Question: What were the nations after 1722 that composed a culture that was extensively studied by William N. Fenton?

 They were known during the colonial years to the French as the "Iroquois League," and later as the "Iroquois Confederacy," and to the English as the "Five Nations" (before 1722), and later as the "Six Nations," comprising the Mohawk, Onondaga, Oneida, Cayuga, Seneca, and Tuscarora peoples. The Iroquois ( or ) or Haudenosaunee ( ) are a historically powerful northeast Native American confederacy. <SEP> William N. Rhodes was an American airforce Technical Sergeant in World War II.  On March 31, 1945, TSgt.  William N. Rhodes' aircraft was engaged in a mission to take out a primary target (oil refinery) at Ziet, Germany.  During that engagement his B-17 aircraft was hit by enemy fire.  The number three engine oil supply line was cut by flak, and the landing gear was hit and jammed.  Flak also damaged an engine housing causing that prop to be shut down and feathered.  The Aircraft was able to maintain an altitude of 17,500 feet and began its journey back to England when two jet propelled German fighters attacked.  These two German aircraft were sighted and immediately reported to the pilot by TSgt.  Rhodes.  The B-17 was hit during the German fighter attack inflicting extensive damage to the aircraft's number three fuel tank, causing it to explode and tossed the right wing violently.  Following this hit the aircraft went into a tight downward spin, within just a few thousand feet the tail section of the aircraft blew off causing the aircraft to level off slightly and continue falling in a shallow spin.  This presented the opportunity for the Navigator, Turret Gunner, Co-Pilot and TSgt.  Rhodes to bail out.  TSgt.  Rhodes and three other crew members landed near Biberach, Germany.  Of the nine original crew members on the B-17, only four survived the aerial encounter.  Upon landing, TSgt.  Rhodes and the other survivor’s were captured by German troops waiting on the ground, searched and taken to a Luftwaffe camp where they were processed as Prisoners of war. <SEP>  He started his studies of the Iroquois in the 1930s and published a number of significant works over the following decades.  His final work was published in 2002.  During his career, Fenton was director of the New York State Museum and a professor of anthropology at the State University of New York. William N. Fenton (December 15, 1908 – June 17, 2005) was an American scholar and writer known for his extensive studies of Iroquois history and culture. <SEP> The Ashanti (also spelled Asante) Empire (1701–1957) was an Akan empire and kingdom in what is now modern-day Ghana.  The Ashanti Empire expanded from Ashanti to include the Brong-Ahafo, Central region, Eastern region, Greater Accra region, and Western region, of present-day Ghana.  The Ashanti benefited from early firearm adoption.  Combined with effective strategy, they fashioned an empire that stretched from central Ghana to the present-day Ivory Coast.  Due to the empire's military prowess, wealth, architecture, sophisticated hierarchy and culture, Ashanti has been extensively studied and has more historiographies by European, primarily British, authors than almost any other indigenous culture of Sub-Saharan Africa.
