By the late 1730s pressure from colonial expansion produced repeated conflicts. Shawnee communities were also impacted by the fur trade. While they gained arms and European goods, they also traded for rum or brandy, leading to serious social problems related to alcohol abuse by their members. Several Shawnee communities in the Province of Pennsylvania, led by Peter Chartier, a métis trader, opposed the sale of alcohol in their communities. This resulted in a conflict with colonial Governor Patrick Gordon, who was under pressure from traders to allow rum and brandy in trade. Unable to protect themselves, in 1745 some 400 Shawnee migrated from Pennsylvania to Ohio, Kentucky, Alabama and Illinois, hoping to escape the traders' influence.
