Explanation:

The Chola dynasty, particularly the later Cholas, were ardent patrons of Shaivism, a major tradition within Hinduism centered on the worship of Lord Shiva. They commissioned and built numerous magnificent Shiva temples, such as the Brihadeeswarar Temple at Thanjavur, which stand as enduring testaments to their devotion and architectural prowess. While other religions existed, Shaivism received the most significant royal patronage.
