How did oil in the northeast influence power in the subregion?

Oil in the Northeast, particularly in regions like Pennsylvania and West Virginia, played a crucial role in shaping economic and political power in the subregion. The discovery and extraction of oil led to rapid industrial growth, attracting investments and boosting local economies. This newfound wealth allowed oil-producing states to exert significant influence on national energy policies and fostered the rise of powerful political figures and lobbying groups focused on energy interests. Consequently, control over oil resources became synonymous with economic prosperity and political leverage within the subregion.
