Strait of Gibraltar in the context of "Strait"

The Mediterranean Sea (/ˌmɛdɪtəˈreɪniən/ MED-ih-tə-RAY-nee-ən) is an intercontinental sea situated between Europe, Asia, and Africa. It is surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, and on the south by North Africa. To its west it is connected to the Atlantic Ocean via the Strait of Gibraltar that separates the Iberian Peninsula in Europe from Morocco in Africa by only 14 km (9 mi); additionally, it is connected to the Black Sea through the Bosporus strait that intersects Turkey in the northeast and the Red Sea via the Suez Canal in the southeast.

The Mediterranean Sea covers an area of about 2,500,000 km (970,000 sq mi), representing 0.7% of the global ocean surface; it includes fifteen marginal seas, including the Aegean, Adriatic, Tyrrhenian, and Marmara. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago.

The olive (botanical name Olea europaea, "European olive") is a species of subtropical evergreen tree in the family Oleaceae. Originating in Asia Minor, it is abundant throughout the Mediterranean Basin, with wild subspecies in Africa and western Asia; modern cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. The olive is the type species for its genus, Olea, and lends its name to the Oleaceae plant family, which includes lilac, jasmine, forsythia, and ash. The olive fruit is classed botanically as a drupe, similar in structure and function to the cherry or peach. The term oil—now used to describe any viscous water-insoluble liquid—was originally synonymous with olive oil, the liquid fat derived from olives.

The olive has deep historical, economic, and cultural significance in the Mediterranean. It is among the oldest fruit trees domesticated by humans, being first cultivated in the Eastern Mediterranean between 6,000 and 4,000 BC, most likely in the Levant. The olive gradually disseminated throughout the Mediterranean via trade and human migration starting in the 16th century BC; it took root in Crete around 3500 BC and reached Iberia by about 1050 BC. Olive cultivation was vital to the growth and prosperity of various Mediterranean civilizations, from the Minoans and Myceneans of the Bronze Age to the Greeks and Romans of classical antiquity.

The Messinian salinity crisis (also referred to as the Messinian event, and in its latest stage as the Lago Mare event) was an event in which the Mediterranean Sea went into a cycle of partial or nearly complete desiccation (drying-up) throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago). It ended with the Zanclean flood, when the Atlantic reclaimed the basin.

Sediment samples from below the deep seafloor of the Mediterranean Sea, which include evaporite minerals, soils, and fossil plants, show that the precursor of the Strait of Gibraltar closed about 5.96 million years ago, sealing the Mediterranean off from the Atlantic. This resulted in a period of partial desiccation of the Mediterranean Sea, the first of several such periods during the late Miocene. After the strait closed for the last time around 5.6 Ma, the region's generally dry climate at the time dried the Mediterranean basin out nearly completely within a thousand years. This massive desiccation left a deep dry basin, reaching 3 to 5 km (1.9 to 3.1 mi) deep below normal sea level, with a few hypersaline pockets similar to today's Dead Sea. Then, around 5.5 Ma, wetter climatic conditions resulted in the basin receiving more fresh water from rivers, progressively filling and diluting the hypersaline lakes into larger pockets of brackish water (much like today's Caspian Sea). The Messinian salinity crisis ended with the Strait of Gibraltar finally reopening 5.33 Ma, when the Atlantic rapidly filled up the Mediterranean basin in what is known as the Zanclean flood.

The Zanclean flood or Zanclean deluge is theorized to have refilled the Mediterranean Sea 5.33 million years ago.This flooding ended the Messinian salinity crisis and reconnected the Mediterranean Sea to the Atlantic Ocean, although it is possible that even before the flood there were partial connections to the Atlantic Ocean. The re-connection marks the beginning of the Zanclean age, the name given to the earliest age on the geologic time scale of the Pliocene.

According to this model, water from the Atlantic Ocean refilled the dried-up basin through the modern-day Strait of Gibraltar. Ninety percent of the Mediterranean Basin flooding occurred abruptly during a period estimated to have been between several months and two years, following low water discharges that could have lasted for several thousand years. Sea level rise in the basin may at times have reached rates greater than 10 metres per day (5 fathom/d; 30 ft/d). Based on the erosion features preserved until modern times under the Pliocene sediment, Garcia-Castellanos et al. estimate that water rushed down a drop of more than 1,000 metres (3,300 ft) with a maximum discharge of about 100 million cubic metres per second (3.5 billion cubic feet per second), three orders of magnitude larger than the present-day Amazon River. Studies of the underground structures at the Strait of Gibraltar show that the flooding channel descended gradually toward the bottom of the basin rather than forming a steep waterfall.

Ceuta (UK: /ˈsjuːtə/, US: /ˈseɪuːtə/, Spanish: [ˈθewta, ˈsewta] ; Moroccan Arabic: سَبْتَة, romanized: Sabtah) is an autonomous city of Spain on the North African coast. Bordered by Morocco, it lies along the boundary between the Mediterranean Sea and the Atlantic Ocean. Ceuta is one of the special member state territories of the European Union.

Phoenicians founded a settlement in the peninsula of Almina, which had continuity under Roman and Byzantine rule (Septem Fratres). It was annexed to the early Arab Caliphates upon the Islamic conquest of the Maghreb, only to be destroyed during the Berber Revolt. It was rebuilt in the 9th century by Majkasa Ghomaras, and for much of the middle ages, regional powers north and south of the Strait of Gibraltar vied for control over Ceuta, which was a key contested port in the so-called Battle of the Strait. In 1415, it was annexed to the Kingdom of Portugal, and subsequently, after 1580, to the Hispanic Monarchy, with the city choosing to stay in the latter after 1640. Ceuta was a regular municipality belonging to the Spanish province of Cádiz prior to the passing of its Statute of Autonomy in March 1995, as provided by the Spanish Constitution, henceforth becoming an autonomous city.

Gibraltar (/dʒɪˈbrɔːltər/ jih-BRAWL-tər, Spanish: [xiβɾalˈtaɾ]) is a British Overseas Territory and city located at the southern tip of the Iberian Peninsula, on the Bay of Gibraltar, near the exit of the Mediterranean Sea into the Atlantic Ocean (Strait of Gibraltar). It has an area of 6.8 km (2.6 sq mi) and is bordered to the north by Spain (Campo de Gibraltar). The landscape is dominated by the Rock of Gibraltar, at the foot of which is a densely populated town area. Gibraltar is home to around 34,000 people, primarily Gibraltarians.

Gibraltar was founded as a permanent watchtower by the Almohads in 1160. It switched control between the Nasrids, Castilians and Marinids in the Late Middle Ages, acquiring larger strategic clout upon the destruction of nearby Algeciras c. 1375. It became again part of the Crown of Castile in 1462. In 1704, Anglo-Dutch forces captured Gibraltar from Spain during the War of the Spanish Succession, and it was ceded to Great Britain in perpetuity under the Treaty of Utrecht in 1713. It became an important base for the Royal Navy, particularly during the Napoleonic Wars and World War II, as it controlled the narrow entrance and exit to the Mediterranean Sea, the Strait of Gibraltar, with half the world's seaborne trade passing through it.

The phenomenon of colonization is one that has occurred around the globe and across time. Various ancient and medieval polities established colonies – such as the Phoenicians, Babylonians, Persians, Greeks, Romans, Han Chinese, and Arabs. The High Middle Ages saw colonising Europeans moving west, north, east and south. The medieval Crusader states in the Levant exemplify some colonial features similar to those of colonies in the ancient world.

A new phase of European colonialism began with the "Age of Discovery", led by the Portuguese, who became increasingly expansionist following the conquest of Ceuta in 1415. Portugal aimed to control navigation through the Strait of Gibraltar, to spread Christianity, to amass wealth and plunder, and to suppress predation on Portuguese populations by Barbary pirates (who operated as part of a longstanding African slave tradeat that point a minor trade, one the Portuguese would soon reverse and surpass). Around 1450 the Portuguese developed a lighter ship, the caravel based on North African fishing boats. Caravels could sail further and faster than previous vessels, were highly maneuverable, and could sail into the wind.
