The United States changed so many things from 1770 to 1870. The population
increased drastically, from 2,148,100 in 1770 to 38,558,371 in 1870. The increase
in population is caused by immigration of people to the US and slavery was
another cause. Slavery and population had a big affect on the next 100 years of the
United States history. The US also changed diversely with new innovations like
roads, waterway, railroads, steamboats, and refrigerated railroad cars.
A few innovations that changed or improved from 1776 to 1870 are the roadways,
waterways, railroads, steamboats, and refrigerated railroad cars. Roadways were in
innovation that created a way for easier, and faster transportation. Waterways were
also a way for transportation, to cut out a lot of land, and cut out time. Waterways
are a faster way for trade and barter. Steamboats were what pioneers used to travel
down the waterways to trade and sell goods. Railroads were still used for closer
travel, with items that did not need to get there as fast as possible, because railroad
cars do not move very fast, although the steam engine improved the speed f
The most important event was obviously the American Civil War from 1861-1865
this led to the 14th amendment which defined a citizen as” any person born or
naturalized in the US.” The 13th amendment abolished slavery, and the 15th
amendment prohibits denying the right to role to someone because of their race.
Other key events include the Louisiana purchase, the Texas revolution. The
Spanish American war, the of 1812, the purchase of Alaska, the Mexican cession.
The Indian wars, and the California Gold Rush. The right to vote way extended to
all male’s citizens by the 15th amendment. Women were not given the right to vote
until the 19th amendment was passed in 1920.
