A key factor in the society being effective is the rules or laws of marriage. The Natchez tribe consisted of 900 people. The highest rank is the Sun, which consisted of 100 people, then came the noble, which be composed of 200 people. Then came the honoreds, which had 200 and last is the Stinkards, which consisted of 400 people. Marriages were only permitted among people only in certain combinations. For example, the male Stinkwards were limited to marry only a small percent of women in other groups. While the female Stinkwards weren't as limited as the men. Furthermore in the beginning of these marriage laws, everyone found a mate, so the population didn't change but the distribution among the classes changed. However, as years passed, the population declined because of the awkward marriage rules. For example, as the year passed, the distribution among people in the groups changed and suddenly their was not any more Stinkwards, so some people couldn't marry. This was a major problem for the Natchez Indians. (http://www.maxwell.syr.edu/maxpages/faculty/jbennett/651s01/natchez2.html, 9-16-03).
Mounds were very important to the Indians; they used it for religious and community events. Mounds were very hard to make because they could of have been 26 feet across and 4 feet high. Mound building started around the 13 century and only a few high-ranking tribal officials lived at the mound on a day-to-day basis. The people of the tribe spread over a wide area on family farms, and gathered at the mound centers periodically for social and religious activities. For example, some Frenchman wrote about how the Indians used human sacrifice to please the gods. One of the most important mounds was the Emerald Mound, near what is now Natchez Trace Parkway. Archaeological evidence says that Emerald Mound may of have been the main ceremonial mound center for the tribe before that place was shifted to the Grand Village sometime before to the arrival of French explorers in the late 1600s.
