The territory expansion that Alexander the Great reached during his time made Greece a big trade and cultural influence that leave a legacy in places such as Egypt, Italy, Persia, Babylon and some parts of India. Through his conquest, Greece spread modern ideas for that time such as democracy to rule a nation and Greek’s culture and arts.
