Strolling About in Spring, by Zhan Ziqian, Sui era artist.

Buddhism was popular during the Six Dynasties period that preceded the Sui dynasty, spreading from India through Kushan Afghanistan into China during the Late Han period. Buddhism gained prominence during the period, when central political control was limited. Buddhism created a unifying cultural force that uplifted the people out of war and into the Sui Dynasty. In many ways, Buddhism was responsible for the rebirth of culture in China under the Sui Dynasty.

The Emperor Wen and his empress had converted to Buddhism to legitimate imperial authority over China and the conquest of Chen. Wendi presented himself as a Cakravartin king, a Buddhist monarch that would use military force to defend the Buddhist faith, much like the notion of Jihad in Islam.In the year 601 AD, Emperor Wen had relics of the Buddha distributed to temples throughout China, with edicts that expressed his goals, "all the people within the four seas may, without exception, develop enlightenment and together cultivate fortunate karma, bringing it to pass that present existences will lead to happy future lives, that the sustained creation of good causation will carry us one and all up to wondrous enlightenment".^[8] Ultimately, this act was an imitation of the ancient Mauryan Emperor Ashoka of India.
