Principally the main passageway between the peninsula and the rest of the country, the region of Thies has received a communication route connected to the first rail line and new road infrastructure.
The Thiès Region has always been occupied by the Serer people since the ancient Serers and their ancestors. However in the pre-colonial period, more so around the 16th century, the Wolof immigrants among others have settled in. Like the Fatick Region, the entire Thiès Region is strongly Serer and one of the most important of Serer country. It is also where many of the Serer sacred and historical sites are found. The area is well represented by the Cangin, a sub-group of the Serers, who had a fierce reputation for protecting their country from outsiders in precolonial times as well as during the colonial-era (see Timeline of Serer history and Serer medieval history).
Geographically, the region partially overlaps with the precolonial Kingdoms of Cayor and Baol. The Kingdom of Baol was ruled by the Joof family for several centuries until c 1549. During the colonial-era, its development was supported by the railway line - the Dakar-Saint-Louis railway in the late nineteenth century, and then with the Dakar-Niger railway. Thus Administratively, it is one of the oldest in the country.
The region is divided into 3 departments (départements) as follows':
- Médina Dakhar
- Taïba Ndiaye
- Mont Rolland
- Notto Gouye
- Chérif Lo
- Pire Gourèye
