Akey element of the compromise of 1850 was

The Compromise of 1850 was an effort to preserve the balance between slave states and free states and keep the union together in the United States.

Explanation:

The Compromise of 1850 was passed after an attempt to have all new territories be non-slave states.  In 1846, Congressman David Wilmot of Pennsylvania introduced an amendment to an appropriations bill, stipulating  that any territory gained from Mexico (after winning war vs. Mexico) would be free, not allowing slavery.  [Don't think of Wilmot as an abolitionist, though.  He wanted new territories to be free of blacks, preferring whites-only territories.]   Wilmot's amendment passed in the House of Representatives, but was unable to get approval in the Senate.  The Compromise of 1850, a package of five bills passed by Congress in September of that year, sought to accommodate some of the issues both South and North were debating  during those years.  The balance between slave states and free states continued to be an issue.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)

the conditions that made the byzantine empire vulnerable to attacks by the muslin turks were the sack of constantinople by western crusaders, the conquests of the sultanate of rum, presence of rival kingdoms and finally the set up of fiefdoms at the empire which were owned by the ghazis (turkish warriors).
