The earliest reference to the three Counts of Tyrol appears in the archives about the year 1140, and we find the family dwelling in the Castle Tyrol or Teriolis, near Meran. It was from this fortress, now in a ruinous condition except for the chapel and fine porch dating from the twelfth century, that not only the family took its name but eventually the whole country came to be known. Gradually one by one the possessions of the other nobles in Tyrol were taken from them or became absorbed by marriage in that of the Counts of Tyrol. Until about 1240 the then reigning Count Albert was able to style himself Prince Count (or gefürsteter Graf) of Tyrol so widespread and rich were his possessions. The Principality thus formed remained a fief of the German Empire until the reign of Maximilian I. (1493) when it was incorporated with the other possessions of the Crown. The first of the Prince Counts of Tyrol was successful, in 1248, in obtaining from the Counts of Andechs the district of the Inn Valley, once the site of Roman Veldidena, which place tradition asserts was destroyed about A.D. 452 by the Huns under the leadership of Attila on their return through Tyrol after their defeat by Aëtius at the battle of Chalons. During the early Middle Ages the Premonstratensian Abbey of Wilten had been built on the site of the ancient town, and later on the Counts of Andechs, who had become possessed of land in the neighbourhood on the banks of the Inn, became the most powerful and influential nobles in the district. Under them a trading post or centre of commerce was founded near the bridge over the Inn, the importance of which can be easily understood when its proximity to the Brenner high-road, a then busy thoroughfare, is borne in mind. From this bridge over the Inn was derived the name of the town Innsbruck--afterwards destined to become the capital of Tyrol--a mention of which appears for the first time in archives of the year 1327. It was to the foresight and enterprise of Otto of Andechs that the town owed the walls, towers, and fortifications which were to stand it in good stead. Count Otto also built himself a palace, which still is known as Ottoburg.
