When one country controls another negative and positive things happen. I think the world will change because the two countries will start to fighting with each other to who owns the land or country. The good things that will happen will be the country will be able to get more land, crops, food which I think is very important to have in a country. Also the country can learn more things such as religions. The bad things are if it turns into a fight then some people will die and the population will go down and there might not be much people in the country.
