Answer:
D) the federal government and Native Americans.
Explanation:
The United States of America experienced a great period of economic prosperity from its independence in the eighteenth century to its policy of territorial expansion in the nineteenth century. The main objectives of territorial expansion resulted from the consolidation of capitalism and the need to secure raw materials and consumer markets for industrialized products.
As a result of the occupation of the western territories, the modernization of transport systems took place. Railways and steam navigation were implemented, which facilitated the movement of people and goods. The formation of belts (maize, wheat and cotton plantations) and the accentuation of cattle and pig farming also began. The United States became, especially in the nineteenth century, the largest agricultural powerhouse in the world.
With the steep growth of the US economy, especially as a result of territorial expansion and the March to the West, we must ask ourselves: What happened to the indigenous populations that occupied most of the land to the west?
Millions of Indians were decimated and exterminated, making them the largest victims of the March to the West. With the Settlement Law, the government sold the land without the permission of the true owners: the indigenous people, who inhabited this land centuries before the arrival of Europeans and settlers.
