In 1786, the South Carolina General Assembly created Greenville
County out of what had earlier been considered as Indian Territory.
In 1789, they created Pendleton County as well from Indian Territory.
Subsequently, these counties were deemed the same as "election
districts" and their population was instructed to provide
delegates to the legislature starting with the eighth (8th) General
Assembly of January 5, 1789.
Note Bene - during the 1780s and 1790s, South Carolina created
many new "counties." Not all were given "election
district" status, and by 1800, the term "county"
was no longer in use within the state of South Carolina. What
most other states would call as counties, South Carolina called
"districts" - essentially combining a "judicial
district" with an "election district."
