The history of the Tairona differs from that of most other native Americans in two crucial ways.
Firstly - For some 60 years after the Spanish first arrived, and effectively enslaved the population at the base of the Sierra Nevada, the rest of the community survived relatively untouched and able to observe the newcomers. When the great conflict eventually came the Tairona had already learned enough to organise their own survival.
Secondly - the Sierra Nevada proved to be a sufficiently severe obstacle to colonisation, and so lacking in desirable resources, that the invasion was never pursued to its final conclusion. At least, not until now.
