BSK Olympia Neugablonz

Coat of arms of Gablonz.

The club was formed on 21 October 1950 under the name of BSK Neugablonz and took up play in the local C-Klasse the lowest possible level, in 1951.[2] Formed by refugees from the city of Gablonz, it saw its roots in the ethnic German sport clubs of that city.[2] The club's current crest still bears a lot of similarity with the coat of arms of modern-day Jablonec nad Nisou, specifically the apple tree. A club under the name of BSK Gablonz had last played in the Gauliga Sudetenland in 1938–39. The crest of this old BSK Gablonz is almost identical to the crest of the new club.[5] In 1939, BSK merged with two other local sides to form NSTG Gablonz, a club controlled by the Nazis, NTSG standing for Nationalsozialistische Turngemeinde.

The new BSK quickly rose through the ranks of local football, rising through the B-Klasse to the A-Klasse. The clubs first great success came in 1964, when it won its first Schwaben Cup, beating TSV Gersthofen 5–2. The year after, it won the Bezirksliga Schwaben and earned promotion to the tier-four Landesliga Bayern-Süd. It also made another appearance in the Schwaben Cup final, losing to BC Augsburg.

In the Landesliga, the team finished eighth in 1965–66,[6] followed by a sixth place the season after. It took out the Cup once more in 1966.

The 1967–68 season saw the team compete against newly promoted local rival SpVgg Kaufbeuren in the Landesliga. SpVgg won the league and earned promotion to the Bayernliga while BSK finished fourth.[7] After a fifth place in 1969, the team had a terrible 1969–70 season, finishing second-last with an eight-point gap to a non-relegation rank, and had to return to the Bezirksliga.[8]

In the Bezirksliga, now divided into a northern and a southern group, with BSK playing in the later, the club started under a new name, BSK Olympia Neugablonz, after a merger with local side TSV Olympia Kaufbeuren.[2] It spent four seasons at this level, earning another cup win in 1973 and winning the league in 1974.

Upon return to the Landesliga, the team established itself as an upper-table side, finishing seventh and fourth in its first two seasons there. In 1976–77, rival SpVgg Kaufbeuren returned to the league from the Bayernliga and BSK Olympia managed only an eleventh place, troubled by relegation worries.[9] The season after, the club improved by a place but finished ahead of SpVgg. The 1978–79 season became the club's best ever. Winning the Schwaben Cup for a fourth time, defeating SV Salamander Türkheim in the final, and qualifying for the first round of the German Cup by doing so, it came third in the Landesliga, only two points short of the two teams ahead of it.[10] It played Eintracht Frankfurt in the first round of the German Cup in August 1979, losing 6–1.

The team slipped to eighth place in the following season and finished last in the league in 1981, making a permanent departure from the Landesliga.[11] The club had to sell its stadium to the city of Kaufbeuren for financial reasons in the 1980s.[12]

BSK Olympia declined from then on, at first playing in the Bezirksliga Schwaben-Süd again, then dropping to the A-Klasse Schwaben-Süd and finally, in 1994, to the B-Klasse Ostallgäu. It moved between the B-Klasse and the A-Klasse in the following years, the later being renamed Kreisliga Schwaben-Süd in 1998, The club finished runners-up in this league in 2002, the best result in over a decade.

In 2006, the club finally won the Kreisliga and made a return to the Bezirksliga, where it finished a respectable fifth in its first year back.[13] It however suffered another relegation in the following season, back to the Kreisliga, which had become the ninth tier of the German football league system because of the introduction of the 3. Liga.

In 2009, the club returned to the Bezirksliga on the strength of a title in the Kreisliga Schwaben-Mitte (IX).[14]

In 2009, a friendly was planned between the BSK and FK Baumit Jablonec in an attempt to improve contacts between Neugablonz and Jablonec nad Nisou.[15]
