The shrine was first built in 947 to appease the angry spirit of bureaucrat, scholar and poet Sugawara no Michizane, who had been exiled as a result of political maneuvers of his enemies in the Fujiwara clan. The shrine became the object of Imperial patronage during the early Heian period. In 965, Emperor Murakamiordered that Imperial messengers be sent to report important events to the guardiankami of Japan. These messenger, called heihaku, were initially presented to 16 shrines; and in 991, Emperor Ichijō added three more shrines to Murakami's list — including Kitano. From 1871 through 1946, the Kitano Tenman-gū was officially designated one of the Modern system of ranked Shinto Shrines, meaning that it stood in the second rank of government supported shrines.
The shrine was dedicated to Michizane; and in 986, the scholar-bureaucrat was deified and the title of "Tenjin" was conferred. serving tea at the plum blossom festival. The grounds are filled with Michizane's favorite tree, the red and white ume'' or plum blossom, and when they blossom the shrine is often very crowded. The Plum Blossom Festival is held on February 25, coinciding with the monthly market. An open-air tea ceremony is hosted by geiko and apprentice maiko from the nearby Kamishichikendistrict, where tea and wagashi are served to 3,000 guests by geisha and maiko. The plum festival has been held on the same day every year for about 900 years to mark the death of Michizane. The outdoor tea ceremony dates back to 1952. In that year, a big festival was held to mark the 1,050th anniversary of Michizane's death, based on the historic Kitano Ochakai tea ceremony hosted at the shrine by Toyotomi Hideyoshi. Kitano Tenmangū is popular with students praying for success in exams because the deity was in his life a man of literature and knowledge. On the 25th of every month, the shrine hosts a flea market. Together with the similar festival at Tō-ji, a temple in the same city, they inspired the Kyoto proverb, "Fair weather at the Tōji market means rainy weather at the Tenjin market," calling to mind Kyoto's fickle weather.
