As the country achieved eventual independence and then added to its territory, finally completing Manifest Destiny in 1848, you could say there were any number of direct effects on the United States, though they were over time, and not so much revealed in just a few events.

For example, once the British Empire and the colonies won the French and Indian War, they added territory to the western frontier that, after independence, would become American land and open for settlement.  The Louisiana Purchase in 1803 doubled the size of the country, and all of this available land became a long term magnet for immigrants interested in getting their own farmland.  So the agricultural output of the US steadily increased into the 19th century and so did the population.

Adding western land also led to massive cotton plantations, so another effect of acquiring new territory was an increase in the slave population as well, and the sectional tension between north and south that resulted.

From 1763 to 1852, when the Gadsden Purchase was completed, the population of the US had increased from 1.5 million to 27 million.
