According to the Encyclopaedia Britannica:
Nebuchadrezzar II "the second and greatest king of the Chaldean dynasty
of Babylonia (reigned c. 605-c. 561 BC) He was known for his military
might, the splendour of his capital, Babylon, and his important part in
Jewish history. Nebuchadrezzar II was the oldest son and successor of
Nabopolassar, founder of the Chaldean empire. He is known from cuneiform
inscriptions, the Bible and later Jewish sources, and classical authors.
His name, from the Akkadian Nabu-kudurri-usur, means "O Nabu, watch over
my heir." ...Little is known of his family life beyond the tradition
that he married a Median princess, whose yearning for her native terrain
he sought to ease by creating gardens simulating hills. A structure
representing these hanging gardens cannot be positively identified in
either the cuneiform texts or the archaeological remains. Despite the
fateful part he played in Judah's history, Nebuchadrezzar is seen in
Jewish tradition in a predominantly favourable light."
