how did tobacco become a cash crop for Jamestown?

Tobacco became a cash crop for Jamestown due to its high demand in Europe, particularly in England, where it was popularized as a recreational product. John Rolfe introduced a sweeter variety of tobacco in 1612, which thrived in Virginia's climate and soil, leading to a successful cultivation that generated significant profits. The profitability of tobacco incentivized large-scale farming and the establishment of a plantation economy, ultimately shaping the economic foundation of the colony. This success also led to an increased reliance on slave labor to meet the growing production demands.
