 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.
