Question

1. which factor most contributed to the evolution and expansion of the trans - saharan slave trade? abolition movements in europe the mongol invasions of china labor demands of islamic empires the crusades success

Explanation:

The trans - Saharan slave trade was influenced by various factors. Abolition movements in Europe were against slavery, so they would not contribute to its expansion. The Mongol invasions of China were mainly in East Asia and had no direct connection to the trans - Saharan region. The Crusades' success was centered around the Holy Land and the Mediterranean, not the trans - Saharan area. However, the Islamic empires in North Africa and the Middle East had labor demands (for tasks like agriculture, household work, and in some cases, military service). Slaves were seen as a source of labor to meet these demands, which led to the evolution and expansion of the trans - Saharan slave trade.

Answer:

Labor demands of Islamic empires
