How did european voyages of exploration lead to european empires in the eastern hemisphere?

It started when Ferdinand Magellan a Portuguese explorer wanted to prove that the earth was round. In response to hisSpanish expedition, he was successful to prove his theory -arriving at Homonhon island of the Philippines. hence, this is where the voyages started to sequence their turns to find the Spice Islands, though Magellan was also a pioneering explorer to this cause, traveling to Asia. As the Westerns travelled around the globe to the continents of Asia. They found the rich resources it contains. With their ulterior motives illustrated as “God, Glory, God”. In this simple mantra explains the European expeditions urge to conquer the Eastern hemispheres by acquiring the goods and resources in many of the Asian islands. Until they were able to build their empire in these islands.
