Lithuania actually has two key “independence” dates, both of which are important depending on what you mean by “gain independence.”

Short answer

  • First modern independence: 16 February 1918 – Act of Independence of Lithuania, declaring an independent Lithuanian state after World War I.
  • Restoration from the USSR: 11 March 1990 – Act on the Re‑establishment of the Independent State of Lithuania, restoring statehood after Soviet rule.

If someone asks “when did Lithuania gain independence,” they may be referring to either 1918 (from Russian/German domination) or 1990 (from the Soviet Union), so both dates are historically correct in context.

Quick Scoop on Lithuania’s Independence

1. The 1918 independence (often called “Independence Day”)

  • On 16 February 1918 , the Council of Lithuania signed the Act of Independence of Lithuania , proclaiming the restoration of an independent Lithuanian state based on democratic principles, with Vilnius as its capital.
  • This act is seen as the birth of modern Lithuania and is celebrated annually as Independence Day on 16 February.

You can think of 1918 as Lithuania stepping back onto the map as a sovereign state after centuries of domination and partitions.

2. The 1990 restoration (end of Soviet rule)

  • After World War II, Lithuania was occupied and incorporated into the Soviet Union , losing its de facto independence.
  • On 11 March 1990 , the Supreme Council of the Republic of Lithuania adopted the Act on the Re‑establishment of the Independent State of Lithuania , declaring that Lithuania was again an independent state and restoring the sovereign powers interrupted in 1940.
  • This made Lithuania the first Soviet republic to formally break away, triggering a wave of independence movements across the USSR.

Today, 11 March is celebrated as the Day of Restoration of Independence of Lithuania.

Why people online argue about the “real” date

In forum discussions and social media threads, you’ll often see comments clarifying that:

  • 16 February 1918 = original independence (Independence Day).
  • 11 March 1990 = restoration of independence from Soviet occupation (Restoration Day).

People from Lithuania and the Baltic region sometimes stress the word “restoration” to emphasize that their statehood existed before Soviet rule and that they were occupied , not “newly created” after 1990.

A typical clarification you’ll see in forum debates:
“March 11 is Restoration Day, not Independence Day; the actual Independence Day is 16 February 1918.”

This distinction has become part of how Lithuanians talk about their history and identity, especially in contrast to being labeled merely “former Soviet” states.

Timeline snapshot (for quick context)

  • 16 February 1918 – Act of Independence of Lithuania, modern Lithuanian state proclaimed.
  • 1940 – Soviet occupation and annexation into the USSR, ending de facto independence.
  • 11 March 1990 – Act on the Re‑establishment of the Independent State of Lithuania; independence from the Soviet Union is restored.

So, if you need a one‑liner for general use:

Lithuania gained independence on 16 February 1918 , and restored its independence from the Soviet Union on 11 March 1990.

TL;DR:

  • “When did Lithuania gain independence?” → 16 February 1918.
  • “When did Lithuania break away from the USSR?” → 11 March 1990.
