Us victory in the mexican american war in 1848
For the first one The institution of slavery contradicted the foundation of the American society because till this day people of color are still being treated horrendously due to their ancestors and their teachings to the newer generation. Also it contradicted it because Americans had their amendments but it didn’t apply to slaves .
The Cossacks is a group of Slavic people located between Ukraine and Russia that was created between the 14th and the 15th century by the emergence of 2 groups.
They played an important role in the 18th century during the Russian Empire, protecting its borders from Attacks, and participating in most of the wars.
They participated too in the Russian civil war in 1917, till they declared their independence in 1918.
We can still find Cossacks groups in Russia, Ukraine, United States, and of course other countries. They're considered as an ethnicity since 2010.
