The rise of the Fujiwara is closely linked to the rise of the Imperial family. The Fujiwara family was previously called Nakatomi, but after Prince Naka no Oe took the coup, helped by the Nakatomi family, it changed its name to Fujiwara (wisteria field), in honor of the place where it was the coup was idealized. The Fujiwara quickly became Japan's main family, even surpassing the Imperial family. This is because, thanks to the fact that Japan did not adopt the Chinese custom of appointing important people to those who stood out for their qualities, the Fujiwara always occupied such positions. But, in addition to the fact that the Fujiwara clan occupied the main administrative positions of the Empire, the biggest reason why he acquired preponderance was to be able to always connect with the Imperial family, since the majority of the emperors' wives, and consequently the mothers of the future Emperors, belonged to the clan.
From an early age, the Fujiwara managed to acquire many lands, becoming one of the main landowners in Japan. As a result, they formed an extensive base of warriors and political support to, starting in 858, start their rule in the country. The control that the Fujiwara exercised over the Emperor intensified from that date, as they put into practice even more the policy that they had been developing since his accession.
