in Spain.

Huelva is a province in the autonomous community of Andalusia, Spain. The province is divided into 79 municipalities. As of the 2024 Spanish census, Huelva is the 29th most populous of Spain's 50 provinces, with 535,734 inhabitants, and the 25th largest by land area, spanning 10,127.43 square kilometres (3,910.22 sq mi). Municipalities are the most basic local political division in Spain and can only belong to one province. They enjoy a large degree of autonomy in their local administration, being in charge of tasks such as urban planning, water supply, lighting, roads, local police, and firefighting.

The organisation of municipalities in Spain is outlined by the local government law Ley 7/1985, de 2 de abril, Reguladora de las Bases del Régimen Local (transl. Law 7/1985, of 2 April, Regulating the Bases of the Local Administration), which was passed by the Cortes Generales—Spain’s national parliament—on 2 April 1985 and finalised by royal decree on 18 April 1986. Municipalities in Huelva are also governed by the Statute of Autonomy of Andalusia, which includes provisions concerning their relations with Andalusia's autonomous government. All citizens of Spain are required to register in the municipality in which they reside. Each municipality is a corporation with independent legal personhood: its governing body is called the ayuntamiento (municipal council or corporation), a term often also used to refer to the municipal offices (city and town halls). The ayuntamiento is composed of the mayor (Spanish: alcalde), the deputy mayors (tenientes de alcalde) and the councillors (concejales), who form the plenary (pleno), the deliberative body. Municipalities are categorised by population for determining the number of councillors: three when the population is up to 100 inhabitants, five for 101–250, seven for 251–1,000, nine for 1,001–2,000, eleven for 2,001–5,000, thirteen for 5,001–10,000, seventeen for 10,001–20,000, twenty-one for 20,001–50,000, and twenty-five for 50,001–100,000. One councillor is added for every additional 100,000 inhabitants, with a further one included if the total would otherwise be even, to avoid tied votes.
