Mazu or Matsu is a Chinese sea goddess also known by several other names and titles. She is the deified form of the legendary figure Lin Mo or Lin Moniang, a Fujianese shamaness whose life span is traditionally dated from 960 to 987. Revered after her death as a tutelary deity of seafarers, including fishermen and sailors, her worship spread throughout China's coastal regions and overseas Chinese communities throughout Southeast Asia and overseas, where some Mazuist temples are affiliated with famous Taiwanese temples. She was thought to roam the seas, protecting her believers through miraculous interventions. She is now generally regarded by her believers as a powerful and benevolent Queen of Heaven. Mazu worship is popular in Taiwan as large numbers of early immigrants to Taiwan were Hoklo people; her temple festival is a major event in the country, with the largest celebrations around her temples at Dajia and Beigang. Under Xi Jinping, Mazu-related pilgrimages have become an avenue for Chinese Communist Party influence operations to promote Chinese unification.
