The region of Silves has been inhabited since the
Palaeolithic, as attested by archaeological remains, including several
menhirs. The
river Arade, which was navigable in historical times, linked the hinterland to the open ocean and allowed the transport of produce and commerce. The town of Silves (
Cilpes) was possibly founded during the times of
Roman domination, when the region was part of the
Lusitania province. It was probably a
Lusitanian Castro in pre-Roman times; however, the region was also settled by other Indo-European tribes, such as the
Celtici and
Cynetes. Silves was once also part of the
Visigothic Kingdom (418–c. 721). After 713, when
the Moors invaded Iberia, Silves became part of the Umayyad
Emirate of Córdoba under the Arabic name of
Shilb (شلب). In the 10th century it was one of the most important towns in western
Al-Andalus. Silves became an
independent taifa in 1027 under the rule of Ibn Mozaine and his son, who was dethroned in 1051 by al-Mu'tadid, the governor of
Seville.
Al-Mu'tamid ibn Abbad, the son of al-Mu'tadid and a famous poet, ruled the taifa of Silves until 1091. After the
Almoravid conquest the town became
Almohad in 1156. In 1189, King
Sancho I of Portugal conquered the town with the aid of Northern European crusaders. Sancho ordered the fortification of the city and built a castle, which is today an important monument of Portuguese heritage. At the time he also styled himself "By the Grace of God, King of Portugal and Silves (
Dei Gratiæ, Rex Portugalliæ et Silbis). However, he soon lost the town again to the Almohads after
sieges in 1190 and 1191. Periodic raiding expeditions were sent from
Al-Andalus to ravage the Iberian Christian kingdoms, bringing back booty and slaves. The governor of
Córdoba attacked Silves in 1191, and took 3,000 Christian slaves. In 1197, the city was
attacked by German crusaders, but did not permanently change hands. The town was finally taken from the last Muslim king Ibn Afan by
Paio Peres Correia, Grand-Master of the
Order of Santiago in 1242, after the
Alentejo and most of the coast had already fallen in 1238. The great
mosque was changed into
Silves Cathedral (
Sé Catedral). Silves declined in importance thereafter and was eclipsed in the region by
Faro during the
colonial period. In 1491, the town of Silves was given to queen
Eleanora by her husband, king
John II of Portugal. National Breeding Center in Silves municipality. In the 19th century, Silves became an important centre for the Portuguese
cork industry. The industry's decline began after cork factory workers, instigated by
communist and
anarcho-syndicalist organizations resorting to coercion at gunpoint, supported the failed
Portuguese general strike of 1934, after which the authoritarian
Estado Novo regime retaliated by effectively closing down the industry in the town. ==Sights==
