The Hittite Kingdom, full documentary. The forgotten empire of the Hittites

The Hittites used Mesopotamian cuneiform letters. Archaeological expeditions to Hattusa have discovered entire sets of royal archives in cuneiform tablets, written either in the Semitic Mesopotamian Akkadian language of Assyria and Babylonia, 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". 

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.[citation needed]

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 was successfully excavated by Professor Tahsin Özgüç from 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 reliefs portraying the Hittite rulers and the gods of the Hittite pantheon.
