The '''major professional sports leagues in Latium''' are the highest professional competitions of team sports [[Latium]]. The four leagues traditionally included in the definition are [[Liga Campiontia]] (ICC), [[Insignis Liga]] (NIL), and [[Liga Magna]] (LMH). Other prominent leagues or competitions commonly included in this definition are the [[Liga 2 Calcitro]] (LC2), [[Canistriludium Liga]], and less often the [[Belisarian Gridiron League]] (BGL).

[[Liga Campiontia]], [[Insignis Liga]], and [[Liga Magna]] are commonly referred to as the "Big Three." They are among the wealthiest professional competitions in their respective sports worldwide, and are among the top ten sports leagues by revenue in the [[Ajax|world]]. Among the Big Three, only football, known in Latium as calcitro, had a history of rules that were developed in Latium, with hockey and lacrosse developing in [[Ghant]] and [[Ajax#Norumbia|Norumbia]] respectively. Due to the prominence of athletics in popular culture, many of the leagues star plays develop into cultural icons.

Each of the Big Three, and the BGL average a minimum of 14,000 in attendance per match. As Liga Magna is the only major league played indoors, most arenas are fitted for a minimum of 15,000 fans, with the largest at approximately 20,000. Many [[Liga Campiontia]] and [[Insignis Liga]] share venues, and achieve some of the highest attendance of fans due to the size of their respective stadiums.

With the exception of the BGL, these leagues range from 20 to 25 clubs. Both Liga Campiontia and Insignis Liga leagues field teams exclusively to Latium or its immediate territories, while Liga Magna includes teams from neighboring countries. All leagues, aside from the BGL, utilize some form of [[wikipedia:promotion and relegation|promotion and relegation]]. While rare, relocation can occur, but this often leads to the formation of a new club in a lower tier. When this occurs the relocated team is considered a new entity and a potential phoenix club may retain the original identity.

Professional [[wikipedia:Association football|Association football]] and [[wikipedia:lacrosse|lacrosse]] leagues have existed in Latium for over 100 years, in the form of [[Liga Campiontia]], [[Insignis Liga]] respectively. Hockey Campiontia, the predecessor to Liga Magna, was first formed in 1933, and folded during the [[Social War]]. Liga Magna is considered the legal successor to Hockey Campiontia, and played its first season in 1951.

Teams that finish the regular season in positions second through four qualify for the Champions League, with teams finishing in positions five to seven in the [[BFFA Leagues Cup]].

==Other notable professional leagues==
National sports journalists have made the argument for the inclusion of Liga 2 Calcitro, Canistriludium Liga, and [[Belisarian Gridiron League]] in the major professional sports leagues.
===Liga 2 Calcitro===
{{also|Liga 2 Calcitro}}
Liga 2 Calcitro, commonly referred to as Liga 2, is the second tier or the Latin football league system. The league features 22 clubs participating in a 42 game season. As the second level of the football system, it features the promotion of 3 clubs to Liga Campiontia through the league champion and a promotion playoff. Likewise, 3 clubs are relegated to Liga 3 Calcitro at the end of the season. It is rarely included in the major professional leagues due to its status as the second tier league in Latin football. Despite this status, it features a high level of competition, and commonly features an average attendance of at least 20,000. The league also plays well on television, with a strong presence due to its recent broadcast contracts and regional viewership.
===Canistriludium Liga===
{{also|Canistriludium Liga}}
[[Nationale Canistriludium Liga]] (NCL) is the top flight basketball league in Latium. It is the highest level of play in basketball within Latium.

Since 1970, the league has been operated by the Latin national basketball federation. Most of the oldest extant clubs are closely associated with sporting clubs that field teams in other sports such as football, lacross, or in less cases hockey. Since 2015, the NCL has consisted of 15 teams, and features promotion and relegation. Unlike other basketball leagues, the NCL's season runs from spring to fall in order to more easily fill arena space; however, the federation has recently explored moving the season to a more traditional fall to spring calendar.
===Belisarian Gridiron League===
{{also|Belisarian Gridiron League}}
The Belisarian Gridiron League is a international league of [[wikipedia:Gridiron football|gridiron football]] clubs throughout Belisaria. Despite holding a niche position in the Latin sporting world, the Belisarian Gridiron League is most often not included in the list of major professional leagues due to the multi-national basis of its league. Since 1999, three teams have been based in Latium: Gladiatores AHS<!--Alban Gridiron Society Gladiators-->, Adrianopolis SHS<!--Sabine Gridiron Society of Adrianople-->, and Lupi Ascanium<!--Ascanium Wolves-->. All three teams share venues with association football clubs in their cities. Due to the international nature of the league, it is the only top flight professional team sports league in Latium that is a closed league without promotion and relegation.

==Traits of the major leagues==
Liga Campiontia, Insignis Liga, and Liga Magna stand out among other sports leagues in Latium due to their business and economics, as well as the popularity, visibility both domestically and abroad, and the quality of play.

==Relations between the major leagues==
Relations between the major leagues themselves remains minimal, due to competition for viewership, participation, sponsorship money, etc. However, strong relationships exist among teams found in all three leagues due to the commonplace of [[wikipedia:Sports club|sporting societies]] in professional and amateur athletics in [[Latium]]. As of 2021, X sporting clubs field teams in at least two of the major leagues. An additional X number of teams in each league feature shared ownership, though are not among the same sporting society. The shared ownership feature most commonly includes clubs in Liga Magna. Many teams in Liga Campiontia and Insignis Liga share match venues and training facilities due to the staggered nature of each league's regular season; however, this causes scheduling conflicts near the ends of each league's respective end.
