How have states made their highest amounts of revenue in the past?

Historically, states have generated their highest revenues through a combination of taxation, natural resource extraction, and federal grants. Income taxes, sales taxes, and property taxes have been primary sources of revenue, while states rich in Natural Resources, like oil or minerals, often see significant income from extraction taxes. Additionally, federal funding has provided substantial financial support for various state programs and infrastructure. Economic growth, population increases, and changes in tax policy have also influenced state revenue fluctuations over time.
