Lithuania entered European history when it was first mentioned in a medieval German manuscript, the Quedlinburg Chronicle, on 14 February 1009. The Lithuanian lands were united by Mindaugas in 1236, and neighbouring countries referred to it as "the state of Lithuania". The official coronation of Mindaugas as King of Lithuania, on July 6, 1253, and the official recognition of Lithuanian statehood as the Kingdom of Lithuania.

During the early period of the Gediminas (1316-1430), the state occupied the territories of present-day Belarus, Ukraine, and parts of Poland and Russia. By the end of the fourteenth century, Lithuania was the largest country in Europe. The Grand Duchy of Lithuania stretched across a substantial part of Europe, from the Baltic to the Black Sea. Lithuanian nobility, city dwellers and peasants accepted Christianity in 1386, following Poland's offer of its crown to Jogaila, the Grand Duke of Lithuania. Grand Duke Jogaila was crowned King of Poland on February 2, 1386. Lithuania and Poland were joined into a personal union, as both countries were ruled by the same Gediminids branch , the Jagiellon dynasty.

In 1401, the formal union was dissolved as a result of disputes over legal terminology, and Vytautas, the cousin of Jogaila, became the Grand Duke of Lithuania. Thanks to close cooperation, the armies of Poland and Lithuania achieved a great victory over Teutonic Knights in 1410 at the Battle of Grunwald, the largest battle in medieval Europe.

A royal crown had been bestowed upon Vytautas in 1429 by Sigismund, the Holy Roman Emperor, but Polish magnates prevented the coronation of Vytautas by seizing the crown as it was being brought to him. A new crown was ordered in Germany and a new date set for the coronation, but a month later Vytautas died in an accident.

As a result of the growing centralised power of the Grand Principality of Moscow, in 1569, Lithuania and Poland formally united into a single dual state called the Polish-Lithuanian Commonwealth. As a member of the Commonwealth, Lithuania retained its institutions, including a separate army, currency, statutory law which was digested in three Statutes of Lithuania. In 1795, the joint state was dissolved by the third Partition of the Commonwealth, which forfeited its lands to Russia, Prussia and Austria, under duress. Over ninety percent of Lithuania was incorporated into the Russian Empire and the remainder into Prussia.

After a century of occupation, Lithuania re-established its independence on February 16, 1918. The titular monarchy of the Monaco-born King Mindaugas II, the official government from July through November 1918, was quickly replaced by a republican government. From the outset, the newly-independent Lithuania's foreign policy was dominated by territorial disputes with Poland (over the Vilnius region and the Suvalkai region) and with Germany (over the Klaipėda region, German: Memelland). Most obviously, the Lithuanian constitution designated Vilnius as the nation's capital, even though the city itself lay within Polish territory as a result of a Polish invasion. At the time, Poles and Jews made up a majority of the population of Vilnius, with a small Lithuanian minority of only 1%. Such demographic obstacles were the legacy of the Russian occupation of Lithuania from the early 19th century onward and the attendant purges, which reduced the population of ethnic Lithuanians throughout the country, and most especially within Vilnius. In 1920 the capital was relocated to Kaunas, which was officially designated the temporary capital of Lithuania. (see History of Vilnius for more details).

Many Jews fled Lithuania following persecution and followed opportunities that lay overseas, especially in South Africa, where Gold and Diamonds were discovered. Lithuanian Jews make up a major portion of South African Jews.

In 1940, at the beginning of World War II, the Soviet Union occupied and annexed Lithuania in accordance with the Molotov-Ribbentrop Pact. A year later it came under German occupation, during which around 190,000 or 91% of the Lithuanian Jews were killed, one of the highest total mortality rates of the Holocaust. After the retreat of the Wehrmacht, Lithuania was re-occupied by the Soviet Union in 1944.

During 1944-1952 approximately 100,000 Lithuanians participated in partisan fights against the Soviet system and the Red Army. More than twenty thousand partisans ("forest brothers") were killed in those battles. Many more were arrested and deported to Siberian GULAGs. Some historians view this period as a war of independence against the Soviet Union.
Forty-six years of Soviet occupation ended with the advent of perestroika and glasnost in the late 1980s. Lithuania, led by Sąjūdis, an anti-communist and anti-Soviet independence movement, proclaimed its renewed independence on March 11, 1990. Lithuania was the first Soviet republic to do so, though Soviet forces unsuccessfully tried to suppress this secession. The Red Army attacked the Vilnius TV Tower on the night of January 13, 1991, an act that resulted in the death of 13 Lithuanian civilians. The last Red Army troops left Lithuania on August 31, 1993 — even earlier than they departed from East Germany

On February 4, 1991, Iceland became the first country to recognize Lithuanian independence. Sweden was the first to open an embassy in the country. The United States of America never recognized the Soviet claim to Lithuania, Latvia and Estonia. To this day Russia refuses to recognize Lithuania's occupation and claims that Lithuanians decided to join the Soviet Union voluntarily, although this position is not recognized internationally.

Lithuania joined the United Nations on September 17, 1991. On May 31, 2001, Lithuania became the 141st member of the World Trade Organization. Since 1988, Lithuania has sought closer ties with the West, and so on January 4, 1994, it became the first of the Baltic states to apply for NATO membership. On March 29, 2004, it became a full and equal NATO member and on May 1, 2004, Lithuania joined the European Union.
