The Chola Navy was a powerful maritime force established by the Chola dynasty, which ruled parts of southern India from the 9th to the 13th centuries. This navy played a crucial role in expanding the dynasty's influence across the Indian Ocean, enabling trade and military expeditions to regions like Southeast Asia. The Chola rulers built advanced ships and trained skilled sailors, making their navy one of the most formidable of its time. Under the leadership of notable kings like Rajaraja Chola I and his son Rajendra Chola I, the Chola Navy conducted successful campaigns against rival kingdoms and established trade routes. Their naval prowess contributed to the spread of culture, religion, and commerce, significantly impacting the history of maritime activities in the region.
