[1] The eponymous dynasty founder was Baasha of Israel, son of Ahijah and member of the Tribe of Issachar.
During this period, the Books of Kings mention 9 occasions where the throne of the kingdom was captured by usurpers.
Among these 9 usurpers, only Omri and Jehu managed to establish relatively stable and long-lived dynasties.
This explains why the usurpers had to eliminate the heirs of the previous dynasties, in an effort to solidify their own hold on the throne.
[2] Baasha seems to have orchestrated his coup d'état at a time when the House of Jeroboam was relatively weak, following unsuccessful wars against Shishak and Abijah of Judah, and territorial losses.
[2] The fall of the House of Baasha seems to have been a consequence of their own military weakness, as it followed lost unsuccessful wars against Asa of Judah and Ben-Hadad I.
[2] In the narrative of the Books of Kings, new and inexperienced monarchs often had to face prospective usurpers in the early years of their reign.
