By the 21st century BC, Hurrians settled the northern east parts of Syria while the rest of the region was dominated by the Amorites. Syria was called the Land of the Amurru (Amorites) by their Assyro-Babylonian neighbors. The Northwest Semitic language of the Amorites is the earliest attested of the Canaanite languages. Mari reemerged during this period, and saw renewed prosperity until conquered by Hammurabi of Babylon. Ugarit also arose during this time, circa 1800 BC, close to modern Latakia. Ugaritic was a Semitic language loosely related to the Canaanite languages, and developed the Ugaritic alphabet, considered to be the world's earliest known alphabet. The Ugaritic kingdom survived until its destruction at the hands of the marauding Indo-European Sea Peoples in the 12th century BC in what was known as the Late Bronze Age Collapse which saw similar kingdoms and states witness the same destruction at the hand of the Sea Peoples.
