Conflict and cooperation among groups and organizations influence the development of the world because?

The history of the world consists of how different groups of people divided, organized and unified. Competing for control is a social characteristic that resulted in cooperation and conflict between groups.

After centuries of developing countries have organized themselves and now we have a primary political division of the Earth that is by state sovereignty. A big example of cooperation among groups of countries is the United Nations, that unite countries to solve problems and help each other.

Also, there were Regional Alliances among nations for the military - NATO for example - political or economic reasons, for example, Europe Union, MERCOSUL and others.

There are bad results from conflicts among different groups or nations, such as wars, terrorist attacks, urban riots, and other problems. But mostly we can see that we have more profits from cooperation than problems with conflicts. There is no country in the world that is 100% self-sufficient in all products, all countries need to import something and export something and this creates a good environment that avoids world conflicts and helps to solve regional ones.

the expansion of the rule of empires over other territories took place as a result of several reasons including economic, ethnocentric, political, and religious, and exploratory purposes.

in terms of economic purposes: imperial governments aimed to maximize profits and with that purpose they neeeded cheap labor, access to or control of markets to sell or buy products. they also desired to find natural resources (precious metals and land). in the awake of   industrial revolution, dependent colonies provided the necessary raw materials that european factories and market needed to manufacture products.  

ethnocentric: many territories were conquered by imperial territories in an attempt to spread their cultures, values and belief as they considered them to be superior. in the late 19th century, for example, european powers held   the racist belief that inferior races should be conquered in order to “civilize” them.

political: another reason that drove conquer and expansion was patriotism and growing imperial power. it refers to national prestige, pride, and security. empires sought strategic territory to ensure access for their navies and armies around the world.

religious: the aim of converting new member of other religions was another factor that prompted expansion.   christian missionaries from europe established churches in conquered territories during the nineteenth century. thus, they spread western cultural values. furthermore, the imperial nation’s language was spread as well, through educational and religious interactions.

exploratory: imperial nations or their citizens aimed to explore territory that was unknown to them,   for different purposes including medical or scientific research, however, at the very   beginning, they did it to embark on adventure. furthermore, imperial explorers sought to discover, map, and claim territory before their imperial competition did, for national and personal glory as well as to realize the imperialist goal of expansion.
