What was the core business that made standard oil a horizontally integrated monopoly?

B) refining oil

just took test :)

Standard Oil started its business in 1870 by John D. Rockefeller and Henry Flagler as a corporation in Ohio. It became the largest oil refinery of its time and participated in every step of the oil process, including producing, refining,  transporting, and marketing company. To answer this question lets understand what horizontal integration means: When a company increase the production of a good via expansion or acquiring the competitors at the same level of the value chain. In this matter, Standard Oil horizontally integrated its monopoly with the refining oil, buying competitors or using aggressive pricing to destroy them.

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.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

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)

information is crucial for making good decisions
