Cardinal Nation, or Redbird Nation, is a term sometimes used to describe, in aggregate, the fans of the St. Louis Cardinals baseball franchise. The term takes after the popular phrase "Red Sox Nation" originally coined by Boston Globe feature writer Nathan Cobb in an October 20, 1986, article about split allegiances among fans in Connecticut during the 1986 World Series. Cardinal Nation encompasses not just the area around St. Louis, but also a large portion of the Midwest and South. The team is traditionally popular in these regions and Cardinals games are broadcast on radio and television affiliates in ten states: Oklahoma, southern and central Illinois, southwest Indiana, Iowa, western Kentucky, Missouri, Arkansas, west Tennessee and parts of northern Mississippi and Alabama.
In addition, the team is also popular in other major league markets, most notably in Colorado, where the Cardinals were the team of choice until the creation of the Rockies franchise in 1993. To this day, the Cardinals have many fans in attendance at games on the road in Denver, as well as every other major league venue.
Historical background 
Major League Baseball experienced a half-century of stability from 1902 through 1952, during which no franchises moved and none were established or closed. During this time, The St. Louis Cardinals were the westernmost and southernmost major league franchise, and so geographically closest to anyone living southwest of a line stretching approximately from Savannah, Georgia through midstate Illinois into the Dakotas, which area encompasses much the greater portion of the United States. (The Cardinals shared this distinction with the St. Louis Browns, but the Browns were generally less successful and less popular.)
Although some franchises were established at the outer periphery of this area beginning in the 1950s (The Braves in Milwaukee in 1953, teams in California beginning in 1958, the Twins in Minneapolis in 1961) it was not until the establishment of the Houston Colt .45s in 1962, and more importantly the shift of the Braves to Atlanta in 1966 and the creation of the Kansas City Royals in 1969 that significant inroads into this market began. (And the Browns left St. Louis after 1953, ending whatever competition they offered for this fan base.)
During this period (1902 to 1962 and to some extent later) when the Cardinals were the closest team to a vast geographical area, baseball became firmly established as America's national pastime and by far its premier professional sport, commercial radio broadcasting -- including broadcasting of baseball games -- had been widely adopted and commonplace, and broadcasting at night and on television began. Also during this period the population of the Cardinals' mediashed grew considerably, even compared to the rest of the United States (the mean center of United States population moved from Indiana to the approximate location of St. Louis during this time).
During the core of this period the Cardinals were generally successful on the field, winning two league titles in the 1920s, three in the 1930s, and four in the 1940s. And in the latter part of this period, the Cardinals' games were broadcast on the 50,000-watt clear-channel radio station KMOX, which has the power to reach the entire continental United States at night.
All these factors combined such that for most of the 20th century the Cardinals' listening audience, and consequently fan base, extended throughout the American south and deep into the plains and Rocky Mountain states, a state of affairs that, although diminished, has persisted into the 21st century to some degree.
In St. Louis 
St. Louis is generally considered one of the best baseball towns in the United States, with fans more numerous, knowledgeable, and committed than in most cities. The Cardinals have been one of the most successful baseball franchises in history with 18 National League pennants and a National League record 11 World Series Championships. They are second only to the New York Yankees (who have 27) in total World Series Championships.
Cardinals fans are known for traveling to see their team on the road as well and fill nearly half of Wrigley Field in Chicago when the Cubs and Cardinals carry on their classic rivalry each season. (The converse is true when Cubs fans go to Busch Stadium in St. Louis when the Cubs visit.) When the Kansas City Royals play the Cardinals in Kansas City every season during interleague play, the games often sell out, unlike most other poorly-attended Royals' games. In the stands, Cardinals fans outnumber Royals fans almost two to one.
Many fans around the nation grew up listening to two baseball broadcasters considered among the best in history, Jack Buck and Harry Caray, call Cardinals' games starting in the mid-1940s, into the 1950s and through the 1960s. Jack Buck (with Mike Shannon, starting 1972), remained the voice of the Cardinals through 2001. KMOX dropped Cardinals' broadcasts after 2005, but resumed in 2011.
Winter Warm Up 
Like many other teams, Cardinals fans have a gathering of their own before the start of the regular season. During the Third week of January, Cardinals fans gather together at the Hyatt Regency in Downtown St. Louis at a pre-season convention called "Winter Warm Up", which is run by Cardinals Care - the charity fundraising arm of the Cardinals' organization. The last day takes place on Martin Luther King Day. One of the highlights of the event is the opportunity for Cardinal fans to get autographs from many of their favorite Cardinal players - past and present. All proceeds from the event, including those derived from the sale of autograph tickets for certain players (though some of them sign for free), go directly to Cardinals Care.
