Gar Trinring Tsendro

After his elder brother Tsenye Dompu succeeded the Lönchen, he was sent to 'A-zha to defend against Tang dynasty. In the spring of 670, Tibet attacked the remaining Chinese territories in the western Tarim Basin. The Chinese general Xue Rengui led over 100 thousand soldiers invaded 'A-zha, tried to conquer Tibet, but was defeated by Trinring by the Dafei River and near annihilation.

Gar Tsenye Dompu came into conflict with another minister Gar Mangnyen Taktsab (མགར་མང་ཉེན་སྟག་ཙབ), then, met on the battleground in 685. Tsenye died by a river in Sumpa. Obtaining this information, Trinring quickly put down the rebellion. Mangnyen Taktsab disappeared after this event, maybe was purged. Thrimalö, who was the de facto ruler at that time, appointed him as the new Lönchen.

Trinring showed his extraordinary military talent in hundreds of battles against the Chinese. China had to negotiate with Tibet, but could not reach a consensus because China wanted Tibet leave 'A-zha while Tibet wanted China leave the Tarim Basin.

Trinring owned very high reputation in Tibet, which led ultimately to his ruin. The young king, Tridu Songtsen, realised that members of the Gar family had become independent warlords and posed a threat to the central authority of the king. In 699, the king pretended to organise a great hunt and then had his men turn on members of the Gar and their supporters, Then personally marched north and confronted Trinring. Trinring tried to resist, but his armies betrayed him, he had to commit suicide.

Gar family were purged in this coup d'état. His son Mangpoje (known as Lun Gongren (論弓仁) by Chinese) fled to China together with one of his brothers, Gar Tsenba (མགར་བཙན་པ).
