Integration of the high school in little rock finally happened when

In 1957, a federal court ordered integration in Little Rock, Arkansas, public schools. Nine black children were selected for admission to Little Rock Central High School, but local police, by decision of the state governor Faubus, did not allow them to attend classes. After the Little Rock crisis attracted media attention and sparked an international outcry, President Dwight Eisenhower sent federal troops to Little Rock. On September 24, 1,200 soldiers from the 101st Airborne Division from Fort Campbell, Kentucky, were brought into the city. Soldiers accompanied the children on their way to school and guarded them in the corridors. To deprive Governor Faubus of the opportunity to continue to impede integration, the president reassigned the entire 10,000th Arkansas National Guard to Washington. From that moment, African American children began to attend classes.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
