Daughter of Achav, king of Israel, and Izevel, the Sidonian princess (2 Kings 8:18, 26)
Married Yoram, king of Yehudah (2 Kings 8:18, 2 Chronicles 21:6)
Mother of Achazyahu, who reigned only one year before being killed by Yehu during his purge of the house of Achav (2 Kings 9:27)
Upon hearing of her son's death, 'arose and destroyed all the royal seed of the house of Yehudah' (2 Kings 11:1, 2 Chronicles 22:10) — the single closest the Davidic line ever came to total extinction
Yehosheva (Yehoshava), Achazyahu's sister, secretly took the infant Yoash and hid him in the Temple for six years (2 Kings 11:2–3, 2 Chronicles 22:11)
Reigned over Yehudah for six years (2 Kings 11:3) — the only woman to rule Yehudah in her own right, and the only break in unbroken Davidic-line succession before the exile
In the seventh year, Yehoyada the priest crowned the seven-year-old Yoash; Atalyah, hearing the celebration, cried 'Treason! Treason!' and was put to death at the horse entrance to the palace (2 Kings 11:4–16, 2 Chronicles 23)
“She arose and destroyed all the royal seed of the house of Yehudah — the line's closest brush with extinction”
Traditional note: FLAGGED: Atalyah is not named in Matthew 1's genealogy, which reads '...Joram begat Uzziah...' (Matthew 1:8), skipping Achazyahu, Yoash, and Amatzyahu entirely; see the note on 'achazyahu-melech-yehudah' for Matthew's compression. She is included in this dataset despite her absence from Matthew because of her unique and central role in the Messianic line's narrative: her six-year usurpation (2 Kings 11) is the only interruption to direct father-to-son Davidic succession before the Babylonian exile, and her attempted massacre of 'all the royal seed' is the closest the line ever came to extinction prior to Yeshua. 'tribe' is set to 'outsider' as a judgment call: she is technically of the northern dynasty (her father Achav reigned over Israel) rather than a non-Israelite in the strict sense, but her mother Izevel was an explicitly foreign (Sidonian) princess (1 Kings 16:31), and her narrative function in this dataset — an outsider whose line nearly displaces David's — is the inverse of Rahav/Ruth/Tamar/Naamah's 'outsider who joins positively'. 'father': 'achav' and 'mother': 'izevel' are forward references to the planned Batch 5 entries for Achav and Izevel (per hebroni-tree-illustration-priorities.md); they do not yet exist in this dataset.
