Please help write an English essay about the westward movement in the United States.

As early as colonial North America, it began to migrate westward. His owners are land speculators and poor people in the south and north, hoping to acquire land in the west. In order to control the restricted area of colonized people, the British government issued a notice in 1763 prohibiting immigrants from crossing the west of Appalachian mountains. The revolution shattered the independence of this clause. 1783 Britain and the United States reached a peace agreement, and Britain opened all the large Indian lands in the Appalachian Mountains west of the Mississippi River to the United States. 1830 in may, president a Jackson passed the indian removal act, and the Indians moved to the west of the Mississippi river. After that, Indian troops were sent to escort the area to the east of the Mississippi River, which made the colonial cause in this area develop rapidly. The land in the "Old Southwest" (including Kentucky, Tennessee, Alabama, Missouri, Mississippi, Arkansas and Louisiana) was occupied by slaves in major plantations and became a major cotton producing area. The colonial development of "Old Northwest" (including now Ohio, Indiana, Illinois, Michigan and Wisconsin) was carried out rapidly because of the adoption of the land law (selling public land at a low price) in 1785 and the "Quasi-state Northwest District Law" in 1787. The revolution of independence has just begun. There are thousands of French people here. In 18 10, the number of immigrants exceeded 270,000, and in 1860, it reached 6.93 million. Chicago alone has a population of10 million. Developed areas are rich in grain and aquaculture.

As early as the colonial period in North America, people began to emigrate to the west. Slave owners in the south, land speculators and poor people in the north all hope to acquire land in the west. In order to limit the colonial people to the places under their control, the British government issued a notice in 1763, prohibiting immigrants from crossing the west of the Appalachian Mountains. The revolution of independence broke this rule. 1783, Britain and the United States negotiated a peaceful settlement, and Britain opened a large area of Indian-owned land from the west of the Appalachian Mountains to the Mississippi River to the United States. 1830 In May, President A. Jackson passed the Indian Migration Act to move Indians to the west of the Mississippi River. Later, he sent troops to escort the Indians out of the area east of the Mississippi River, and the colonial cause developed rapidly in this area. The land in the "Old Southwest" (including Kentucky, Tennessee, Alabama, Missouri, Mississippi, Arkansas and Louisiana) was mainly occupied by plantation slave owners and became the main cotton producing area. The colonial development of "Old Northwest" (including Ohio, Indiana, Illinois, Michigan and Wisconsin) developed rapidly because of the land regulations (selling public land at low prices) passed by 1785 and the northwest territory regulations of 1787. At the beginning of the revolution of independence, there were only a few thousand French people here. 18 10 has more than 270,000 immigrants, and 1860 has increased to 6.93 million, and the population of Chicago alone has 1 10,000. This is a region rich in grain and developed in aquaculture.
