Arco family

The House of Arco is the name of an ancient noble family, originally from Arco, in Northern Italy. Members of the family played important roles within the Holy Roman Empire, Austro-Hungarian Empire and Italy.

History
They were first attested to in 1124 and were recognized as free nobles in 1186. For many centuries, they held the Castle of Arco. In 1413, they became Imperial counts. In the 17th century, members of the family moved from Arco to Bavaria, Mantua, Salzburg, and Silesia. At the beginning of the 19th century, Bavarian branch split into three cadet lines: Arco auf Valley, Arco-Stepperg and Arco-Zinneberg. The family is still extant, primarily in Bavaria, but the Castle of Arco, which has been in the possession of the branch in Mantua has belonged to the municipality of Arco since 1982.
