Answer: Annexation, war, expansion, shopping.
Explanation:
These are the essential elements of United States expansion. For this purpose, the United States annexed Texas. In 1803 the united states purchased from Lusiana from the French. In 1819, Spain thus surrendered the United States to Florida, and later, on the western borders of the continental United States, New Spain was replaced by independent Mexico. The famine for the new land was the cause of increasing conflict with Native American tribes, as well as the violent expulsion of Native Americans to areas west of the Mississippi River in 1830. Part of the American colonists also began to settle in the area under simple Mexican rule, including the city of present-day Texas.
In 1836, the settlers there started an insurgency against Mexico, and after a brief war, declared the independent Republic of Texas. In the case of Mexico, the accession of Texas to the United States led to the American-Mexican War (1846-1847). US forces defeated Mexico and forced it to hand over 42% of its territory, including California, to the Guadelupe Hidalgo Peace Treaty. On October 18, 1867, America bought Alaska from Russia and thus occupied this part of the country.
