Final answer:
Spain was the Western European nation that rivaled the Ottoman Empire in power during the Renaissance, confirmed by its global influence and naval power.
Step-by-step explanation:
The Western European nation that rivaled the Ottoman Empire during the Renaissance was Spain. At this time, both Spain and Portugal led the European Age of Discovery and competed for influence and territory, both in Europe and across the oceans. Their position as leaders was confirmed by the Treaty of Tordesillas and the Treaty of Zaragoza, which divided the globe into two zones of influence. The competition in naval power and territorial expansion was indicative of Spain's stature and competition with the Ottomans. On the other hand, other Western European nations like England and France were still consolidating their power and dealing with internal conflicts, such as the Protestant Reformation, which delayed their overseas expansion. It wasn't until the fortunes of Spain and Portugal declined in the seventeenth century that other European nations, including England and France, began to claim territory and establish their influence overseas, rivaling the Ottoman Empire.
