History of Latvia between 1150 - 1206
At the end of the 12th century, Latvia was more often visited by traders from Western Europe who set out on trading journeys along Latvia's longest river, the Daugava, to Russia. At the very end of the 12th century, German traders arrived and with them came preachers of the Christian faith who attempted to convert the pagan Baltic and Finno-Ugric tribes to the Christian faith. The Livs did not willingly convert to the new and different beliefs and practices, and particularly opposed the ritual of baptism. News of this reached the Pope in Rome and it was decided that Crusaders would be sent into Latvia to influence the situation.
The Germans founded Riga in 1201, and gradually it became the largest city in the Southern part of the Baltic Sea. Order of the Sword Brothers was founded in 1202 to subjugate the local people. The Livs were conquered by 1207 and the most of Latgalians by 1214.

Previous historical period: Viking Age (800-1149) | Next historical period: State of the Teutonic Order (1207-1561)Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
