Piedmont in the context of "Valenza Po"

The Duchy of Milan (Italian: Ducato di Milano; Lombard: Ducaa de Milan) was a state in Northern Italy, created in 1395 by Gian Galeazzo Visconti, then the lord of Milan, and a member of the important Visconti family, which had been ruling the city since 1277. At that time, it included twenty-six towns and the wide rural area of the middle Padan Plain east of the hills of Montferrat. During much of its existence, it was wedged between Savoy to the west, Republic of Venice to the east, the Swiss Confederacy to the north, and separated from the Mediterranean by the Republic of Genoa to the south. The duchy was at its largest at the beginning of the 15th century, at which time it included almost all of what is now Lombardy and parts of what are now Piedmont, Veneto, Tuscany, and Emilia-Romagna.

Under the House of Sforza, Milan experienced a period of great prosperity with the introduction of the silk industry, becoming one of the wealthiest states during the Renaissance. From the late 15th century, the Duchy of Milan was contested between the forces of the Habsburg Monarchy and the Kingdom of France. It was ruled by Habsburg Spain from 1556 and it passed to Habsburg Austria in 1707 during the War of the Spanish Succession. The duchy remained an Austrian possession until 1796 when a French army under Napoleon Bonaparte conquered it, and it ceased to exist a year later as a result of the Treaty of Campo Formio, when Austria ceded it to the new Cisalpine Republic.

Northern Italy (Italian: Italia Settentrionale, Nord Italia, Alta Italia) is a geographical and cultural region in the northern part of Italy. The Italian National Institute of Statistics defines the region as encompassing the four northwestern regions of Piedmont, Aosta Valley, Liguria and Lombardy in addition to the four northeastern regions of Trentino-Alto Adige/Südtirol, Veneto, Friuli-Venezia Giulia and Emilia-Romagna.

With a population of 27.5 million in an area of 120,312.72 km (46,453.00 sq mi) as of 2025, the region covers roughly 40% of Italy and contains 46% of its population. Two of Italy's largest metropolitan areas, Milan and Turin, are located in the region. Northern Italy's GDP was estimated at €1 trillion in 2021, accounting for 56.5% of the Italian economy.

The Ligures (Latin sg. Ligus; also Ligustici or Ligustini) or in English Ligurians, were an ancient people after whom Liguria, a region of present-day north-western Italy, is named. Because of the strong Celtic influences on their language and culture, they were also known in antiquity as Celto-Ligures and hence in English as Celto-Ligurians.

In pre-Roman times, the Ligurians occupied the present-day Italian region of Liguria, Piedmont, northern Tuscany, western Lombardy, western Emilia-Romagna, and northern Sardinia, reaching also Elba and Sicily. They inhabited also the French region of Provence-Alpes-Côte d'Azur and Corsica; however, it is generally believed that around 2000 BC the Ligurians occupied a much larger area, extending as far as what is today Catalonia (in the north-eastern corner of the Iberian Peninsula).

Turin (/tjʊəˈrɪn, ˈtjʊərɪn/ ture-IN, TURE-in, Piedmontese: [tyˈriŋ] ; Italian: Torino [toˈriːno] ; Latin: Augusta Taurinorum, then Taurinum) is a city and an important business and cultural centre in northern Italy. It is the capital city of the Piedmont region and of the Metropolitan City of Turin. From 1861 to 1865, it was the first capital of the Kingdom of Italy. The city is mainly on the western bank of the River Po, below its Susa Valley, and is surrounded by the western Alpine arch and Superga hill. The population of the city proper is 856,745 as of 2025, while the population of the urban area is estimated by Eurostat to be 1.7 million inhabitants. The Turin metropolitan area is estimated by the OECD to have a population of 2.2 million.

The city was historically a major European political centre. From 1563, it was the capital of the Duchy of Savoy, then of the Kingdom of Sardinia ruled by the House of Savoy, and the first capital of the Kingdom of Italy from 1861 to 1865. Turin is sometimes called "the cradle of Italian liberty" for having been the political and intellectual centre of the Risorgimento that led to the unification of Italy, as well as the birthplace of notable individuals who contributed to it, such as Camillo Benso, Count of Cavour.

Lombardy (Lombard and Italian: Lombardia; Romansh: Lumbardia) is an administrative region of Italy that covers 23,844 km (9,206 sq mi); it is located in northern Italy and has a population of about 10 million people, constituting more than one-sixth of Italy's population. Lombardy is located between the Alps mountain range and tributaries of the river Po, and includes Milan, its capital, the largest metropolitan area in the country, and among the largest in the EU.

Its territory is divided into 1,502 comuni (the region with the largest number of comuni in the entire national territory), distributed among 12 administrative subdivisions (11 provinces plus the Metropolitan City of Milan). The region ranks first in Italy in terms of population, population density, and number of local authorities, while it is fourth in terms of surface area, after Sicily, Piedmont, and Sardinia.

The term Kingdom of Sardinia denotes the Savoyard state from 1720 to 1861. From 1720 to 1847, only the island of Sardinia proper was part of the Kingdom of Sardinia, while the other mainland possessions (principally the Duchy of Savoy, Principality of Piedmont, County of Nice, Duchy of Genoa, and others) were held by the House of Savoy in their own right, hence forming a composite monarchy and a personal union, which was formally referred to as the "States of His Majesty the King of Sardinia". This situation was changed by the Perfect Fusion act of 1847, which created a unitary kingdom. Regardless, historians often use "Sardinia" as a synecdoche to designate the whole Savoyard state from 1720. Due to the fact that Piedmont was the seat of power and prominent part of the entity, the state is also referred to as Sardinia–Piedmont or Piedmont–Sardinia, and sometimes erroneously as the Kingdom of Piedmont.

Before becoming a possession of the House of Savoy, the medieval Kingdom of Sardinia had been part of the Crown of Aragon and then of the burgeoning Spanish Empire. With the Treaty of The Hague (1720), the island of Sardinia and its title of kingdom were ceded by the Habsburg and Bourbon claimants to the Spanish throne to the Duke of Savoy, Victor Amadeus II. The Savoyards united it with their historical possessions on the Italian peninsula, and the kingdom came to be progressively identified with the peninsular states, which included, besides Savoy and Aosta, dynastic possessions like the Principality of Piedmont and the County of Nice, over both of which the Savoyards had been exercising their control since the 13th century and 1388, respectively.

Liguria (/lɪˈɡjʊəriə/ lig-YOOR-ee-ə, Italian: [liˈɡuːrja]; Ligurian: Ligûria [liˈɡyːɾja]) is a region of north-western Italy; its capital is Genoa. Its territory is crossed by the Alps and the Apennines mountain range and is roughly coextensive with the former territory of the Republic of Genoa. Liguria is bordered by France (Provence-Alpes-Côte d'Azur) to the west, Piedmont to the north, and Emilia-Romagna and Tuscany to the east. It rests on the Ligurian Sea, and has a population of 1,509,908 as of 2025. The region is part of the Alps–Mediterranean Euroregion.

The Lombard language (Lombard: lombard, lumbard, lumbart or lombart, depending on the orthography; pronunciation: [lũˈbaːrt, lomˈbart]) belongs to the Gallo-Italic group within the Romance languages. It is characterized by a Celtic linguistic substratum and a Lombardic linguistic superstratum and is a cluster of homogeneous dialects that are spoken by millions of speakers in Northern Italy and southern Switzerland. These include most of Lombardy and some areas of the neighbouring regions, notably the far eastern side of Piedmont and the extreme western side of Trentino, and in Switzerland in the cantons of Ticino and Graubünden. The language is also spoken in Santa Catarina in Brazil by Lombard immigrants from the Province of Bergamo, in Italy.

Montferrat (UK: /ˌmɒntfəˈræt/ MONT-fə-RAT, US: /-ˈrɑːt/ -⁠RAHT; Italian: Monferrato [moɱferˈraːto]; Piedmontese: Monfrà, locally [mʊŋˈfrɒ]; Latin: Mons Ferratus) is a historical region of Piedmont, in northern Italy. It comprises roughly (and its extent has varied over time) the modern provinces of Alessandria and Asti. Montferrat is one of the most important wine districts of Italy. It also has a strong literary tradition, including the 18th-century Asti-born poet and dramatist Vittorio Alfieri and the Alessandrian Umberto Eco.

The territory is cut in two by the river Tanaro. The northern part (the Basso Monferrato, "Low Montferrat"), which lies between that river and the Po, is an area of rolling hills and plains. The southern part (the Alto Monferrato, "High Montferrat") rises from the banks of the Tanaro into the mountains of the Apennines and the water divide between Piedmont and Liguria.
