Lydia in the context of "Siglos"

The Achaemenid Empire (/əˈkiːmənɪd/ ə-KEE-mə-nid; Old Persian: 𐎧𐏁𐏂, Xšāça, lit. 'The Empire' or 'The Kingdom') was an ancient Iranian empire founded by Cyrus the Great of the Achaemenid dynasty in 550 BC. At peak, its territorial extent was roughly 5.5 million square kilometres (2.1 million square miles), making it the largest empire of its time. Based in the Iranian plateau, it stretched from the Balkans and Egypt in the west to the Indus Valley in the east, including Anatolia, Cyprus, Mesopotamia, the Levant, parts of Eastern Arabia, and large parts of Central Asia.

By the 7th century BC, the region of Persis, located in the southwestern part of the Iranian plateau, had been settled by Persians. From Persis, Cyrus rose and defeated Media, Lydia, and the Neo-Babylonian Empire, thus marking the establishment of a new imperial polity in the ancient Near East. While its conquests were largely successful in most regions, the Achaemenid Empire's attempts to expand into Greece proved extremely difficult over the course of decades of wars and multiple kings, ultimately resulting in its defeat in the Greek mainland.

Ankara is the capital city of Turkey. Located in the central part of Anatolia, the city has a population of over 5,200,000 in its urban center and 5,864,049 in Ankara Province (total of 25 districts). Ankara is Turkey's second-largest city by population after Istanbul.

Ankara was historically known as Ancyra and Angora. Serving as the capital of the ancient Celtic state of Galatia (280–64 BC), and later of the Roman province with the same name (25 BC–7th century), Ankara has various Hattian, Hittite, Lydian, Phrygian, Galatian, Greek, Persian, Roman, Byzantine, and Ottoman archeological sites. The Ottomans made the city the capital first of the Anatolia Eyalet (1393 – late 15th century) and then the Angora Eyalet (1827–1864) and the Angora Vilayet (1867–1922). On 23 April 1920, the Grand National Assembly of Turkey was established in Ankara, which became the headquarters of the Turkish National Movement during the Turkish War of Independence. Ankara became the new Turkish capital upon the establishment of the Republic on 29 October 1923, succeeding in this role as the former Ottoman capital Istanbul following the fall of the Ottoman Empire.

Classical Anatolia is Anatolia during classical antiquity. Early in that period, Anatolia was divided into several Iron Age kingdoms, most notably Lydia in the west, Phrygia in the center and Urartu in the east. Anatolia fell under Achaemenid Persian rule c. 550 BC. In the aftermath of the Greco-Persian Wars, all of Anatolia remained under Persian control except for the Aegean coast, which was incorporated in the Delian League in the 470s BC. Alexander the Great finally wrested control of the whole region from Persia in the 330s BC. After Alexander's death, his conquests were split amongst several of his trusted generals, but were under constant threat of invasion from both the Gauls and other powerful rulers in Pergamon, Pontus, and Egypt.

The Seleucid Empire, the largest of Alexander's territories, and which included Anatolia, became involved in a disastrous war with Rome culminating in the battles of Thermopylae and Magnesia. The resulting Treaty of Apamea in (188 BC) saw the Seleucids retreat from Anatolia. The Kingdom of Pergamum and the Republic of Rhodes, Rome's allies in the war, were granted the former Seleucid lands in Anatolia. Anatolia subsequently became contested between the neighboring rivalling Romans and the Parthian Empire, which frequently culminated in the Roman–Parthian Wars.

A tumulus (pl.: tumuli) is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds, mounds, howes, or in Siberia and Central Asia as kurgans, and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus.

Tumuli are often categorised according to their external apparent shape. In this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves. A round barrow is a round tumulus, also commonly constructed on top of burials. The internal structure and architecture of both long and round barrows have a broad range; the categorization only refers to the external apparent shape.

Ionia (/aɪˈoʊniə/ eye-OH-nee-ə) was an ancient region encompassing the central part of the western coast of Anatolia. It consisted of the northernmost territories of the Ionian League of Greek settlements. Never a unified state, it was named after the Ionians who had settled in the region before the archaic period.

Ionia proper comprised a narrow coastal strip from Phocaea in the north near the mouth of the river Hermus (now the Gediz), to Miletus in the south near the mouth of the river Maeander, and included the islands of Chios and Samos. It was bounded by Aeolia to the north, Lydia to the east and Caria to the south. The cities within the region figured significantly in the strife between the Persian Empire and the Greeks.

Cyrus II of Persia (c. 600 – 530 BC), commonly known as Cyrus the Great, was the founder of the Achaemenid Empire. Hailing from Persis, he brought the Achaemenid dynasty to power by defeating the Median Empire and embracing all of the previous civilized states of the ancient Near East, expanding vastly across most of West Asia and much of Central Asia to create what would soon become the largest empire in history at the time. The Achaemenid Empire's greatest territorial extent was achieved under Darius the Great, whose rule stretched from Southeast Europe in the west to the Indus Valley in the east.

After absorbing the Median Empire, Cyrus conquered Lydia and eventually the Neo-Babylonian Empire, granting him control of Anatolia and the Fertile Crescent, respectively. He also led a major expedition into Central Asia, where his army brought "into subjection every nation without exception" before he allegedly died in battle with the Massagetae, a nomadic Eastern Iranian people, along the Syr Darya in December 530 BC. However, according to Xenophon of Athens, Cyrus did not die fighting and had instead returned to the capital city of Pasargadae. Regardless of the date of his death, he was succeeded by his son Cambyses II, whose campaigns into North Africa led to the conquests of Egypt, Nubia, and Cyrenaica during his short rule.

Media (Old Persian: 𐎶𐎠𐎭 Māda; Greek: Μηδία Mēdía; Akkadian: Mādāya) was a political entity centered in Ecbatana that existed from the 7th century BCE until the mid-6th century BCE and is believed to have dominated a significant portion of the Iranian plateau, preceding the powerful Achaemenid Empire. The frequent interference of the Assyrians in the Zagros region led to the process of unifying the Median tribes. By 612 BCE, the Medes became strong enough to overthrow the declining Assyrian empire in alliance with the Babylonians. However, contemporary scholarship tends to be skeptical about the existence of a united Median kingdom or state, at least for most of the 7th century BCE.

According to classical historiography, Media emerged as one major power of the ancient Near East after the collapse of Assyria. Under Cyaxares (r. 625–585 BCE), the kingdom's borders were expanded to the east and west through the subjugation of neighboring peoples, such as the Persians and Armenians. Media's territorial expansion led to the formation of the first Iranian empire, which at its height would have exercised authority over more than two million square kilometers, stretching from the eastern banks of the Halys River in Anatolia to Central Asia. In this period, the Median empire was one of the great powers in the ancient Near East alongside Babylon, Lydia, and Egypt. During his reign, Astyages (r. 585–550 BCE) worked to strengthen and centralize the Median state, going against the will of tribal nobility, which may have contributed to the kingdom's downfall. In 550 BCE, the Median capital, Ecbatana, was conquered by the Persian king Cyrus II, marking the beginning of the Achaemenid empire.

The Medes were an Iron Age Iranian people who spoke the Median language and who inhabited an area known as Media between western and northern Iran. Around the 11th century BC, they occupied the mountainous region of northwestern Iran and the northeastern and eastern region of Mesopotamia in the vicinity of Ecbatana (present-day Hamadan). Their consolidation in Iran is believed to have occurred during the 8th century BC. In the 7th century BC, all of western Iran and some other territories were under Median rule, but their precise geographic extent remains unknown.

Although widely recognized as playing an important role in the history of the ancient Near East, the Medes left no written records to reconstruct their history. Knowledge of the Medes comes only from foreign sources such as the Assyrians, Babylonians, Armenians and Greeks, as well as a few Iranian archaeological sites, which are believed to have been occupied by Medes. The accounts related to the Medes reported by Herodotus convey the image of a powerful people, who would have formed an empire at the beginning of the 7th century BC that lasted until the 550s BC, played a pivotal role in the fall of the Assyrian Empire, and competed with the powerful kingdoms of Lydia and Babylonia.

The Lydians (Greek: Λυδοί; known as Sparda to the Achaemenids, Old Persian cuneiform 𐎿𐎱𐎼𐎭) were an Anatolian people living in Lydia, a region in western Anatolia, who spoke the distinctive Lydian language, an Indo-European language of the Anatolian group.

Questions raised regarding their origins, reaching well into the 2nd millennium BC, continue to be debated by language historians and archeologists. A distinct Lydian culture lasted, in all probability, until at least shortly before the Common Era, having been attested the last time among extant records by Strabo in Kibyra in south-west Anatolia around his time (1st century BC).
