The Erie Canal was built between 1817-1825 to connect the Hudson River to Lake Erie, making transportation of goods across New York State easier and cheaper. Its completion transformed New York City into the leading commercial center, with its population growing dramatically. Many immigrants from Europe also arrived during this time, fleeing poverty and starvation, and helped build the Erie Canal and work in northern factories. President Monroe issued the Monroe Doctrine in 1823 to prevent further European colonization of nations in Central and South America that had recently gained independence.

2. The Erie Canal

3. Up until 1800, roads were made by the wear and tear of travel by people using horses and wagons.Businessmen and merchants paid a lot of money to have their merchandise transported.

4. Clipper ships carried cargo quickly across the ocean.

5. In 1817, New York decided to build the Erie Canal from the Hudson river to Lake Erie.

6. It took 8 years to build and went across the entire state of NY.

10. The canal made it easier and cheaper for businesses to send goods across the state and country.

12. Completion of the Erie Canal inaugurated a new era in the growth of New York City, Buffalo, and numerous other communities of New York State. With the increase in goods and capital, New York City cemented its role as the leading financial and commercial center in the nation, surpassing other eastern cities such as Boston and Philadelphia.

13. Partly due to the canal, the population of New York City grew from 123,706 in 1820 to 696,115 in 1850. Large areas within and outside of the state were opened up for settlement. For many years, however, the Erie Canal served as the chief traffic artery, for both passengers and freight traveling between the Northeast and what was then the West.

14. Immigrants and Factories

15. Between 1861 and 1914 almost 30 million people came from Europe to the United States. This increase in immigration to the United States had many effects.

16. Immigrants came to New York in the 1800s from many different places and for many different reasons. English, French, and Germans fled poverty and looked for opportunity. But mostly they came from Ireland and for the simplest of reasons: they were starving to death. The potato crop was failing, and English masters were taxing away their money. America seemed their only hope.

17. Some German immigrants joined the Irish and in working the city's docks, streets, factories, and construction sites. They worked on the Erie Canal—helping further America’s growth. They also worked in the factories in the North.

18. The Monroe doctrine

19. Pres. Monroe did not want European nations to control countries in this hemisphere.

20. He did not want Central America to be controlled by Europe.

23. Several countries in South American had recently undergone revolutions against their European colonial owners and ended up with republican governments. The United States agreed with their political philosophy and did not want to see those newly free nations become European colonies again.
