Why did Atahuallpa offer the Spaniards a ransom after his capture?

Atahuallpa offered the Spaniards a ransom after his capture because he perceived the extreme avarice of his captors. Following the Battle of Cajamarca, where Francisco Pizarro and his forces ambushed and captured the Inca emperor, Atahuallpa attempted to secure his release by promising to fill a room with gold.1

The Incas subsequently brought gold and silver statues, jewelry, and art objects from throughout the empire to fulfill this request. The Spaniards melted these items down into bullion and ingots, accumulating 24 tons of gold and silver—the richest ransom ever received. Despite the fulfillment of this massive payment, the conquistadores ultimately betrayed the agreement and ordered Atahuallpa to be executed.1
