<span>In September 1957 the school board in Little rock, Arkansas, won a court order to admit nine African American students to Central High a school with 2,000 white students. The governor ordered troops from Arkansas National Guard to prevent them from entering the school. The next day as the National Guard troops surrounded the school, an angry white mob joined the troops to protest the integration plan and to intimidate the AA students trying to register. The mob violence pushed Eisenhower's patience to the breaking point. He immediately ordered the US Army to send troops to Little Rock to protect and escort them for the full school year.

The Inca culture was one of the most developed in pre-Columbian America. Among their achievements, was their architectural ability. Inca structures were made of stone that fit together, with extraordinary stability. The buildings have survived for centuries, with no use of mortar, in areas that are prone to earthquakes and volcanic activity.
The Inca also developed calendars based on astronomical observations. Astronomers understood equinoxes, solstices and zenith passages. Numerical information, particularly for administration, was stored in <em>quipu</em> strings.
In terms of art, Inca ceramics were highly advanced, although most of their silver and gold work was melted down by the Spaniards.
They were also advanced in medicine, performing skull surgeries successfully and with high survival rates.

Proponents of the concept of free market contrast it with a regulated market in which a government intervenes in supply and demand through various methods such as tariffs used to restrict trade and to protect the local economy.
