After the Civil War, population expansion, railroad construction, and the disappearance of the buffalo herds heightened military tensions on the Great Plains. Several tribes, especially the Sioux and Comanche, fiercely resisted confinement to reservations. The main role of the Army was to keep indigenous peoples on reservations and to end their wars against settlers and each other, William Tecumseh Sherman and Philip Sheridan were in charge. A famous victory for the Plains Nations was the Battle of the Little Big Horn in 1876, when Col. George Armstrong Custer and two hundred plus members of the 7th Cavalry were killed by a force consisting of Native Americans from the Lakota, Northern Cheyenne, and Arapaho nations. The last significant conflict came in 1891.

On 27 June, the ICC issued arrest warrants for Gaddafi, his son Saif al-Islam, and his brother-in-law Abdullah Senussi, head of state security, for charges concerning crimes against humanity. Libyan officials rejected the ICC, claiming that it had "no legitimacy whatsoever" and highlighting that "all of its activities are directed at African leaders". That month, Amnesty International published their findings, in which they asserted that many of the accusations of mass human rights abuses made against Gaddafist forces lacked credible evidence, and were instead fabrications of the rebel forces which had been readily adopted by the western media. Amnesty International did however still accuse Gaddafi forces of numerous war crimes. On 15 July 2011, at a meeting in Istanbul, over 30 governments recognised the NTC as the legitimate government of Libya. Gaddafi responded to the announcement with a speech on Libyan national television, in which he called on supporters to "Trample on those recognitions, trample on them under your feet ... They are worthless".

The roots of Greek success in the Ottoman Empire can be traced to the Greek tradition of education and commerce. It was the wealth of the extensive merchant class that provided the material basis for the intellectual revival that was the prominent feature of Greek life in the half century and more leading to the outbreak of the Greek War of Independence in 1821.

Greek success was also favoured by Greek domination of the Christian Orthodox church.
 Who held none of the wealth in the Greek society?
