Ulos: The Woven Cloth of North Sumatra That Conquered the World Attire: A Comprehensive Study of Heritage, Philosophy, and Global Cultural Diplomacy What does it mean for a piece of cloth to carry an entire civilization on its threads? In the highlands around Lake Toba, the answer is woven into every ulos—the sacred textile of the Batak peoples, a cloth that is at once memory, cosmology, kinship, prayer, and diplomacy. This book is the first comprehensive study of Ulos in English, tracing the cloth from its mythological origins in the hands of the goddess Si Boru Deak Parujar to its contemporary emergence as an instrument of Indonesian cultural diplomacy. Drawing on oral traditions, Pustaha manuscripts, colonial records, and extensive fieldwork, it explores the philosophical foundations of the Batak worldview—the tondi or life force, the Dalihan Na Tolu kinship system, the sahala or spiritual power of the wife-givers—and shows how these principles are encoded in the motifs, colors, and rituals of the cloth. The book examines the craft itself: the backstrap loom (ludang), the supplementary weft and ikat techniques, the natural dyes of indigo and morinda, and the sacred taboos that govern the weaving process. It analyzes the role of Ulos in the great rites of passage—birth, marriage, and death—and in the ceremonies of Mangulosi, Mangirdak, and Martutu, where the cloth serves as the medium through which blessings, obligations, and ancestral presence are transmitted. Beyond the highlands, the study follows Ulos into the modern world: its commodification and the threat of machine-made imitations, its revival through cooperatives and social media, its adoption by contemporary fashion designers, and its growing role in cultural diplomacy, from Indonesian embassies to international expos. It also confronts the challenges of intellectual property, ethical sourcing, and the urgent question of whether the tradition can survive the pressures of globalization. Written with scholarly rigor and deep respect for the Batak people, this book is both a definitive reference and an invitation—to scholars, students, weavers.
