Tiglath-Pileser I was a king of Assyria during the Middle Assyrian period. According to Georges Roux, Tiglath-Pileser was "one of the two or three great Assyrian monarchs since the days of Shamshi-Adad I". He was known for his "wide-ranging military campaigns, his enthusiasm for building projects, and his interest in cuneiform tablet collections". Under him, Assyria became the leading power of the Ancient Near East, a position the kingdom largely maintained for the next five hundred years. He expanded Assyrian control into Anatolia and Syria, and to the shores of the Mediterranean Sea. From his surviving inscriptions, he seems to have carefully cultivated a fear of himself in his subjects and in his enemies alike.
