The following events in the USA and the Wild West were chosen for this work: the Lewis and Clark expedition and the Texas struggle for independence. The Lewis and Clark Expedition (1804-1806) was the first government research expedition. She was traveling through the United States from St. Louis to the Pacific coast and back. The Texas War of Independence (1835-1836) was a war between Mexico and Texas, the result of which was the transformation of Texas into an independent republic.
President Thomas Jefferson paid particular attention to the establishment of US sovereignty over Indian-inhabited lands and the exploration of resources located in the territory transferred to the United States due to the Louisiana Purchase. Despite all the difficult conditions in which they had to conduct their expedition, the expedition members achieved their final goal – to reach the Pacific Ocean.
The arrival of American settlers in fifteen years dramatically changed the population of Texas, which could not please the Mexican government. The events of fifteen years of distrust between the Mexican government and its new citizens ended when, in 1836, after the fighting, Texas declared independence and became the Republic of Texas. The fact that there were US citizens on the territory of the newly formed republic was beneficial.
Each of the selected events made a significant contribution to the overall policy of US expansionism. They correspond to the general concept of Manifest Destiny, according to which Americans believed that God intended the United States to expand its dominance to the entire North American continent. This fact hit Latin Americans and other non-European peoples hard, which was one of the reasons for the war with Mexico over territories.
