The period between the end of the middle ages and the present
(apex)
I need the rest of the question this is a statement
Many forerunners and founding fathers of America hailed from the East, American westward expansion was considered to be the hallmark because of many reasons. It all started when Thomas Jefferson bought Louisianan territory from France, he believed that for America to become a powerful block in the world, its west ward expansion is necessary.
There was vast and cheap availability of fertile lands in the west which could be used for erecting major factories and create employment opportunities that were mostly low paid in the east due to European restrictions.
Gold Rush in Oregon was an alluring factor for westward expansion. Environment in the west was compliant and the land was productive.
The word “imperialism” is widely used as an emotive—and more rarely
as a theoretical—term to denote specific forms of aggressive behavior on
the part of certain states against others; the concept refers primarily
to attempts to establish or retain formal sovereignty over subordinate
political societies, but it is also often equated with the exercise of any form of political control or influence by one political community over another.
hope this helps :)
