The Story-

One legend associated with Buddha says that the night before his mother gave birth to him, she dreamed of a white (albino) elephant giving her a pure lotus flower. Thus, white elephants have historically been considered sacred in Thailand (which used to be called Siam). All white elephants were therefore the property of the King of Siam.

Since they were sacred, white elephants were not allowed to do any work. They had to be well-cared for, and they required a tremendous amount of resources to maintain. All white elephants were given great honor by the people.

If the King of Siam was pleased with one of his courtiers, he would give him a white elephant, along with money, land, and servants to take care of it. However, if the King was displeased with one of his courtiers, he would give him a white elephant, with no land or money to help take care of it. The courtier would then be required to care for the sacred white elephant out of his own resources. Since the elephant was sacred, the unfortunate courtier could not even put it to work in order to help earn money for its care. Because of the large amount of money required to care for the elephant, the courtier would soon be financially ruined and dishonored.

That is how the phrase "white elephant" came to mean "an unwanted gift."
