Cotton factors were agents or brokers who facilitated the sale and export of cotton, acting as intermediaries between cotton growers and buyers, particularly in the 19th century. They played a crucial role in the rise of the cotton economy by managing transactions, negotiating prices, and ensuring that cotton from Southern plantations reached domestic and international markets. Cotton factors not only influenced the pricing and distribution of cotton but also shaped the plantation system's dynamics, as they relied on a network of planters for supply.
