Answer:
fur trading
Step-by-step explanation:
Before the Europeans settled in the Calumet region, the area was inhabited by many Native Americans. It thus became essential to study these tribes in connection to the area's development over time. According to Alfred Meyer, a German writer, the first stage is "fur trading." The Native Americans used their natural resources such as animal furs in trading with different nations. It became their primary source of livelihood and it also became a popular fashion for the Europeans they traded with. Later on, it also became a cause of competition between English and French.
