What was the dream of Eldorado?

The dream of Eldorado was the search for a legendary city called Manoa or Omoa, which was said to be the capital of a country with fabulous amounts of gold and precious stones.
The search for Eldorado began in 1530 and ended in 1618.
The Spanish found gold in Mexico and Peru, but it was not enough to satisfy their greed for the precious metal.
The story of Eldorado was invented by the Spanish to justify their conquests and the exploitation of the indigenous peoples of the Americas.
