From the Arabic maǧrà. A Mozarabic variant of the Latin matrix, matricis. Although the site of modern-day Madrid has been occupied since prehistoric times, there are archaeological remains of Carpetani settlement, Roman villas, a Visigoth basilica near the church of Santa María de la Almudena and three Visigoth necropoleis near Casa de Campo, Tetúan and Vicálvaro, the first historical document about the existence of an established settlement in Madrid dates from the Muslim age. At the second half of the 9th century, Emir Muhammad I of Córdoba built a fortress on a headland near the river Manzanares, as one of the many fortresses he ordered to be built on the border between Al-Andalus and the kingdoms of León and Castile, with the objective of protecting Toledo from the Christian invasions and as a starting point for Muslim offensives. After the disintegration of the Caliphate of Córdoba, Madrid was integrated in the Taifa of Toledo. With the surrender of Toledo to Alfonso VI of León and Castile, the city was conquered by Christians in 1085, it was integrated into the kingdom of Castile as a property of the Crown.
Christians replaced Muslims in the occupation of the centre of the city, while Muslims and Jews settled in the suburbs. The city was thriving and was given the title of Villa, whose administrative district extended from the Jarama in the east to the river Guadarrama in the west; the government of the town was vested to the neighbouring of Madrid since 1346, when king Alfonso XI of Castile implements the regiment, for which only the local oligarchy was taking sides in city decisions. Since 1188, Madrid won the right to be a city with representation in the courts of Castile. In 1202, King Alfonso VIII of Castile gave Madrid its first charter to regulate the municipal council, expanded in 1222 by Ferdinand III of Castile. In 1309, the Courts of Castile were joined in Madrid for the first time under Ferdinand IV of Castile, in 1329, 1339, 1391, 1393, 1419 and twice in 1435. Since the unification of the kingdoms of Spain under a common Crown, the Courts were convened in Madrid more often. During the revolt of the Comuneros, led by Juan de Padilla, Madrid joined the revolt against Emperor Charles V of Germany and I of Spain, but after defeat at the Battle of Villalar, Madrid was besieged and occupied by the royal troops.
However, Charles I gave it the titles of Coronada and Imperial. When Francis I of France was captured at the battle of Pavia, he was imprisoned in Madrid, and in the village is dated the Treaty of Madrid of 1526. Is seen in the foreground the banks of the Manzanare
Acanthobdella peledina is a species of leech in the infraclass Acanthobdellidea. It feeds on the skin and blood of freshwater fishes in the boreal regions of northern Europe and North America. Leaches in this infraclass are primitive, some authors place them in a separate subclass to the Hirudinea. However, the World Register of Marine Species places them within the Hirudinea, as a sister group to Euhirudinea, the true leeches. Acanthobdella peledina was first described by the German zoologist Adolph Eduard Grube in 1851. For a long time, it was believed to be the only species in the infraclass, but in 1966, another species in the genus, A. livanowi, was described from the vicinity of the Kamchatka Peninsula in eastern Siberia. A. peledina differs from other fish leeches in not having a sucker at its anterior end. It is in fact unique among leeches in having chaetae at all, in having a coelom divided by septa into a discontinuous channel. Other ways in which it differs from other leeches are that the body is divided into 29 segments, it lacks a prostomium and a peristomium, the nephridia do not have funnels.
It has a sucker at the posterior end, moves in a typical leech fashion by alternately extending its anterior end forward clinging on with its hooked chaetae while it brings its posterior sucker close to its front end. The leeches are olive green and about 23 mm in length; the species has a boreal distribution and is known from freshwater locations in northern Europe and Asia, from Alaska. One of the fish in Alaska parasitized by A. peledina is the sardine cisco. The leeches were found just behind the pelvic fins with their anterior ends embedded in the skin and muscle tissue below

The ribbon consisted of five equal stripes, white, white, identical to the Independence Decoration. Over 150 awards of the Independence Commemorative Decoration were made between 1970 and 1978. Most recipients were political supporters or allies of the Rhodesian Front government of Ian Douglas Smith. Recipients included the ZUPO leader Jeremiah Chirau, the Rhodesian High Commissioner in London, Andrew Skeen.
The last recipient of the Independence Commemorative Decoration was the sanctions-buster Jack Malloch, owner of air transport company Affretair, in 1978.
