Why did people migrate to the western frontier lands?

Explanation:

Migration has been an important force in the development of America. Ever since the English settled along the banks of the James River in 1607, subsequent generations have looked beyond the boundaries of their settlements to the unsettled regions of the west. These people realized that the advancement of their civilization was dependent upon a continuous supply of mobile humans who were willing to pack their belongings and their families, to relocate to another part of the continent, to transplant their culture, and to resume life in a new environment. Since the American nation was founded and developed on the basis of this westward orientation and on a belief that God had predestined the American people to fill the nation to its natural boundaries, one can easily conclude that migration has been, and continues to be to this day, a distinct characteristic of America and its people, so much so as to earn the population the title of a "People in motion."

peasants’ war, (1524–25) peasant uprising in germany inspired by changes brought by the reformation, peasants in western and southern germany invoked   divine law to demand agrarian rights and freedom from oppression by nobles and landlords. as the uprising spread, some peasant groups organized armies. although the revolt was supported huldrych zwingli and thomas müntzerits condemnation by martain luther contributed to its defeat, principally by the army of the swabian league. some 100,000 peasants were killed. reprisals and increased restrictions discouraged further attempts to improve the peasants’ plight.

i think it would be " a" i might be wrong tho

the correct answers are the following

a proxy war which functioned as a training field for wwii

republican democratic goverment

national side, leaded by the fascist general franco

the spanish civil war took place between 1936 and 1939 and was fought after a military coup undertaken on the 17th july 1936 by a group of generals that had seceeded from the spanish republican army, under the leadership of general franco, and who aimed to expel the democractically-elected republican goverment from power.

this war became a proxy war in which european powers tested their military equipment. on one side, urss and mexico supported the left-wing republican spanish goverment, while nazi germany and fascist italy supported the national fascist side.

franco managed to win the war in 1939, with the significant contribution of the foreign military support, and became the dictator of spain until his death in 1975.
