Native Americans and Settlement in the Chicago Region

Geographical Context
- Permanent villages primarily along rivers; seasonal use of lake plain (present-day Chicago).
- Evidence of human habitation for thousands of years, likely hunters following large animals as glaciers receded.
Early Subsistence
- Small human populations engaging in hunting and gathering.
- Development of settled communities around 2000 years ago, integrating agriculture with natural resources (fish, shellfish, game).
Cahokia Mounds
- Example of significant societal development; large mound-building civilization in Illinois, reflecting advanced societal structures.
Impact of European Arrival
- Catastrophic for native populations due to diseases (smallpox, measles) leading to community collapses.
- Conflicts emerged as displaced tribes, like the Illini, were further marginalized. By 1800, the Illini largely vanished as a distinct group.
Potawatomi Lifestyle
- Settled in the Chicago region by the 1830s; small populations (~thousands).
- Seasonal habitation: wooden houses in spring and summer, winter hunting camps.
- Major crops included corn, beans, and squash.
Cultural Practices
- Spring maple sugaring as a communal event; maple sugar used similarly to salt.
- Extensive use of fire as a land management tool; maintained diverse ecosystems.

Jean Baptiste Point du Sable
- Established trading post at the Chicago River mouth; traded with natives using iron pots, steel, and blankets.
- Cultural interconnectivity between Native Americans and European traders.
Post-War of 1812 Changes
- Increased American settlement in the Chicago region; systematic land surveying initiated.
- Rapid population growth (from 350,000 in 1870 to over 1 million before 1900).
Environmental Changes
- Fire suppression led to changes in natural landscapes; loss of prairies, rise of oak woods.
- Changes in land use due to agricultural practices introduced by settlers; erosion of natural biodiversity.

Urban and Suburban Expansion
- Chicago's population peaked in the 1950s; trend towards suburbanization began.
- Development favored by federal policies post-World War II; emergence of suburban neighborhoods.
- Changes in commuting patterns due to interstate highways.
Manufacturing Shifts
- Deep job losses (>100,000 in manufacturing over 30 years); industrial areas like Gary faced population decline while suburban areas thrived.
- Urban sprawl caused fragmentation of natural habitats, impacting regional wildlife.

Urban Sprawl Effects
- Excessive development outpaced population growth, converting farmland rapidly to residential and commercial properties.
- Changes in flora and fauna (e.g., population booms in raccoons and white-tailed deer due to urbanized areas).
- Ongoing challenges in preserving natural areas amidst suburban expansion and land development.
