The Aksumite Empire developed Ge'ez, one of the world's oldest continuously used writing systems and the only indigenous African alphabet still in widespread use today (as the basis for Amharic and Tigrinya). Originally a 'pure' alphabet like Phoenician (writing only consonants), it evolved during the 4th century into an 'abugida'—a system where each character represents a consonant-vowel syllable. This change is often attributed to the need for precise translation of Christian scriptures. The script's unique geometric aesthetics and its preservation of ancient Semitic linguistic features make it a vital part of African and global heritage, used for both sacred religious texts and the administration of one of antiquity's most sophisticated states.
