What was the most significant factor that drove the expansion of slavery in the Southern colonies?

• A. The rise in cotton production
• B. The demand for labor-intensive crops like rice and tobacco
• C. The introduction of new agricultural technologies
• D. The influx of European immigrants

Answer: (B)

The most important factor shaping how slavery grew in the Southern colonies was the enormous labor demand created by labor-intensive cash crops. Plantations grew crops like rice in the coastal areas of South Carolina and Georgia, and tobacco in Virginia and Maryland, which required a steady, large, and often skilled workforce. Enslaved Africans provided the needed labor, making slavery a financially essential system for these economies. While cotton later became dominant in the 19th century, its rise is outside the main period of 1607–1803, and the expansion during these years is best explained by the economic need to farm these demanding crops. European immigration did add workers in some spots, but enslaved Africans remained the core labor force on these plantations, driving the growth of slavery itself.
