The village of San Biagio Sarasinisco in the south of the Lazio is situated halfway between Rome and Naples, 36 kilometres (22 mi) from Monte Cassino.

Two main flows of emigration marked the evolution of the population: in 1915 a first wave (approximately one quarter) moved to Rome, Milan, Paris, Berlin etc.

; after 1960 a second wave (half of the population) left the village to go to foreign countries in Northern Europe, but also to the United States and Brazil.

San Biagio (Saint Blaise), whose relics are in many local churches, is revered by the Benedictine Monks of the Monte Cassino Abbey, set up in 529 on land above the Valley of Comino.

Little by little they abandoned this natural housing environment in favor of small strengthened installations made of polygonal walls on the plateau of Mount Santa Croce.

Excavations made in the place known as Omini Morti brought to light a necropolis of Etruscan type with skeletons adorned with bronze belts, iron lances, jewels as well as vases enameled in terracotta and painted.

Because of its closeness with the way Sora-Venafro-Capua, which winds between the mountains, this village and many around were less controlled than the ones on the way between Rome and Naples situated in the plain, so they were the theater of numerous revolts and wars against the Roman power, particularly against the slavery in the 4th and 3rd centuries BC.

After the fall of the Roman Empire, the territory was successively occupied by the Ostrogoths of Alaric I (410), the Vandals (476), the Herules, then the Lombards and the Saracens.

In 1055 Pandolfo and Landolfo, Lords of Capua, gave this land to the monks of Monte Cassino who lent the ground to shepherds living in Picinisco, Agnone and Atina, Lazio.

In 1678 the monks decided to set up a chapel to Saint Blaise; some families coming from Cervaro, San Vittore del Lazio, Rocca d'Evandro and Cassino settled there.

In the 16th century, Swadan[dubious – discuss] (leader of a gang) with his men used to attack villages and rob travelers.

[citation needed] By decree of Ferdinand II, King of Naples, in 1858, the village obtained its autonomy with more than 1000 inhabitants, and became the town of San Biagio Sarasinisco, in the province of Terra Laboris.

The poverty forced a quarter of them to move to the big northern Italian cities, to Germany, to France, Switzerland, Scotland, England, Sweden and even the United States.

With the shade of the war and the closeness of Cassino, General Kesselring decided to create the Gustav Line, which divided the country into parts.

There were many fights in this territory, thousands of soldiers from all over the world (Africa, Australia, America, Europe) fought on these hills and the surrounding mountains.

The building of a leisure center on the beach of the lake, of a youth hostel and a restaurant attracts walkers and cyclists.

On 8 August, in the historic center, is the la Sagra del Frattaccio with dancers and folk music, and ended by fireworks.
