Each lineage of descendants of four Fujiwara brothers was called 'Fujiwara Nanke' (the Southern House of the Fujiwara clan), 'FUJIWARA Hokke' (the Northern House of the Fujiwara clan), 'Fujiwara Shikike' (the Ceremonial House of the Fujiwara clan), and 'Fujiwara Kyoke' (the Western House of the Fujiwara clan); although they went through the rise and fall, they left a major mark on later politics, learning, and culture.
藤原四兄弟の子の系統はそれぞれ藤原南家、藤原北家、藤原式家、藤原京家と呼ばれ、それぞれの家に栄枯盛衰はあったものの、その後の政治や学問、文化に大きな足跡を残している。
