Rewind to the 1950s and ponder: was America’s first satellite really built by a college student? How did a small band of underappreciated Russian engineers get pictures of the moon’s far side-using stolen American film?

A History of South Sudan From Slavery to Independence


Free Download Øystein H. Rolandsen, "A History of South Sudan: From Slavery to Independence"

South Sudan is the world’s youngest independent country. Established in 2011 after two wars, South Sudan has since reverted to a state of devastating civil strife. This book provides a general history of the new country, from the arrival of Turco-Egyptian explorers in Upper Nile, the turbulence of the Mahdist revolutionary period, the chaos of the ‘Scramble for Africa’, during which the South was prey to European and African adventurers and empire builders, to the Anglo-Egyptian colonial era. Special attention is paid to the period since Sudanese independence in 1956, when Southern disaffection grew into outright war, from the 1960s to 1972, and from 1983 until the Comprehensive Peace of 2005, and to the transition to South Sudan’s independence. The book concludes with coverage of events since then, which since December 2013 have assumed the character of civil war, and with insights into what the future might hold.
