Explanation:

During the Islamic Golden Age, the Muslim world was thriving in all aspects, including the sciences. Europe, on the other hand, was trapped in the Dark Ages, stagnating and even regressing because of the rule and limitations set by the Catholic Church. The Muslim Caliphates were one of the most advanced in the world at their prime, and they had invested a lot in the sciences, which resulted in the emerging of numerous scholars and innovators that managed to create new technologies that were much more advanced. One of those technological advancements was a device called astrolabe. This device revolutionized the sea travel and trade, making it much more easy for orientation, and making it quicker and more efficient because of it. The European managed to get their hands on this device, and they started to use it immediately, and in the centuries that followed it was crucial for their explorations, discoveries, and conquests of new territories.
