What was one of the primary benefits of the spread of horses throughout Eurasia?

The spread of horses throughout Eurasia had a significant impact on military capabilities, making this option the most appropriate choice. Horses greatly enhanced the mobility and effectiveness of armies, allowing for faster troop movements, more efficient communication, and the ability to cover vast distances quickly. This increased mobility facilitated the expansion and consolidation of empires, as mounted warriors could outmaneuver foot soldiers and engage in swift raids or defensive actions.

Additionally, the introduction of cavalry units changed warfare dynamics, leading to strategies that capitalized on the speed and agility of horse riders. Different cultures that adopted horses often had their military success tied directly to this innovation, leading to shifts in power across the continent.

While improved agricultural methods, expansion of artistic expression, and development of complex political structures were also influenced by the movement of goods and ideas—factors that could include the use of horses—the primary and most direct benefit linked to the spread of horses specifically aligns with enhanced military capabilities.
