1) The Platt Amendment declared Cuba a U.S. protectorate.
U.S. involvement in Cuba resulted from the U.S. defeat of Spain in the Spanish-American War of 1898. Cuba had to meet a series of conditions in order for U.S. troops to withdraw from Cuba.
2) Monroe Doctrine declared that an act by a European power in the Western Hemisphere would be considered a threat.
Proposed by Monroe in 1823? (check me on this) from lessons learned after the War of 1812 and continued British meddling in North America.
3) Roosevelt's Corollary set up the United States as a Latin American police force.
This was Roosevelt's famous "Speak Softly and Carry a Big Stick" policy. The world tour of the U.S. Navy's Great White Fleet is also a good example of the Roosevelt Corollary. U.S. troops were sent to various Latin American countries in the early 20th century (Nicaragua, Dominican Republic, Haiti, etc.) when U.S. business interests were threatened.
4) Panama Canal reduced time and expense of U.S. global trade by shortening shipping route between the Atlantic and the Pacific.
One of the most important engineering feats of the 20th century.
They are real. Just extinct now.
Bleeding Kansas refers to the border war between Pro-Slavery and Anti-Slavery citizens. It took place on the Kansas/Missouri border.
Hey there!
Unlike in Athens:
In Sparta, stealing was completely encouraged. People fought for food daily. Also, it was an oligarchy, and lots of people didn't have voting rights. Who could was a very selective and specific process. Additonally, women had more rights than in most other Greek city states, and could even own their own land. Boys had to fight people in barracks for usually over a decade, and then had to serve in the army.
Unlike in Sparta:
In Athens, boys were given a classical education and girls were left at home with their mothers to learn about how to take care of a family. A classical education included things like arithmetic, space, science, art, music, and much more. Boys, when they became adults, had to serve in the army for a short period of time, but then they could quit and then do what they desired with their lives.
Hope this helps!
