The Hittites!
The Hittites were a Bronze Age Indo-European speaking people of Anatolia. They established a kingdom centered at Hattusa in north-central Anatolia c. the 18th century BC. The Hittite empire reached its height c. the 14th century BC, encompassing a large part of Anatolia, north-western Syria about as far south as the mouth of the Litani River (in present-day Lebanon), and eastward into upper Mesopotamia. The Hittite military made successful use of chariots. By the mid-14th century BC (under king Suppiluliuma I), they had carved out an empire that included most of Asia Minor as well as parts of the northern Levant and Upper Mesopotamia. After c. 1180 BC, the empire disintegrated into several independent "Neo-Hittite" city-states, some surviving until the 8th century BC.
Their Hittite language was a member of the Anatolian branch of the Indo-European language family. Natively, they referred to their land as Hatti, and to their language as Nesili (the language of Nesa). The conventional name "Hittites" is due to their initial identification with the Biblical Hittites in 19th century archaeology. Despite the use of "Hatti", the Hittites should be distinguished from the Hattians, an earlier people who inhabited the same region until the beginning of the 2nd millennium BC, and spoke a non-Indo-European language known as Hattic.
Although belonging to the Bronze Age, the Hittites were forerunners of the Iron Age, developing the manufacture of iron artifacts from as early as the 14th century BC, when letters to foreign rulers reveal the latter's demand for iron goods.
The Hittites used cuneiform letters. Archaeological expeditions have discovered in Hattusa entire sets of royal archives in cuneiform tablets, written either in Akkadian, the diplomatic language of the time, or in the various dialects of the Hittite confederation.
Before the discoveries, the only source of information about Hittites had been the Old Testament (see Biblical Hittites). Francis William Newman expressed the critical view common in the early 19th Century, that if the Hittites existed at all "no Hittite king could have compared in power to the King of Judah...". 
As archaeological discoveries revealed the scale of the Hittite kingdom in the second half of the 19th Century, Archibald Henry Sayce postulated, rather than to be compared to Judah, the Anatolian civilization "[was] worthy of comparison to the divided Kingdom of Egypt", and was "infinitely more powerful than that of Judah". Sayce and other scholars also mention that Judah and the Hittites were never enemies in the Hebrew texts; in the Book of Kings, they supplied the Israelites with cedar, chariots, and horses, as well as being a friend and allied to Abraham in the Book of Genesis.
The first archaeological evidence for the Hittites appeared in tablets found at the Assyrian colony of Kültepe (ancient Karum Kanesh), containing records of trade between Assyrian merchants and a certain "land of Hatti". Some names in the tablets were neither Hattic nor Assyrian, but clearly Indo-European.
The Hittite kingdom is conventionally divided into three periods, the Old Hittite Kingdom (ca. 1750–1500 BC), the Middle Hittite Kingdom (ca. 1500–1430 BC) and the New Hittite Kingdom (the Hittite Empire proper, ca. 1430–1180 BC).
The earliest known member of a Hittite speaking dynasty, Pithana, was based at the city of Kussara. In the 18th century BC Anitta, his son and successor, made the Hittite speaking city of Neša into one of his capitals and adopted the Hittite language for his inscriptions there. However, Kussara remained the dynastic capital for about a century until Labarna II adopted Hattusa as the dynastic seat, probably taking the throne name of Hattusili, "man of Hattusa", at that time.
The Old Kingdom, centred at Hattusa, peaked during the 16th century BC. The kingdom even managed to sack Babylon at one point, but made no attempt to govern there, enabling the Kassite to rise to prominence and rule for over 400 years.
During the 15th century BC, Hittite power fell into obscurity, re-emerging with the reign of Tudhaliya I from ca. 1400 BC. Under Suppiluliuma I and Mursili II, the Empire was extended to most of Anatolia and parts of Syria and Canaan, so that by 1300 BC the Hittites were bordering on the Egyptian sphere of influence, leading to the inconclusive Battle of Kadesh in 1274 BC.
Civil war and rivalling claims to the throne, combined with the external threat of the Sea Peoples weakened the Hittites and by 1160 BC, the Empire had collapsed. "Neo-Hittite" post-Empire states, petty kingdoms under Assyrian rule, may have lingered on until ca. 700 BC, and the Bronze Age Hittite and Luwian dialects evolved into the sparsely attested Lydian, Lycian and Carian languages.
Remnants of these languages lingered into Persian times (6th–4th centuries BC) and were finally extinguished by the spread of Hellenism which followed Alexander the Great's conquest of Asia Minor in the 4th century BC.
The script on a monument at Boğazköy by a "People of Hattusas" discovered by William Wright in 1884 was found to match peculiar hieroglyphic scripts from Aleppo and Hamath in Northern Syria. In 1887, excavations at Tell El-Amarna in Egypt uncovered the diplomatic correspondence of Pharaoh Amenhotep III and his son Akhenaton. Two of the letters from a "kingdom of Kheta"—apparently located in the same general region as the Mesopotamian references to "land of Hatti"—were written in standard Akkadian cuneiform script, but in an unknown language; although scholars could read it, no one could understand it. Shortly after this, Archibald Sayce proposed that Hatti or Khatti in Anatolia was identical with the "kingdom of Kheta" mentioned in these Egyptian texts, as well as with the biblical Hittites. Others such as Max Müller agreed that Khatti was probably Kheta, but proposed connecting it with Biblical Kittim, rather than with the "Children of Heth". Sayce's identification came to be widely accepted over the course of the early 20th century; and the name "Hittite" has become attached to the civilization uncovered at Boğazköy.
During sporadic excavations at Boğazköy (Hattusa) that began in 1906, the archaeologist Hugo Winckler found a royal archive with 10,000 tablets, inscribed in cuneiform Akkadian and the same unknown language as the Egyptian letters from Kheta—thus confirming the identity of the two names. He also proved that the ruins at Boğazköy were the remains of the capital of an empire that at one point controlled northern Syria.
Under the direction of the German Archaeological Institute, excavations at Hattusa have been underway since 1907, with interruptions during both wars. Kültepe has been successfully excavated by Professor Tahsin Özgüç since 1948 until his death in 2005. Smaller scale excavations have also been carried out in the immediate surroundings of Hattusa, including the rock sanctuary of Yazılıkaya, which contains numerous rock-cut relief's portraying the Hittite rulers and the gods of the Hittite pantheon
The Hittite kingdom was centred on the lands surrounding Hattusa and Neša, known as "the land Hatti" (Ha-at-ti). After Hattusa was made capital, the area encompassed by the bend of the Halys River (Turkish: Kızılırmak, which Hittites called the Marassantiya) was considered the core of the Empire, and some Hittite laws make a distinction between "this side of the river" and "that side of the river", for example, the reward for the capture of an eloped slave after he managed to flee beyond the Halys is higher than that for a slave caught before he could reach the river.
To the west and south of the core territory lay the region known as Luwiya in the earliest Hittite texts. This terminology was replaced by the names Arzawa and Kizzuwatna with the rise of those kingdoms. Nevertheless, the Hittites continued to refer to the language that originated in these areas as Luwian. Prior to the rise of Kizzuwatna, the heart of that territory in Cilicia was first referred to by the Hittites as Adaniya. Upon its revolt from the Hittites during the reign of Ammuna, it assumed the name of Kizzuwatna and successfully expanded northward to encompass the lower Anti-Taurus mountains as well. To the north lived the mountainous people called the Kaskians. To the southeast of the Hittites lay the Hurrian empire of Mitanni. At its peak during the reign of Mursili II, the Hittite empire stretched from Arzawa in the west to Mitanni in the east, many of the Kaskian territories to the north including Hayasa-Azzi in the far north-east, and on south into Canaan approximately as far as the southern border of Lebanon, incorporating all of these territories within its domain.
