In 1453, Constantinople was captured by Tusks and they called it Istanbul. You have to know this time Constantinople is a road that connect Europe with Middle East and Asia so this place is clearly important for trading. But Tusks isolated Istanbul and they did let anyone go thorough this place
==> European has to find a new way to come to Asia.
And Because of the Technological Revolution such as:
I/ The Caravel ( developed by Portuguese  1400s):
– It is a ship
– it developed because of the background The Galley
This is a Galley (8,000 year) Untitled drawing (3).jpg

It has some problems: 1/ Lack of cargo space because it has many sailors inside.

2/ Flat- bottomed.

This is a Caravel:untitled-drawing-4

Pros of Caravel:

1/ Rounded Bottom

2/ Wind – powered

3/ Carry more cargo

4/ Half of Garley crews

5/ Travel Ocean and Sea

II/ Magnetic Compass: invented in China

III/ Astrolabe: invented by Indian.untitled-drawing-5
