Traditional Mongolian Script

Following the lineage Sogdian→Uyghur→Mongolian, this script adopted in the 13th-century Mongol Empire is the world's only living vertical script written top-to-bottom, left-to-right. Mongolia's national anthem and constitution are recorded in it. Replaced by Cyrillic during Soviet rule (1924–1990), it remains an official script in Inner Mongolia (China) and is experiencing active revival.
