Coventric!


Below, clubs are listed which were never relegated from their national first division after first gaining admittance to it. The appearance of some "big" teams, especially in "small" countries, will not be surprising, but the list is really meant to honour small teams that "won't be moved"; of course, they tend to disappear from the list if one waits long enough: the once embodiment of Unabsteigbarkeit, VfL Bochum, is now securely in the camp of the Fahrstuhlmannschaften and even Coventry City suffered relegation, leaving us with DOS kan niets - zelfs niet degraderen - but they're now known as FC Utrecht. Because of this, for many countries additionally clubs are listed that remained at the top level for several decades, so that Bochum and Coventry feature below after all.

Ever present founder members (of a nationwide first level) are indicated by having the year in which the first league season started in bold.


The records below are up to date as of December 31, 2021. Other countries will be added. Additions and corrections are welcome.

Indonesia

Since 1951; no proper promotion or relegation until 1978; note that none of the clubs

1951: Persidja/Persija (Jakarta)
1951: PSM (Makassar)
2004: Persela (Lamongan)
2011: Persiram/PS.TNI/PS.TIRA/TIRA-Persikabo

Clubs with an uninterrupted series of 20 or more seasons in the top flight since 1951
(not including the four abandoned seasons 1997/98, 2015, 2016 and 2020; between 1951
and 1978 only appearances in the final national stage are considered):

NB: PSM withdrew from the qualifying stage for financial reasons in 1952 and played
      in the breakaway LPI 2010/11-2013, but they were never relegated; they can be
      considered the continuation of the M.V.B. which entered the final two editions
      (1949 and 1950) of the championship organised by V.U.V.S.I./I.S.N.I.S. in the
      colonial era, giving them an ongoing series of 44 seasons;
    Persibaya can be considered the continuation of the S.V.B. which entered all 32
      editions of the championships in the colonial era held between 1914 and 1950,
      thus giving them an uninterrupted sequence of 63 entries (1914-2002).

Ireland

 44  Drumcondra (1928-1972) [into Home Farm]
 44  Waterford (United) (1945-1989)

NB: for a long time, there was no institutionalised relegation.
    Bohemians played in the Irish League (now restricted to Northern Ireland) 
      before the associations split in 1920, and were relegated in 1911.
    Derry City played in the league of Northern Ireland every season from 1929
      until 1972 before being forced out in the 1972/73 season due to safety 
      issues; they entered the league of the Republic of Ireland in 1985 (at 
      the second level).  They were never relegated in either league until
      being demoted for financial reasons at the end of the 2009 season,
      together with Cork City who had not been relegated since first gaining
      access to the top level in 1984.
    Drumcondra amalgamated into Home Farm 1972; the resulting club (called
      Home Farm Drumcondra in 1972/73 before reverting to Home Farm 1973)
      played 15 more seasons at the top level until relegation in 1987, so
      combined the two clubs played 59 seasons without interruption in the

      championships since 1900 (although they were nominally relegated in

      in addition, they didn't finish the championship in 1908).

Serbia(-Montenegro)

Since 1991, after the Croatian and Slovenian clubs had left the Yugoslav league;
note that the clubs from Bosnia-Herzegovina and Macedonia still were part of the

NB: does not consider moves between divisions 1/A and 1/B during the seasons from
    1993/94 to 1995/96, as all 20 clubs starting those seasons in either of them
    theoretically could win the title and thus should be considered a top level
    club (all of Hajduk Kula, Zemun, Rad Beograd and Buducnost Podgorica
    suffered at least one such relegation in the relevant series listed above,
    while Crvena zvezda, Partizan and Vojvodina never left 1/A).

Uruguay

Since 1900.

1900: Peńarol 
1901: Nacional 
2016: Boston River

NB: only counting the professional league (since 1932), Nacional and Peńarol
      are both unrelegated founder members.
    Peńarol were expelled from the Uruguayan association (together with
      Central) on November 20, 1922, after playing matches against teams from 
      the Argentine 'Asociación Amateurs de Football' (a rival organisation to
      the 'Asociación Argentina de Football'); at that time, they had played 
      16 league matches.  In 1923 and 1924 they played in a league organised 
      by the 'Federación Uruguaya de Football' before the leagues were united 
      in 1926 (there was no league competition in 1925); they were therefore 
      active at the top level in every season since 1900.

      format; qualifying for this was based on regional competitions.  In 1932/33 
      a national league with promotion and relegation was introduced, but there 
      was no championship in 1933/34 and one decided by a knock-out tournament in 
      1935/36.

NB: the last Yugoslav league season was held in 1990/91;
    Hajduk Split and Dinamo Zagreb have never been relegated in Croatia since;
    Rad Beograd were relegated in Serbia-Montenegro in 2003;
    Crvena zvezda Beograd and Partizan Beograd have never been relegated in
      Serbia-Montenegro or Serbia since the split(s).
