Problem: Background: The Blackfoot Confederacy, Niitsitapi or Siksikaitsitapi (nitmowmeko, meaning "the people" or "Blackfoot-speaking real people") is a historic collective name for the four bands that make up the Blackfoot or Blackfeet people: three First Nation band governments in the provinces of Saskatchewan, Alberta, and British Columbia, and one federally recognized Native American tribe in Montana, United States. The Siksika ("Blackfoot"), the Kainai or Kainah ("Blood"), and the Northern Piegan or Peigan or Piikani ("Apa'tosee" or "Poor Robes") reside in Canada; the Southern Piegan/Piegan Blackfeet ("Amskapi Piikani" or Pikuni) are located in the United States, where they are also known as the Blackfeet Nation. In modern use, the term is sometimes used only for the three First Nations in Canada. Historically, the member peoples of the Confederacy were nomadic bison hunters and trout fishermen, who ranged across large areas of the northern Great Plains of western North America, specifically the semi-arid shortgrass prairie ecological region.
Context: The Niitsitapi, also known as the Blackfoot or Blackfeet Indians, reside in the Great Plains of Montana and the Canadian provinces of Alberta and Saskatchewan. Only one of the Niitsitapi tribes are called Blackfoot or Siksika. The name is said to have come from the color of the peoples' moccasins, made of leather. They had typically dyed or painted the soles of their moccasins black. One legendary story claimed that the Siksika walked through ashes of prairie fires, which in turn colored the bottoms of their moccasins black.  Due to language and cultural patterns, anthropologists believe the Niitsitapi did not originate in the Great Plains of the Midwest North America, but migrated from the upper Northeastern part of the country. They coalesced as a group while living in the forests of what is now the Northeastern United States. They were mostly located around the modern-day border between Canada and the state of Maine. By 1200, the Niitsitapi were moving in search of more land. They moved west and settled for a while north of the Great Lakes in present-day Canada, but had to compete for resources with existing tribes. They left the Great Lakes area and kept moving west.  When they moved, they usually packed their belongings on an A-shaped sled called a travois. The travois was designed for transport over dry land. The Blackfoot had relied on dogs to pull the travois; they did not acquire horses until the 18th century. From the Great Lakes area, they continued to move west and eventually settled in the Great Plains.  The Plains had covered approximately 780,000 square miles (2,000,000 km2) with the Saskatchewan River to the north, the Rio Grande to the south, the Mississippi River to the east, and the Rocky Mountains to the west. Adopting the use of the horse, the Niitsitapi established themselves as one of the most powerful Indian tribes on the Plains in the late 18th century, earning themselves the name "The Lords of the Plains." Niitsitapi stories trace their residence and possession of their plains territory to "time immemorial."
Question: what other tribes were they associated with?
Answer: Only one of the Niitsitapi tribes are called Blackfoot or Siksika.

Context: On August 10, Jericho defeated Stevie Ray to win the World Television Championship (Stevie Ray substituting for the champion Booker T). Soon afterward, Jericho repeatedly called out WCW World Heavyweight Champion Goldberg in an attempt to begin a feud with him, but never actually wrestled him. Jericho cites Eric Bischoff, Goldberg and Hulk Hogan's refusal to book Jericho in a pay-per-view squash match loss against Goldberg, which Jericho felt would be a big draw, as a major reason for leaving the company.  On November 30, Jericho lost the World Television Championship to Konnan. In early 1999, Jericho began a feud with Perry Saturn. The feud saw Jericho and Saturn instigating bizarre stipulation matches, such as at Souled Out, where Jericho defeated Saturn in a "loser must wear a dress" match. At SuperBrawl IX, Jericho and Saturn wrestled in a "dress" match which Jericho won. Saturn finally defeated Jericho at Uncensored in a Dog Collar match. Jericho alternated between WCW and a number of Japanese tours before he signed a contract with the World Wrestling Federation (WWF) on June 30. Jericho's final WCW match came during a Peoria, Illinois house show July 21, where he and Eddie Guerrero lost to Billy Kidman and Rey Mysterio Jr. in a tag team match.  Fifteen years after Jericho's departure from WCW, his best known entrance music within the company, "One Crazed Anarchist", lent its name to the title of the second single from his band Fozzy's 2014 album, Do You Wanna Start a War.
Question: Did Jericho participate in any tag team matches in the 1998 to 1999 period?
Answer:
Illinois house show July 21, where he and Eddie Guerrero lost to Billy Kidman and Rey Mysterio Jr. in a tag team match.
