Jeremiah's prophetic ministry overlapped those of Nahum, Zephanaiah, Habakkuk, Ezekiel, Daniel, and Huldah, around the time the southern kingdom of Judah went into exile after wavering between alliances with either Assyria or Egypt.
Jeremiah was dubbed "The Weeping Prophet" for good reasons: his entire adult life was spent delivering harsh, negative truth to his people, and such a life and mission invites personal attack.
It's a very biographical book, in that it continually tells of the prophet's own feelings and experiences, and the tragedy of being denied the companionship and acceptance he always wanted, and the refusal of Judah to repent.
By the world's standards he was an abject failure, but by spiritual standards he was a hero.
