Find out the discovery of new sea routes during 15 to 17 century

approximately from the beginning of the 15th century until the end of the 18th century), is an informal and loosely defined term for the period in European history in which extensive overseas exploration emerged as a powerful factor in European culture and which was the beginning of globalization. It also marks the rise of the period of widespread adoption in Europe of colonialism and mercantilism as national policies. Many lands previously unknown to Europeans were discovered by them during this period, though most were already inhabited. From the perspective of many non-Europeans, the Age of Discovery marked the arrival of invaders from previously unknown continents.

Global exploration started with the Portuguese discoveries of the Atlantic archipelagos of Madeira and the Azores in 1419 and 1427, the coast of Africa after 1434 and the sea route to India in 1498; and from the Crown of Castile (Spain), the trans-Atlantic voyages of Christopher Columbus to the Americas between 1492 and 1502 and the first circumnavigation of the globe in 1519–1522. These discoveries led to numerous naval expeditions across the Atlantic, Indian and Pacific oceans, and land expeditions in the Americas, Asia, Africa and Australia that continued into the late 19th century, and ended with the exploration of the polar regions in the 20th century.
