This book presents a new model for understanding the collection of ancient kingdoms that surrounded the northeast corner of the Mediterranean Sea from the Cilician Plain in the west to the upper Tigris River in the east, and from Cappadocia in the north to western Syria in the south, during the Iron Age of the ancient Near East (ca. 1200 to 600 BCE). Rather than presenting them as homogenous ethnolinguistic communities like "the Aramaeans" or "the Luwians" living in neatly bounded territories, this book sees these polities as being fundamentally diverse and variable, distinguished by demographic fluidity and cultural mobility.
