Political boundaries of 19th-century europe countries frequently changed due to ? a) social reforms and colonialism b) revolutions and nationalism c) economic depression and court decisions d) diplomacy and suffrage

The correct answer is B) revolutions and nationalism.

Political boundaries of the 19th-century Europe countries frequently changed due to revolutions and nationalism.

Small countries came and went from one territory to another due to revolutions, as it happened with Prussia and Italy. Nationalism played a key role in forming nations in that similarities in identity and race allow the formation of other countries. The French Revolution influenced many ideas that were followed by other nations. Many countries confronted the authority of the monarchy and demanded changes in politics and the economy under strong nationalist ideals. Countries formed after independence movements such as the case of Poland, Romania, and Bulgaria.

the phenomenon that would be cited as evidence of increased economic interdependence between europe and the americas is  the development of mercantilism.

this theory suggests that the wealth of a country depends on its economic assets, or capital.
