of Middle East and South and Central Asia, the common root is "yun" or "ywn". It is borrowed from the Greek name Ionia, a once Greek region of Asia Minor, and the Ionians: (Yūnān) or (Yawān, Yawon) (Hunastan) (Yunastan) (Yūnān) (Yāwān) (Yavan) (Yūnān) (Yūnān) (Yūnān) (Yauna) (Yavana) (Yunon) The third form is "Hellas", used by a few languages around the world, including Greek: Greek: or Polytonic: or Monotonic: or (rare usage) (used for Ancient Greece) (Hanyu Pinyin: Xīlà; Jyutping: hei1 laap6) (rare usage) Other forms: (Hrōmāyīg) Laz: Xorumona (ხორუმონა) (Saberdzneti) Brief history The first people speaking an ancient Proto-Greek language entered mainland Greece during the Neolithic period or the Bronze Age. From the Ancient Greek dialects as they presented themselves centuries later, it seems that at least two migrations of Greeks occurred overall, the first of the Ionians and the Aeolians probably in the 19th century BC and the second of the Dorians probably in the 13th century BC. The first migration resulted in Mycenean Greek, an archaic Greek language which appears in Linear B syllabic inscriptions and the second resulted in the Dorian dialect which displaced the Arcadocypriot dialect that seems to be closest to the Mycenean Greek. The tribes later called Aeolians and Ionians established several feudal kingdoms around Greece, and the historians called them Myceneans after their most powerful kingdom Mycenea in Peloponnese, or Myceneans-Achaeans because in Homer the Achaeans were the dominating tribe in Greece and the name Achiyawa that appears in Hittite texts seems to correspond to a thalassocratic country which might be Mycenea. Although Homer referred to a union of the Greek kingdoms under the leadership of the king of Mycenae during the Trojan War, there is no evidence that these kingdoms were dominated by a central power. Most of the Mycenaean palaces were destroyed at the end of the 13th century BC. The Greek tradition relates this destruction to the Dorians, but it is suggested that the Dorian invasion was only one of the causes of the Bronze Age collapse in the Eastern Mediterranean, as there is no evidence that the newcomers established a different civilization. The destruction was followed by the Greek Dark Ages with very poor archaeological findings, when most occupied areas were deserted, but some areas like Attica occupied by the Ionians remained untouched by the invaders. Several Greek tribes moved to regions of Greece where they acquired different names,
