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.

the mandate of heaven or tian ming (chinese: 天命; pinyin: tiānmìng; wade–giles: t'ien-ming) is a chinese political and religious doctrine used since ancient times to justify the rule of the king or emperor of china. according to this belief, heaven (天, tian)—which embodies the natural order and will of the universe—bestows the mandate on a just ruler of china, the "son of heaven" of the "celestial empire". if a ruler was overthrown, this was interpreted as an indication that the ruler was unworthy, and had lost the mandate. it was also a common belief among citizens that natural disasters such as famine and flood were signs of heaven's displeasure with the ruler, so there would often be revolts following major disasters as citizens saw these as signs that the mandate of heaven had been withdrawn.[1]

a brief flow chart describing the dynastic cycles in imperial china on claiming to withdrawing the mandate of heaven

the mandate of heaven does not require a legitimate ruler to be of noble birth, depending instead on the just and able performance of the rulers and their heirs. dynasties such as the han and ming dynasties were founded by men of common origins. the concept is in some ways similar to the european concept of the divine right of kings; however, unlike the european concept, it does not in theory confer an unconditional right to rule, despite this being exactly the case in practicality. the mandate would in theory be a preoccupation in a ruler's lifetime, when he would hold onto the mandate and live according to heavens. intrinsic to the concept of the mandate of heaven was the right of rebellion against an unjust ruler. chinese historians interpreted a successful revolt as evidence that heaven had withdrawn its mandate from the ruler. throughout chinese history, times of poverty and natural disasters were often taken as signs that heaven considered the incumbent ruler unjust and thus in need of replacement. the mandate of heaven was often invoked by philosophers and scholars in china as a way to curtail the abuse of power by the ruler. while each dynasty was not the same, they each had a lineage that passed on the prospective ruler by order of generational descent or their priority of birth. many emperors during the imperial times would optimize to have many sons who could be candidates to fill the position after the current ruler has died. in addition heaven was thought to be of how a ruler's works and performance was, which reflected upon how favorable they would be to heaven.
