ORIGIN & HISTORY

About the name

Caspian Sea (English exonym); ultimately from the Caspi/Cas, an ancient Transcaucasian tribe. The Caspian Sea's name preserves the memory of the Caspi, an ancient Transcaucasian people recorded by the geographer Strabo as already extinct in his time ('the tribe has now disappeared'), with the sea and surrounding region (Caspiane) the only lasting trace of them.
