Kansas Historical Society, complete Kansapedia entry, paragraphs 4–7.

Complete article reviewed, including authorship and revision metadata.
The source gives November 1880 but not an exact ratification day. Enforcement was uneven; constitutional adoption did not immediately eliminate saloons.
Official state-history synthesis supplies the sequence from organized temperance through amendment ratification and implementation.
Exact state precedent and date window are linked to a verified institutional source, citation, excerpt, and dated timeline event.
