How did slavery change Rome's economy? It became the primary commodity of trade within the empire. It stiffed agricultural innovation. It integrated the empire's economic structures. It led to increased trade and sophisticated manufacturing innovations.

The correct answer is: It became the primary commodity of trade within the empire.<br /><br />Slavery had a significant impact on Rome's economy, as it became the primary commodity of trade within the empire. The vast slave trade allowed for the exploitation of human labor, which fueled the growth of industries such as agriculture, mining, and domestic service. This reliance on slave labor stifled agricultural innovation, as there was little incentive for landowners to invest in new farming techniques or technologies when they could rely on slaves to work the land. Additionally, the integration of the empire's economic structures through the use of slave labor helped to create a more centralized and efficient system of production. However, it is important to note that while slavery did lead to increased trade and some manufacturing innovations, these benefits were largely outweighed by the negative consequences of the institution.
