THE RISE OF THE ASHIKAGA HOUSE I79
branch of the imperial house. As a consequence, the Ashikaga family
observed two loyalties: one to the shogun and the Hojo regency and
the other to the imperial house. Ashikaga Takauji, whose defection led
to the demise of the Kamakura shogunate, made his move in part in
the name of Godaigo (1288-1339), head of the Daikakuji line.
It was Yoshiyasu's son, Yoshikane (?-H99), who joined Minamoto
Yoritomo's cause in 1180 and thereby brought the Ashikaga family
into the service of the Kamakura military government. Before 1180,
Yoshikane had married one of Hojo Tokimasa's daughters. Another
daughter, Masako (1157-1225), had married Minamoto Yoritomo.
Thus Yoshikane found himself married to the sister of the wife of
Yoritomo, the first shogun. The Hojo connection was actively main-
tained thereafter, so that during the Kamakura period, of seven genera-
tions of Ashikaga chiefs, five took Hojo wives. Takauji, at the time of
his defection, was married to the sister of the last regent. It is signifi-
cant, however, that Takauji did not have a Hojo mother; his father had
married into the Uesugi, an important military house based in Tamba
Province, west of the capital.
In the third generation after Yoshiyasu, the Ashikaga lineage began
to segment and spread out beyond the home province. Two of
Yoshikane's sons were the first to move out of Shimotsuke. One went
to Kozuke and took the name Momonoi and the other went to
Musashi and took the name Hatakeyama. Three members of the next
generation moved into Mikawa Province, where they took the place
names Niki, Hosokawa, and Togasaki as their own. Then, other
members of the lineage established three more branch families, the
Kira, Imagawa, and Isshiki in Mikawa. This concentration of hold-
ings in Mikawa probably explains why the head of the house was ap-
pointed
shugo
of Mikawa in 1238. The Ashikaga were awarded Kazusa
as well, in 1259, but Shimotsuke, the locus of their ancestral holding,
remained in the hands of the long-entrenched Koyama family.
Although there is some information about the number of branch
families and the location of their holdings, there
are.
almost no data on
the size and value of these possessions. Collateral families constituted a
first line of support for the chief of the Ashikaga line. By Takauji's
generation, these included the Momonoi, Hatakeyama, Niki,
Hosokawa, Kira, Imagawa, Isshiki, Ishido, Shibukawa, and Shiba
