Reus (Catalan pronunciation: [ˈrɛws]) is the capital of Baix Camp, in Camp de Tarragona, Catalonia, Spain. The area has always been an important producer of wines and spirits, and gained continental importance at the time of the Phylloxera plague. Currently it is known for its commercial activity, for being a centre for rock-climbing and as the birthplace of architect Antoni Gaudí.

The origin of the name is a source of discussion. One of the theories is that Reus comes from the Latin word used to describe convict prisoners (reus), and as such, it would be a Roman penitentiary. Currently, the most accepted theory is that the name has Celtic roots, from the root red that originated the name redis (or reddis), that would approximately mean place in the way / place in the roads, or said alternatively, an inhabited place in a cross-road.

Around 1150 Robert d'Aguiló repopulated the region of Reus, after receiving it on 3 June 1154. On 5 June 1154 the archbishop of Tarragona gave two-thirds of Reus to Bertran de Castellet, as a castellan, with the order to build a church. On 29 June 1159, the distribution of income from ecclesiastical goods, the third of its Reus parish of Santa Maria was awarded to the camerlengo, starting the duplicity of governing the town. The camerlengo has the third of Reus parish. At this time the city was known as Redis or Reddis. The castellan Bernat de Bell-lloc gave the title of town to Reus on 3 August 1183, giving the ownership of houses and gardens, establishing a census to pay for farmland and reserving justice, but recognizing its vassalage towards the archbishopric of Tarragona. On 2 June 1186 the camerlengo Joan de Santboi confirmed the rights given by the castellan Bernard de Bell-lloc.

In 1305 Reus revolted against the Archbishop Rodrigo Tello, who wanted the citizens of Reus to pay for rebuilding the walls of Tarragona. In 1309 the king of Aragon gave Reus the right to hold a market on Mondays. The dynasty of Bell-lloc castellans became extinct in 1327 and then Bernard de Cabrera became the new castellan, but in 1335 the castellan was sold to Pere Mulet, who lost it on 1345. Pere Mulet heirs sold their rights to Bernat d'Olzinelles in 1349. The camerlengo Pere Roger de Belfort disputed domain to the Archbishop López de Ayerbe, who sent an army that decimated the town. A second attack was repulsed. A third attack was led by military occupation of the town and Reus was sacked. The camerlengo Pere Roger de Belfort, nephew of Pope Clement VI, who was living in Avignon with his uncle, persuaded the Pope to call the archbishop of Tarragona and the Pope received a commitment for peace. Pere Roger de Belfort gave the roses off his coat to coat of arms of the town and he later became Pope Gregory XI, he retained the title as a camerlengo of Reus, so the coat of arms was crowned and adorned with, a papal tiara and the keys of St. Peter.

At the beginning of the Catalan Revolt war the town had 1200 houses, but reduced to 800 by the end of the war. On 16 December 1640 was declared an enemy of the fatherland by the Parliament and confiscated the goods of the inhabitants, as a response to the inactive participation in the war. In 1641 it was occupied by the French general La Mothe.

Reus was loyal to Philip V until 1705, but this year, under the direction of Joan Nebot, revolted in favor of the Archduke Charles. On 3 July 1706 the Archduke Charles came to the town. In 1707 fell shortly to the Bourbons, but in 1709 Reus surrendered to the Spanish and French Bourbons. In 1710 Reus returned again to the field of Archduke Charles. On 5 June 1712 the wife of the Archduke, Elisabeth Christine, gave the title of imperial city to Reus. In 1713 Reus was occupied finally by the Bourbon.

In the eighteenth century Reus had phenomenal growth and became the second city of the principality of Catalonia. The walls were completely demolished in 1766. The town developed the textile trade and the liquor trade. In this last contribution was the first center, the others were London and Paris. From this time it's the popular sentence "Reus, Paris and London”, because Reus was one of the centers of the liquor marquet. The construction of a canal between Reus and Salou, proposed by Pere Sunyer was granted in 1805, but it was stopped because of the French War. At this time Reus had consulates in the United States, Liguria, England, Holland, Sweden, Ragusa, Denmark, Sicily, the Papal States, France, Portugal, Naples and Prussia.

In 1854 the Reus Gas Company was founded. In 1856 the railway between Reus and Tarragona was built. In 1884 the Catalan Association of Reus was founded and in 1893 was celebrated the Assembly of the Unió Catalana. In 1886 Pau Font de Rubinat founded the Catalan newspaper Lo Somatent. In 1895 the phylloxera killed big areas of vineyards in the region of Reus and many of this areas were changed to hazelnuts.

In 1931 Reus voted for the republic. In 1936 Francisco Franco bombed the city until his rebel army occupied the city on 15 January 1939, starting with the dictatorship of Franco until his death in 1975.

The first democratic mayor after Franco was Carles Martí Massagué, lawyer of Reus. In 1983 Anton Borrell Marcó was the new mayor of the city, but he died in a car accident on the road from Reus to Cambrils, then his successor was Juan Maria Roig. After him, Josep Abelló Padró was the mayor until 1999, replaced by Lluís Miquel Pérez Segura, who occupied the position until 2011, when the current mayor, Carles Pellicer i Punyed, started.

Reus was for long the second city of Catalonia with a population of 14,440 in 1787 and 27,257 in 1860. It was overtaken by Tarragona and Lleida between 1900 and 1930. The population barely grew between 1920 and 1930, with 30,266 and 35,950 inhabitants, respectively. From then, the population growth has been substantial, from 41,014 inhabitants in 1960 to 108,100 inhabitants that the city has as of the end of 2008. Immigration, mostly from Marrakesh, has been a portion of that increase. About 6% are Muslim and 8% from other religions.

The principal Reus festivity is Sant Pere on 29 June, declared of National Touristic Interest. One of the most characteristic and popular acts of these festivities is the so-called tronada, which is a series of 29 little mortars masclets with bangers interleaved, arranged linearly around the Mercadal square (where the city hall is located), united by a hand craft gunpowder line. This line ends in a square shape in front of the city hall, with more bangers and 9 more masclets. Also, on September 25, the Mare de Déu de la Misericòrdia is held.

Other noteworthy festivities are the Carnival and the Anada a l'Antiga towards Salou. Most of the neighborhoods have their own festivities.

This bi-annual exhibition features fine art photographers from around the world working in Alternative Photographic Processes (such as Platinum Printing, Gum Dichromate, Etc.). At each Biennal they award the Medalla Gaudi award to a select few artists and purchase their work for the Institut Municipal d’Accio Cultural's permanent collection.

The first flag of Reus was in use from 1774 to 1943. The flag was dark red with the city arms in the centre.

In 1943 the flag was changed because the color red seemed to be associated with the left, defeated in the civil war (1936–39). As the historic city arms were argent with a heraldic rose the new flag was white with a heraldic rose in the center. Minor changes to the rose in the flag were made after 1943.

Currently the rose has a new version, taken from the city emblem. The emblem itself has official status. This presumably also applies to the flag, but this has not been confirmed by the local government.
