the southwest 229Cavalry, entitled him king of Hsi-hai commandery, and presented him
with 2000 items of objects. Srong-btsan-sgam-po responded with 3000
items of gold (Chiu T’ang shu 196A:3a; Tzu-chih t’ung-chien p.6268).
In the 1st month (Feb./Mar.) of 650, Tibetan envoys offered gifts
(Ts’e-fu yüan-kuei p.5025).
At some time in early 650, Kao-tsung entitled Srong-btsan-sgam-po
“Guest King” (Wen-hsien t’ung-k’ao 334:28b).
On June 28, 650, it became known at the T’ang court that Srong-
btsan-sgam-po had died. Kao-tsung commenced mourning for him.
He sent the General of the Martial Guards of the Right with a let-
ter stamped with the imperial seal to condole and sacrifice. Since
Srong-btsan-sgam-po’s sons had died before him, he was succeeded
by a grandson. The latter was not yet of age, and the affairs of state
were managed by the above-mentioned Chancellor, Lu Tung-tsan
(Chiu T’ang shu 4:2b; 196A:3a; Tzu-chih t’ung-chien p.6271; Wen-hsien
t’ung-k’ao 334:28b).

p.5025).
In the 12th month (Jan./Feb., 658) of the Chinese year 657, envoys
from the king of Tibet presented a town made of gold. On it were
images of a lion, a camel, a horse, a ram etc. each with a rider (Ts’e-
fu yüan-kuei p.5025).
In the 10th month (November) of 659, the new Tibetan king unsuc-

In the 6th month (July/Aug.) of 660, the Tibetans attacked the
T’u-yü-hun at Ch’ing-hai (Kokonor). In the 6th month (July/Aug.) of
663, Tibetan envoys to the T’ang court complained about the T’u-yü-
hun and again asked for a marriage. Kao-tsung rejected this. He sent a
General of the Gentlemen of the Guards of the Left to take a critical
letter stamped with the imperial seal to the Tibetans. On Feb.14, 665,
he received Tibetan envoys in audience. They again requested a mar-
riage and a border adjustment in their favour. The emperor refused.
In the 7th month (July/Aug.) of 670, the Tibetans renewed their attack
on the T’u-yü-hun and defeated a Chinese army sent to their rescue.
The king of the T’u-yü-hun fled and sought Chinese protection in the
eastern Kan-su Corridor, while his old territory was annexed by by the
Tibetans. Henceforth, the relations between the Tibetans and T’ang
were tense, and the Tibetans looted Chinese border lands (Chiu T’ang
