Foundation and Žalgiris dominance

The Lithuanian Basketball Association was founded on 22 April 1993, when eight of the strongest Lithuanian basketball clubs' officials met with representatives of the Šarūnas Marčiulionis basketball fund in Vilnius. The original eight teams were: Žalgiris Kaunas, Atletas Kaunas, Drobė Kaunas, Statyba Vilnius, Olimpas Plungė, BC Šilutė, Lietkabelis Panevėžys and Neptūnas Klaipėda. This association would soon be renamed to Lietuvos krepšinio lyga (LKL) due to legal issues, also announcing there that would start in the upcoming fall. By the end of spring, before the season started, the LKA and their new league accepted two more teams – Lavera Kaunas and NECA Kaunas.

Following the 1993–94 season, the finalists of last season's LKAL, Sakalai Vilnius & BC Šiauliai joined the league, while Drobė Kaunas decided to withdraw due to financial difficulties. The 1994–95 season saw the league's foreign players emerge as star power, before they were more known to be role players. In the 1995–96 season the league continued to accept the champions of the LKAL to the league, Savy Alytus joined the league. Sharpshooter Joe Vickery became the first foreigner to lead the LKL in scoring for Olimpas. League officials would start pressuring teams to play in better arenas by setting up certain criteria that were necessary to get accepted into the league. That's why no more teams were accepted until 1998 when Olimpas Plungė went bankrupt and was replaced by BC Kraitienė based in Marijampolė. Some of the strongest teams like Šilutė and Atletas faded away to the bottom of the league and left the league.

During this time period, the league had been dominated by Žalgiris. They won the league's championship trophy for six consecutive years, from 1994 through 1999. Their main rival during those years was Atletas Kaunas led by Saulius Štombergas and a young Žydrūnas Ilgauskas acquired from Žalgiris' youth team. Ilgauskas was selected 20th overall in the 1996 NBA draft, making him the first NBA player coming straight from the LKL. In 1999 Žalgiris, led by Tyus Edney, became the first Lithuanian team to win the top European basketball competition, the EuroLeague title.

Golden era of Lithuanian basketball

In the 1999–2000 season, Lietuvos rytas shocked defending EuroLeague champions Žalgiris by ending their dominant run. That sparked most likely the biggest rivalry in Lithuanian sports, the competitiveness has brought over to politics and society between the two biggest cities in Lithuania.

Modern era

2010–11 saw Žalgiris reclaim the title, beating Lietuvos rytas 4–1. In the finals of 2012 Žalgiris was the winner again, by sweeping Lietuvos Rytas 3–0. During the 2013–14 season, Žalgiris defeated Neptūnas in the final.^[]

The 2014–2015 season saw the introduction of the 'four wheel system', where all the teams have to play 40 games with no exceptions for teams competing in international competition like in the past. This year Žalgiris was able to finished 1st, but not before a dramatic win against Lietuvos rytas in the last game of the season 82–81.

"...there's no better advertisement for Lithuanian basketball than this match. The season is long, forty games, but everything is settled not only in the last game of the season, but in the last seconds of that game."

— Gintaras Krapikas, head coach of Žalgiris

Žalgiris continued to dominate in the playoffs sweeping rivals Lietuvos rytas once again in the final. Despite a familiar ending, the season was marked by the growing competitiveness of the league, Neptūnas joined Žalgiris and Lietuvos rytas as a powerhouse and this edition saw a couple of upsets and close games from teams such as Pieno žvaigždės and Juventus Utena. Although a strong competitor Prienai had an underwhelming season. However, the final saw a two usual suspects once again - Žalgiris and Lietuvos Rytas. The Greens once again took the trophy back home by beating rivals 4–0. Team from Kaunas was led by all around sharpshooters in James Anderson and Artūras Milaknis who averaged 15.3 and 14.3 points a piece. The latter was named the MVP of the finals.

Lietkabelis, Vytautas and Nevėžis competed in the Baltic Basketball League. Dzūkija was the only LKL club not participating in any European or regional tournaments.

The 2016–17 LKL season off-season saw the rise of Lietkabelis, as tensions between FIBA and the EuroLeague resulted into them receiving a wild card as replacement in the EuroCup and greatly improving their roster which included signing the Lavrinovič twins (Darjuš and Kšyštof). A record of 8 Lithuanian teams competed in a European tournament that season, which added to the ever-improving competitiveness of the league. Consequently, the LKL achieved the average attendance record, with more than 2,000 spectators per game, during the regular season. Only Lietkabelis was able to fight defending champion Žalgiris, as Žalgiris easily defeated other top contenders Lietuvos rytas and Neptūnas. In the LKL semifinals, Lietkabelis beat Lietuvos rytas 3–1, to advance to the finals for the first time - they lost to Žalgiris 4–1. Rytas won the third place over Neptūnas.

"Does not matter the strength of the opponent, no matter, if Žalgiris Kaunas or Rytas Vilnius wins, the result does not mater, it is important, that the Lord is with us."

— Pope Francis, during his speech with youngsters at the Cathedral Square in Vilnius, surprised by mentioning two strongest teams of the Lithuanian league.
