Trentino-Alto Adige is an autonomous region in Northern Italy. Since the 1970s, most legislative and administrative powers have been transferred to the two self-governing provinces that make up the region: Trentino and South Tyrol. From the 8th century until its annexation by Italy in 1919, the region was part of Austria-Hungary and its predecessors, the Austrian Empireand the Holy Roman Empire. Together with the Austrian state of Tyrol it is represented by the Euroregion Tyrol-South Tyrol-Trentino. With a past of poverty, the region is today among the wealthiest and most developed in both Italy and the whole European Union.
