text: The first "westerners" to contact native Marquesas were Polynesians from Tahiti who immediately engaged in ethnic cleansing and genocide. 
  
  What you define as "Hawaiians" then began exterminating each other as epitomized by Battle of Nuʻuanu.  Interesting to note that little notice was taken of the iwi resulting from the Kalelekaʻanae. No state subsidized cultural practitioners in 1795?
  
  As for "ummmm What do you think Hawaiians did before western contact?"
  
  Based upon input from self-appointed experts the primary activities were:
  
  1) mmmmm... Chanting reverently to inanimate objects.
  
  2) Disfiguring each other with kakau, using unsanitary implements due to their lack of knowledge about animate beings such as bacteria and pathogens.
  
  3)  Deforestation to create war implements and surfboards. 
  
  4)  Growing kalo containing xalic acid which causes kidney stones. 
  
  As for organizational skills the 2106 'Aha and the associated Na'i Aupuni with its 191 participants is epitomizes them.
