Reasons for opening up Spanish overseas immigrants on the new air route

The reasons why the new route opens up Spanish overseas immigrants are:

1, territorial expansion and demand for oriental products.

2. Spaniards are keen to find new resources and fertile land. These are the reasons why the new air route opened up Spanish overseas immigrants. The new sea route refers to the sea route to India, America and other parts of the world that western European countries want to explore at the turn of the century from 15 to 16.
