Who was Indian ruler who built the hanging gardens as a tomb for his wife?

The Indian ruler associated with the Hanging Gardens is often misattributed; however, the gardens are actually linked to the ancient city of Babylon, not India. The gardens were reportedly built by King Nebuchadnezzar II for his wife, Amytis of Media, to remind her of her homeland's lush green hills. In India, the Taj Mahal, built by Emperor Shah Jahan as a mausoleum for his wife Mumtaz Mahal, is more commonly associated with the theme of a grand tomb.
