question: Rachel Parker Plummer was the cousin of a dominant figure in the Red River War who clashed repeatedly with what Colonel? 
answer: Ranald S. Mackenzie
context: Title: Roman conquest of Italy
  Passage: The Roman conquest of Italy was the result of a series of conflicts in which the city-state of Rome grew from being the dominant state in Latium to become the ruler of all of Italy.  The first major Roman conquest in historical times came with the final defeat of her neighbour Veii in 396 BC.  In the second half of the 4th century BC Rome clashed repeatedly with the Samnites, a powerful tribal coalition.  By the end of these wars Rome had become the most powerful state in Italy.  The last threat to Roman hegemony came when Tarentum enlisted the aid of Pyrrhus of Epirus during the Pyrrhic War (282 - 273 BC).  By 218 BC Roman conquest of Italy had been completed.  Conquered territories were incorporated into the growing Roman state in a number of ways: land confiscations, establishment of "coloniae", granting of full or partial Roman citizenship and military alliances with nominally independent states.  The successful conquest of Italy gave Rome access to a manpower pool unrivalled by any contemporary state and led the way to the eventual Roman domination of the entire Mediterranean world.
  Title: Internal conflict in Azawad
  Passage: The Internal conflict in Azawad has been a two-year-long insurgency in Northern Mali between a pro-independence ultra Nationalist group, the MNLA and a coalition of Islamists terror groups.  The conflict began when Northern Mali declared itself independent from the government creating the un-recognized state of Azawad.  Both the Islamists and MNLA formed an alliance in combatting the Malian government.  An internal conflict sprung up over the imposing of sharia law in the new state and the MNLA distancing itself from the coalition to a democratic state.  Islamists gained popularity amongst anti-Tuareg tribes that helped it overthrow MNLA authority in Gao.  Both sides clashed repeatedly leading to the Battle of Gao where the MNLA were driven from the North's two main cities, Gao and Timbuktu.  The MNLA soon lost all of its strongholds in the North in a matter of months.  They went into hiding secretly gaining support and strength.  The beginning of 2013 led the start of the French intervention in Mali that ousted the Islamists from the North's cities and brought back Malian authority.  The MNLA supported the French and Chadian forces in military operations against Islamists sanctuaries in the mountains.  The MNLA recaptured several important towns in the Kidal Region but refused to dis-arm or hand them over to the Malian government.  A series of Islamists sponsored terror attacks plagued MNLA forces for siding with the French.  Checkpoints and bases were targeted with suicide bombings that targeted MNLA members.  A peace deal was reached with the Malian army in June that let the army transverse freely in MNLA occupied zones that were under Malian jurisdiction.  Ethnic violence sprung over the murder of a Tuareg Government officers family.  The MNLA responded by harassing and murdering Fulani civilians who create a majority of Islamists rebels.  The Islamists stepped up their attacks in one such instance massacring 30 Tuareg merchants.  The MNLA has since been battling Islamists.
  Title: Red River Showdown
  Passage: The Red River Showdown, commonly called the Red River Rivalry, the Red River Classic, or the Red River Shootout, is an American college football rivalry game played annually at the Cotton Bowl stadium in Dallas, Texas, during the second weekend of the State Fair of Texas in October.  The participants are the Oklahoma Sooners football team of the University of Oklahoma and the Texas Longhorns football team of the University of Texas at Austin.  The game is played the week following the State Fair Classic featuring Prairie View A&M University and Grambling State University.  The series is one of the major rivalries in NCAA football and in all of American sports.  The name is derived from the Red River that forms part of the boundary between Texas and Oklahoma that has in the past caused conflict between the two states, most notably the 1931 Red River Bridge War.
  Title: Red River system
  Passage: The Red River system is a network of rivers surrounding the main river - Red River in North Vietnam.  These branches of the system contribute to or receive water from Red River.  Red River system, joining with the Thái Bình river system in the northeast, creates the Red River Delta - the second largest delta in Vietnam.  Because of the close relation between Red River system and Thái Bình river system, the two system are known as the common name "Red and Thai Binh rivers system".  Alluvium of the Red River system creates the central and south Red River Delta.  Two banks of the rivers are protected by a great dyke system.
  Title: Quanah Parker
  Passage: Quanah Parker (Comanche "kwana", "smell, odor") (  1845 or 1852 – February 23, 1911) was a Comanche war leader of the Quahadi ("Antelope") band of the Comanche people.  He was born into the Nokoni ("Wanderers") band, the son of Comanche chief Peta Nocona and Cynthia Ann Parker, an Anglo-American, who had been kidnapped as a child and assimilated into the tribe.  Following the apprehension of several Kiowa chiefs in 1871, Quanah emerged as a dominant figure in the Red River War, clashing repeatedly with Colonel Ranald S. Mackenzie.  With whites deliberately hunting American bison, the Comanche's primary livelihood, into extinction, Quanah finally surrendered and peaceably led the Quahadi to the reservation at Fort Sill, Oklahoma.
  Title: Red River Expedition (1806)
  Passage: The Red River Expedition, also known as the Freeman-Custis Expedition, Freeman Red River Expedition, Sparks Expedition, or officially as the Exploring Expedition of Red River in 1806, was one of the first civilian scientific expeditions to explore the Southwestern United States.  It was ordered to find the headwaters of the Red River (Red River of the South) from the Mississippi River as a possible trading route to Santa Fe, then under Spanish colonial control in New Mexico; to contact Native American peoples for trading purposes; to collect data on flora, fauna, and topography, and map the country and river; and to assess the land for settlement.  The Spanish officials intercepted the expedition 615 miles upriver, in what is now northeastern Texas, and turned it back before the party achieved all of its goals.
