In what ways do the civilizations of china, europe, and the islamic world in the fifteenth century seem to be moving in the same direction, and in what respects were they diverging from one another?

- All of these three civilizations continued to develop more political and governmental unity. 
- China and Europe were looking back to their roots, Europe grew them a little further, and China turned back to them. 
- Islam and Europe both worked to expand their religions, and to grow their land land and control. China did not. 
- China and Europe both started to explore the water, for different reasons though. Europe gained more by finding the Americas.
- Islam was split into four parts, a little similar to Europe's fragmented states. China was a completely unified empire.
Please put me as brainlest if this is right!

Population growth is one way
