In 1778, during the [[American Revolutionary War]], Virginian [[George Rogers Clark]] captured Kaskaskia and set up a court in Cahokia, making Cahokia an independent city state even though it was part of the British [[Province of Quebec (1763–91)|Province of Quebec]]. Cahokia (and Kaskaskia and the rest of Illinois County) officially became part of the United States by the [[Treaty of Paris (1783)]], by which the United States took over former British territory west of the Appalachian Mountains. The US soon designated this area as the [[Northwest Territory]] (and, after Ohio and Indiana became states, the [[Illinois Territory]]). Meanwhile, 105 Cahokia "heads of household" pledged loyalty to the [[Continental Congress]] of the United States.
