Which theory of migration states that people settle down the West Coast to make settlements

The theory you are referring to is the "Frontier Thesis." This theory was proposed by American historian Frederick Jackson Turner in 1893.

To understand the Frontier Thesis and its explanation of westward migration settlements, let's break down how you can find information about it:

1. Start by searching for articles or books on the topic. Use search engines like Google Scholar, JSTOR, or academic databases to find scholarly sources. You can also try searching in libraries or online bookstores.

2. Look for reputable sources that discuss the Frontier Thesis and its connection to westward migration settlements. Pay attention to the author's credentials, the publication date, and whether the source is peer-reviewed or cited by other scholars.

3. Once you find a reliable source, read the relevant sections or chapters that discuss the Frontier Thesis. Take notes and highlight key points or arguments made by Turner or other scholars.

4. The Frontier Thesis argues that the existence of a frontier has been a significant factor in shaping American society and culture. Turner believed that the presence of an unsettled frontier promoted individualism, self-reliance, and democracy. As settlers moved westward, they created new settlements and communities along the West Coast and beyond.

5. The thesis also suggests that this westward expansion and settlement of the frontier played a crucial role in American history by shaping the nation's identity, economy, and political institutions.

Remember, while the Frontier Thesis is a well-known theory, it is important to critically evaluate different sources and perspectives to form a comprehensive understanding of westward migration settlements and their historical significance.
