Assyrian Democratic Organization

Assyrian Democratic Organization (ADO), (Syriac: ܡܛܟܣܬܐ ܐܬܘܪܝܬܐ ܕܝܡܩܪܛܝܬܐ‎; Arabic: المنظمة الآثورية الديمقراطية‎‎) also known as "Mtakasta/Mtakasto", founded in Syria in 1957, is the oldest Assyrian political organization in Syria. The group is part of the Syrian opposition, and the Assad regime has long banned it from political life and restricted its activities in Syria.

The ADO was established as a national, political and democratic movement having with the objectives of safeguarding the existence of the Assyrian people and the realization of its legitimate national aspirations (political, cultural, administrative) in its historic homeland.
