Overlooking the lake, Ledro, in the province of Trento, was officially founded in 2010 and is the union of six existing municipalities (Pieve di Ledro, Bezzecca, Concei, Molina di Ledro, Tiarno di Sopra e Tiarno di Sotto), which once all belonged to the Union of the Municipalities of the Ledro Valley. It is located along the border with Lombardy, between the foothills of the mountain ranges of the Catione, to the South and of Cadria to the North.
Even though embellished by particular historical moments, these six municipalities have always been united by a single historical and political evolution, that led them to be known, over the centuries, with the following names: "Alutraenses" (by Pliny, in reference to the fact that the populations lived between the mighty wings of the Giudicarle and the Garda areas), "Plebs Leutri" (the People of Ledro), "Res Publica Leudri", "Comunitas Leudri", "General Municipality of Ledro".
The valley has been inhabited since ancient times, by different populations: the Ligurians, the Nordalpini, the Gauls, the Euganei and the Venetians. The Romans, after conquering the area, colonized the area and created a rural municipium. After the fall of the Roman Empire succeeded the Lombards who, during their two centuries of domination, contributed to further amalgamate the people who lived in the Valle di Ledro. In 1004 the County of Trentino became part the Holy Roman Empire and, in 1027, Emperor Conrad II granted it to Bishop Uldarico II. Since then, the bishop of Trento preserves the title of Prince of the Holy Roman Empire and, at the time, influenced a spiritual and temporal power over the whole territory. After a particularly dark and ominous century (the XVII century), with its plagues and famines, the XVIII century, thanks to the rule of Maria Theresa of Austria, the territories experienced a particularly happy period, especially from the economic point of view. After the Napoleonic period, in 1813, the lands returned to the Habsburgs and remain under their domain, until the end of World War I, when it was incorporated into the Kingdom of Italy.
