Answers may vary depending on the timeline but the European expansion was originally done for three main reasons. These reasons are commonly known as the three G’s or gold, glory and God. The Europeans wanted to look for more riches such as gold, spices and other resources. To meet such needs, it was necessary for them to sail across countries. In their travels, they also preached about religion. The word ‘glory’ represents their need for power by colonizing new lands.
