The Indo-European languages are a family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by Ethnologue, with over two-thirds (313) of them belonging to the Indo-Iranian branch. The Indo-European family includes most major current languages of Europe, and parts of Western, Central and South Asia. It was also predominant in ancient Anatolia (present-day Turkey), and the ancient Tarim Basin (present-day Northwest China) and most of Central Asia until the invasion and migrations of Turkic speakers especially during the Mongol–Turkic conquest in the 13th century. With written attestations appearing since the Bronze Age in the form of the Anatolian languages and Mycenaean Greek, the Indo-European family is significant to the field of historical linguistics as possessing the second-longest recorded history, after the Afroasiatic family.
