The Emperor of era of daibutu was "Shomu".
His lineage was the emerging powerful family named "Fujiwara".
Fujiwara clan led the coup of 100 years ago.
Since its success，they were deeply connected to the Imperial Family.

One issue had been going on here.
Shomu wanted to give Emperor place to the son of Fujiwara lineage.　
（Mother born in Fujiwara clan）
But his son did not exist at this time because died young.

Son of different clan lineage become emperor.
It means that the power was transferred to there.

”This is temporary measures until the Fujiwara lineage son born.”
　
He had appointed to the throne heir to daughter of Fujiwara lineage.
（As at that time was unusual measures.）

・・・・・・・・・
　
Smallpox occurred in 737 AD.

The man who was at the helm of the court named "Fujiwara-no-fuhito".
His four sons died one after another in the smallpox.
　
As a result,  the man named "Tachibana-no-moroe" became "Dainagon".
（Dainagon the position of number four of the court.）　
Fujiwara clan  forces of emerging yet had been forced to retreat.

At that time，the only son of Shomu died suddenly.
He had the expectations of anti-Fujiwara forces.　
There was also the possibility of assassination.

In 748 AD，"Gansho Dajoten-no" died.
Dajoten-no is the name of the emperor abdicated.
And Gansho Dajoten-no was the maximum force of the anti-Fujiwara. 　
　
Shomu was abdication in the form of an eye for an eye *.
And his daughter was crowned as ”Emperor Koken”in 749 AD.

When she ascended，Fuziwara-no-nakamaro became Dainagon in an unusual career.
He was not a mainstream.
（Subsequent notation, Nakamaro）
Because four sons of Fuziwara-no-fufito were all dead.

At the same time，son of Tachibana-no-moroe became Sangi(the sixth position).

Conflict between the two had became increasingly fierce.
