The Sequani were a Celtic tribe that inhabited the region of modern-day eastern France, particularly around the area of the Doubs River. They were known for their agricultural practices and their interactions with neighboring tribes, including the Aedui and the Burgundians. The Sequani played a significant role in the political dynamics of Gaul during the late Iron Age and early Roman period. During the Roman conquest of Gaul, the Sequani allied with the Romans against other tribes, such as the Helvetii. Their territory was eventually incorporated into the Roman Empire, leading to significant cultural and economic changes in the region. The Sequani's legacy is reflected in the archaeological sites and historical accounts from that era.
