Aramaic alphabet
The ancient Aramaic alphabet was used to write the Aramaic languages spoken by ancient Aramean pre-Christian peoples throughout the Fertile Crescent. It was also adopted by other peoples as their own alphabet when empires and their subjects underwent linguistic Aramaization during a language shift for governing purposes — a precursor to Arabization centuries later — including among the Assyrians and Babylonians who permanently replaced their Akkadian language and its cuneiform script with Aramaic and its script, and among Jews (but not Samaritans) who adopted the Aramaic language as their vernacular and started using the Aramaic alphabet, which they call "Ktav Ashuri", even for writing Hebrew, displacing the former Paleo-Hebrew alphabet.
