Tomar, also known in English as Thomar, is a city of some 20,000 in Portugal. It is located in Tomar Municipality, that has a total area of 351.0 km² and a total population of 40,674 (2011) inhabitants.
The municipality is composed of 16 parishes, and is located in Santarém District.
The town of Tomar was born inside the walls of the Convento de Cristo, constructed under the orders of Gualdim de Pais, the fourth grand master of the Knights Templar in the late 12th century.
Tomar is one of Portugal's historical jewels and more significantly was the last Templar town to be commissioned for construction. Tomar was especially important in the 15th century when it was a centre of Portuguese overseas expansion under Henry the Navigator, the Grand Master of the Order of Christ, successor organization to the Templars in Portugal.
Under the modern city lies the Roman city of Sellium. After the conquest of the region from the Moors in the Portuguese Reconquista, the land was granted in 1159 as a fief to the Order of the Knights Templar. Its Grand Master in Portugal, and Tomar's somewhat mythical founder, Gualdim Pais, laid in 1160 the first stone of the Castle and Monastery that would become the Head-Quarters of the Order in Portugal. The foral or feudal contract was granted in 1162 by the Grand Master to the people. The Templars ruled from Tomar a vast region of central Portugal which they pledged to defend from Moorish attacks and raids. Like many lords of the unpopulated former frontier region of central Portugal, the villagers were given relatively liberal conditions in comparison with those of the northern regions of Portugal, in order to attract new immigrants. Those inhabitants who could sustain a horse were obliged to pay military service in return for privileges. They were not allowed the title of Knight which was reserved to the monks. Women were also admitted to the Order, although they didn't fight.
In 1190 Abu Yusuf al-Mansur, a Moroccan caliph, and his army attacked Tomar. However the crusader Knights and their 72-year-old leader kept them at bay. A plaque commemorates this bloody battle at the Porta da Sangue at the Castelo Templário (Castle of Tomar).
Henry the Navigator was made the Governor of the Order, and it is believed that he used the resources and knowledge of the Order to succeed in his enterprises in Africa and in the Atlantic. The cross of the Order of Christ that was painted in the sails of the caravels that crossed the seas, and the Catholic missions in the new lands were under the authority of the Tomar clerics until 1514. Henry, enriched by his overseas enterprises, was the first ruler to ameliorate the buildings of the Convento de Cristo since its construction by Gualdim Pais. He also ordered dams to be built to control the river Nabão and swamps to be drained. This allowed the burgeoning town to attract more settlers. Henry ordered the new streets to be designed in a rational, geometrical fashion, as they can still be seen today.
In the reign of Manuel I of Portugal the convent took its final form within the Manueline renaissance style. With the growing importance of the town as master of Portugal's overseas empire, the leadership of the Order was granted to the King by the Pope.
However, under pressure from the Monarchs of Spain, the King soon proclaimed by Edict that all the Jews remaining within the territory of Portugal would be after a short period considered Christians, although simultaneously he forbade them to leave, fearing that the exodus of Jewish men of knowledge and capital would harm Portugal's burgeoning commercial empire. Jews were largely undisturbed as nominal Christians for several decades, until the establishment of a Tribunal of the Portuguese Inquisition by the initiative of the Catholic Clergy in the town. Under persecution, wealthier Jews fled, most others were forced to convert. Hundreds of both Jews and New Christians were arrested, tortured and burned at the stake in autos da fé, in a frenzy of persecution that peaked around 1550. Many others were expropriated of their property. Jewish ascendancy, more than Jewish religion, together with personal wealth determined whom would be persecuted, since the expropriations reverted to the institution of the Inquisition itself. The town lost then with the persecution of its merchants and professionals most of its relevance as a trading centre. New Christian names among the inhabitants are very common today.
During the 18th century Tomar was one of the first regions of Portugal in industry. In the reign of Maria I, with royal support, a textile factory of Jácome Ratton was established against the opposition of the Order. The hydraulic resources of the river Nabão were used to supply energy to this and many other factories, namely paper factories, foundries, glassworks, silks and soaps.
In 1834 all the religious orders, including the Order of Christ, were disbanded.
