Piedmont is surrounded on three sides by the Alps, including Monviso (Mont Vis), where the Po rises, and Monte Rosa. It borders France, Switzerland and the Italian regions of Lombardy, Liguria, Aosta Valley and for a very small fragment with Emilia Romagna. The geography of Piedmont is 43.3% mountainous, along with extensive areas of hills (30.3%) and plains (26.4%).
Piedmont is the second largest of Italy's 20 regions, after Sicily. It is broadly contiguous with the upper part of the drainage basin of the river Po, which rises from the slopes of Monviso in the west of the region and is Italy’s largest river. The Po collects all the waters provided within the semicircle of mountains (Alps and Apennines) which surround the region on three sides.
From the highest peaks the land slopes down to hilly areas, (not always, though; sometimes there is a brusque transition from the mountains to the plains) and then to the upper, and then the lower the great Padan Plain. The boundary between the first and the second is characterised by risorgive, springs typical of the pianura padana which supply fresh water both to the rivers and to a dense network of irrigation canals. The countryside, then, is very varied: one passes from the rugged peaks of the massifs of Monte Rosa and of Gran Paradiso (national park), to the damp rice paddies of the Vercellese and Novarese; from the gentle hillsides of the Langhe and of Montferrat to the plains.
The percentage of the territory which is a protected area is 7.6%. There are 56 different national or regional parks. One such park is the Gran Paradiso National Park (Grand Paradis).

Piedmont was inhabited in early historic times by Celtic-Ligurian tribes such as the Taurini and the Salassi. They were later submitted by the Romans (c. 220 BC), who founded several colonies there including Augusta Taurinorum (Turin) and Eporedia (Ivrea). After the fall of the Western Roman Empire, the region was repeatedly invaded by the Burgundians, the Goths (5th century), Byzantines, Lombards (6th century), Franks (773).
In the 9th-10th centuries there were further incursions by the Magyars and Saracens. At the time Piedmont, as part of the Kingdom of Italy within the Holy Roman Empire, was subdivided into several marks and counties.
Kingdom of Sardinia-Piedmont in 1856.
In 1046, Oddo of Savoy added Piedmont to their main territory of Savoy, with a capital at Chambéry (now in France). Other areas remained independent, such as the powerful comuni (municipalities) of Asti and Alessandria and the marquisates of Saluzzo and Montferrat. The County of Savoy was elevated to a duchy in 1416, and Duke Emanuele Filiberto moved the seat to Turin in 1563. In 1720, the Duke of Savoy became King of Sardinia, founding what evolved into the Kingdom of Sardinia-Piedmont and increasing Turin's importance as a European capital.
The Republic of Alba was created in 1796 as a French client republic in Piedmont before the area was annexed by France in 1801. In June 1802 a new client republic, the Subalpine Republic, was established in Piedmont and in September it was also annexed. In the congress of Vienna, the Kingdom of Sardinia-Piedmont was restored, and furthermore received the Republic of Genoa to strengthen it as a barrier against France.
Piedmont was an initial springboard for Italy's unification in 1859-1861, following earlier unsuccessful wars against the Austrian Empire in 1820-1821 and 1848-1849. This process is sometimes referred to as Piedmontisation. However, the efforts were later contradicted by efforts of rural farmers.[3][4] The House of Savoy became Kings of Italy, and Turin briefly became the capital of Italy. However, the addition of territory paradoxically reduced Piedmont's importance to the kingdom, and the capital was moved to Florence, and then to Rome. One remaining recognition of Piedmont's historical role was that the crown prince of Italy was known as the Prince of Piedmont.
