After the cotton gin began to be grown across the entire state, the Low country citizens were able to see the need to have more ties to upcountry citizens. To recognize the importance of the upcountry to the state's economy, the state constitution was amended to allow for

Equal representation for Up Country citizens.

Explanation:

With the invention of the Cotton Gin i n 1793, the production of cotton became easily accessible and cheap. In both the Lowcountry and Upcountry there was an abundance in the growth of the cotton. Both the regions of the South Carolina saw a need for the slaves and labor after the invention of the cotton gin. The equal representation in the General Assembly was the main goal of the citizens of both the regions. It was because of this reason that the state constitution went through the process of amendment.

this isn't a question and if you're going to list things be kind and use commas.
