On the slave front Michelle, it was part of the Polynesian culture to enslave conquered peoples. The Masters and Servants Act of 1850 replaced the Kingdom's "Kauwa System" of serfdom. The word "kauwa" is Hawaiian for "slave-class." Their slave-class, called the "kauwa", were filled with those taken as prisoners of war or their children. The kauwa were identified with a tattoo mark around the eyes, or on the forehead.
They were indeed slaves, but also much more than that was that they were often used as human sacrifices at the luakini heiau when worshipping the gods.
For the average person Hawaii was anything but paradise.
