In King Leopold's Ghost, author Adam Hochschild describes many attempts to challenge the actions of King Leopold's control in the Congo. This was to reach an international audience at the time of the 20th century. The protestors depended on a variety of writing techniques to make their case successful. For example, the use of letters addressed to officials, publications of “open letters”, newspaper articles and public speeches. These marchers were George Washington Williams, William Sheppard, Edmund Dene Morel, and Roger Casement. These protesters learned about the situation in Congo in several ways. They also had diversity in how they protested through their writing. Although Edmund Dene Morel and Roger Casement share a comparative approach. George Washington Williams was a black American. He had arrived in Congo through a path that almost seemed to have taken him through several lifetimes. He was in the U.S. Army, fought in battles, attended college, and graduated from Newton in 1874. Williams married and became a pastor. It also created a milestone in human rights literature and investigative journalism. This work is entitled Open Letter to His Majesty Leopold 2nd, King of the Belgians and Ruler of the Independent State of the Congo, by Colonel the Honorable Geo.W. Williams, of the United States of America(102). As well as submitting a statement to the Senate Foreign Relations Committee urging recognition of the International Congo Association. Williams planned to go to the Congo to gather material for his book. While Williams sailed up the great river he had time to visit Africa. When he reached Stanley Falls he could no longer contain what he had heard and seen. Then write h...... half a sheet...... inside as soon as possible, and to send reports soon” (195). Casement was nineteen when he first saw the Congo while he was working on an Elder Dempster ship. For two years he had been sending reports to the Foreign Ministry on the harsh conditions in Leopold's Congo. He spent days at Lake Tumba where rubber slavery operations were conducted. Count the number of people held hostage in a village because they did not meet their rubber quota. Casement wrote daily in his diary about the horrors he had faced during his adventure. Casement found someone to share his feelings about conditions in the Congo. He had read the writings of Edmund Morel and wanted to meet him. The two shared evidence about what they discovered in Congo. Together Morel and Casement would form an organization dedicated primarily to campaigning for justice in the Congo.
