Predecessor clubs (1905–1945)

Trier FC was established 11 March 1905 and in 1911 was renamed Sport-Verein 05 Trier. In 1930, 05, Fußballverein Kürenz, and Polizei SV Trier were joined to form SV Westmark 05 Trier.

The origins of Eintracht Trier are in the 1906 establishment of Fußball Club Moselland 06 Trier. In 1920, the club joined with FV Fortuna 1910 Trier to create Vereinigte Rasenspieler 1906 Trier, which the following year merged with SV Alemannia 1909 Trier to form SV Eintracht 06 Trier.

Westmark and Eintracht played first in the Bezirksliga Rhein-Saar and then in the Gauliga Mittelrhein, one of 16 top-flight divisions formed through the 1933 re-organization of German football under the Third Reich. Westmark appeared in the opening rounds of the Tschammerpokal, predecessor of today's DFB-Pokal (German Cup) in 1936, advancing past FV Saarbrücken (3–1), before being put out in the next round by VfB Stuttgart (0–1). Both Trier teams were relegated in 1936 and did not re-appear in the top-flight until 1941 when they were both promoted to the Gauliga Moselland, Gruppe West.

Westmark was relegated at the end of the season, however Eintracht fared slightly better, lasting a further two seasons before being sent down. Player shortage during World War II forced the mergers of many clubs into combined wartime clubs known as Kriegspielgemeinshaft, and in 1943, the two clubs were joined as KSG Eintracht/Westmark Trier. The team won only a single point in 11 matches, conceding 52 goals and scoring just 13. By 1944, the region was strongly affected by the war and matches of the Gauliga Moselland were eventually suspended.

Post-war (1945–2000)

The two clubs re-emerged as separate sides after the conflict but joined to one club on 11 March 1948 as SV Eintracht Trier 05. The newly combined side resumed playing in the top-flight Oberliga Südwest (Gruppe Nord), but were never a serious contender at that level, consistently finishing well behind the leaders. By the time the Bundesliga, the new nationwide professional football league, was formed in 1963, the club played in the second division.

They continued to play tier II football in the Regionalliga Südwest until slipping to the Amateurliga Rheinland (III) in 1973. Eintracht's second team amateur side had also made an appearance in the Amateurliga for a single season in 1970–71. The senior side performed well in the Amateurliga after their descent, but failed in a bid to advance at the end of the 1975–76 season after winning their division and then finishing second in the relegation play-off group. The following year, Trier again captured the Amateurliga title, but this time were successful in their bid to move up to the 2. Bundesliga Süd. However, they performed poorly there and were in 17th place at the end of the 1976–77 campaign. The club avoided relegation only because Röchling Völklingen, who had finished above Eintracht, were denied a license for financial reasons. Trier was able to turn their narrow escape into a five-year stay in the second division.

In 1981, the Nord and Süd divisions of the 2. Bundesliga were combined, and the number of teams playing tier II football reduced from 42 to 20. Trier missed the cut with an 8th-place finish and found themselves playing in the Amateuroberliga Südwest (III). The club went on to perform well through the next decade and on into the mid-1990s, earning a string of top three finishes which included Amateurliga titles in 1986, 1993, and 1994 and consecutive German Amateur Championships in 1988 and 1989. They also enjoyed an extended run in the 1998 DFB-Pokal (German Cup) tournament, advancing to the semi-finals before finally being put out by MSV Duisburg in a match that ended in a 1–1 draw before being decided 9–10 on penalty kicks. However, the team failed in four opportunities (1987, 1992, 1993, 1999) to win its way back to second division play and remained a mid-table side in the Regionalliga West/Südwest and Regionalliga West for most of the 1990s and on into the new millennium.

Recent history

From 2002 to 2005, the club enjoyed a three-season spell in the 2. Bundesliga, earning their highest finish with a 7th-place result in 2003.

The decline of the club began with relegation to the Regionalliga (III) in 2005. Club manager Paul Linz resigned and was replaced by former Trier Captain Micheal Prus. The start of the Regionalliga season was disappointing and led to replacement of the former manager with Eugen Hach in October 2005, which however failed to stop the decline. The team was again relegated and started the 2006–07 season in the Oberliga Südwest (IV).

The aim of the club was promotion straight back to the Regionalliga and the men in charge of this challenge were Adnan Kevric and Roland Seitz. However, Seitz left to take over at SC Paderborn within just a few days of his appointment. Kevric was to see out the rest of the season with the team before resigning his position on 3 March 2007 after a 2–0 home defeat at the hands of FV Engers 07 which finally ended all hopes for promotion. Herbert Herres then took over as head coach, but he in turn resigned as manager on 3 April 2007 following a 3–1 defeat against SpVgg EGC Wirges. Former player Werner Kartz took over until the end of the season.

Under Kartz the team was able to lift itself once again and even managed to win the Rhineland Cup after a 2–1 victory over TuS on 7 June 2007, leading to qualification to the opening round of the DFB-Pokal. On 5 August 2007, Trier met FC Schalke 04 at the sold out Moselstadion with tickets for this event changing hands on eBay for over 60 euros per ticket. Trier did not stand a chance and was beaten 9:0 by the Bundesliga side.

The plan for the 2007–08 season was to finish in the top four of the Oberliga Südwest (IV) to ensure promotion into the newly formed Regionalliga West (IV) for the 2008–09 season. The team met this objective in a 5–0 win over Eintracht Bad Kreuznach that locked their place in the top four. It played in this league until 2012 when it became part of the new Regionalliga Südwest.
