The last four kings of Yehuda struggle under the crippling hegemony first of Egypt and then of Babylon, suffering military defeat, vassalage, humiliation, deportation, siege and torture. The sun is setting on the First Temple period and it will swiftly end in the conquest of Jerusalem and the exile of its people.
Soon after Yehoahaz becomes king, Pharaoh Nekho makes his brother Yehoyakim the king placing on him a heavy tax. Yehoyakim and the higher strata of society lead a lavish lifestyle oppressing the regular people to pay the tax and for their lifestyles - something that the prophet Yirmiyahu fights against. Despite the growing power of Babylon and despite Yirmiyahu's prophecies, the people remain indifferent and believe the Beit HaMikdash to be invicible. Yehoyakim is removed by the Babylonian king and the child king Yehoyakhin rules for a mere three months. He, the skilled laborers and the vessels of the Beit HaMikdash are taken to Babylon beginning the exile of Yehuda and creating two centers - in Jerusalem with Tzidkiyahu and in Babylon with Yehoyakhin.
