ユダ王国
As part of the kingdom of Judah, the tribe of Judah survived the destruction of Israel by the Assyrians, and instead was subjected to the Babylonian captivity; when the captivity ended, the distinction between the tribes were lost in favour of a common identity. Since Simeon and Benjamin had been very much the junior partners in the Kingdom of Judah, it was Judah that gave its name to the identity—that of the "Jews".
