the turkic tribes 431rude to T’u-tung, who had him whipped. This gave Kuang-sheng a
pretext to massacre the Uighurs. He confiscated several 1000 of their
camels and horses and 100,000 bolts of silk and sent the women back
to Ch’ang-an.
Te-tsung summoned Chang Kuang-sheng to the capital and pro-
moted him to General of the Gilded Mace of the Right. He also sent
a eunuch to accompany a returning Uighur envoy and inform the
qaghan that in view of the circumstances he was braking off relations
with the [Uighur] barbarians (Hsin T’ang shu 217A:7b; Tzu-chih t’ung-
chien pp.7287-7288).
In 781, Te-tsung sent the envoy Yüan Hsiu to return the corpses
of T’u-tung, Yi-mi-shih, and two others to their country. A messenger
of the qaghan told Hsiu that he should be killed in retaliation for the
murder of T’u-tung. Hsiu blamed the death on Chang Kuang-sheng,
absolving Emperor Te-tsung. He was not allowed to see the qaghan
and was detained for 50 days. When he was permitted to return, the
qaghan attached a Uighur envoy to him with the message that the
T’ang had welshed on 1,800,000 strings of cash owed for Uighur
horses. They reached Ch’ang-an on Aug.11, 782 The emperor
“restrained his feelings” and paid 100,000 bolts of silk and 100,000
ounces of gold and silver (Hsin T’ang shu 217A:7b-8a; Tzu-chih t’ung-
chien pp.7330-7331).^69
On Oct.2, 787,^70 a chief sent by the qaghan offered regional objects^71
and requested a marriage alliance. Te-tsung was at first adamantly
opposed but finally gave in to the insistant entreaties of the Grand
Councilor Li Pi (722-789). He selected his eighth daughter, the Prin-
cess of Hsien-an, and ordered her to give an audience to the Uighur
envoy. When the latter returned to his country on Oct.28, he brought
with him a promise of the marriage as well as a portrait of the future
bride (Chiu T’ang shu 12:25a-25b; 196:9b; Hsin T’ang shu 217A:8a-9a,
10a;T’ang hui-yao 98:5a; Tzu-chih t’ung-chien pp.7505-7506; Wen-hsien
t’ung-k’ao 347:29a).
In the 5th month (June/July) of 788, Uighur envoys were received
at the T’ang court (Ts’e-fu yüan-kuei p.5032).
(^69) On the dates, see Mackerras, Uighur Empire, p.154 note 155.
(^70) Tzu-chih t’ung-chien p.7501 dates the arrival of this mission 9th month (Oct./
Nov.).Chiu T’ang shu 12:15a-25b has Oct.28, but that, according to Tzu-chih t’ung-chien
p.7505, was the date of its return.
(^71) These must have included horses, since the emperor paid 50,000 bolts of
pongee specifically for horses (Tzu-chih t’ung-chien p.7506).
