Ameshab Ngakwang Kunga Sonam (A myes zhabs ngag dbang kun dga' bsod nams, 1597-1659) was the long-serving twenty-seventh throne holder of the Sakya lineage of Tibetan Buddhism. Deeply trained in his tradition, Ameshab was ordained as a monk around 1618 and undertook extensive scholastic study. After the death of his father and brother, however, in 1620 Ameshab returned his vows and was enthroned as Sakya Trizin. In the decades that followed, Ameshab widely promoted the transmission of the Sakya tradition and mediated peace amid rising military conflict in Central Tibet. A prodigious historian, Ameshab wrote impactful histories of the Sakya school; the Lamdré, or "Path and Result," tradition; and the Hevajra Tantra, which were read for centuries in Tibet and across the Inner Asian Buddhist world.
