Why people migrated to the new world political reasons?

There were as many motives for exploration as there were people, but the primary reason for exploration was wealth and power. Natural Resources they could either sell or exploit to make money. Things such as gold, exotic foods and spices, and trade goods. Another reason is just pure curiOSity; humans have the urge to explore the unknown. Yet another is colonization, making a fresh start in a new, hopefully fertile land.
