Iroquois history starts when the Iroquois originally came to America with the other Native Americans. They may have first settled around what’s now Maryland around 1000 AD. The Iroquois didn’t call themselves “Iroquois”, which is an Algonquin insult meaning “snakes”. They called themselves the “Haudenosaunee”, meaning “people who live in longhouses.” Or they called themselves by the kind of Iroquois they were – the Cayugas, the Mohawks, the Oneida, or the Seneca, for example.
Global warm weather between 1000 and 1300 AD may have encouraged the Iroquois (EAR-oh-koi) to move northward. They moved up the Susquehanna river into what’s now Pennsylvania and New York. When the Iroquois moved north, they ran into a smaller group of Woodland nomadic people and took their land. In the 1200s AD, for instance, the Allegans controlled a trade town where two important trails crossed at the north end of Owasco Lake. It’s now the town of Auburn. Cayugas (a kind of Iroquois) drove the Allegans away and took it over.
Around 1350 AD, the warm weather ended, and the environment began a “Little Ice Age“, with colder weather. The Iroquois started to fight a lot of wars around this time. They built their villages on high ground and surrounded them with strong log walls. One of their main enemies was the Algonquin, who were trying to move further south where the weather would be warmer.
At some point around the 1400s AD, the Iroquois formed a confederacy (con-FED-ur-ah-see), which is a sort of club or organization. This was an agreement between the different groups of Iroquois – the Mohawk, the Oneida, the Cayuga, the Seneca, and the Onandaigua – to get along and fight as allies against their enemies, instead of fighting each other. Iroquois leaders recorded their agreement with wampum. Wampum was a kind of decoration made by fastening thousands of tiny seashell beads together. It was super hard to make wampum. So Iroquois people used wampum to mark very important occasions like marriages, or treaties. But wampum was also a kind of money, because it was rare and hard to get, like gold.
