1939 German ultimatum to Lithuania

The Lithuanians had been expecting the demand after years of rising tension between Lithuania and Germany, increasing pro-Nazi propaganda in the region, and continued German expansion.

The United Kingdom and France followed a policy of appeasement, while Italy and Japan openly supported Germany, and Lithuania accepted the ultimatum on 23 March 1939.

It proved to be the last territorial acquisition for Germany before World War II, producing a major downturn in Lithuania's economy and escalating pre-war tensions for Europe as a whole.

[4] In January 1928, after long and difficult negotiations, Germany and Lithuania signed a border treaty, which left Klaipėda on the Lithuanian side.

In the wake of the amnesties, Lithuanian prestige suffered both abroad and in Klaipėda, allowing Germany to strengthen its influence in the region.

A week after Lithuania accepted the Polish ultimatum,[9] Germany presented an eleven-point memorandum that demanded freedom of action for pro-German activists in the region and a lessening of Lithuanian influence there.

[7] This tactic did not prove successful: pro-Nazi propaganda and protests were rampant, even among the Lithuanian population, and the local government was powerless to prevent them.

[10] Dr. Ernst Neumann, the chief defendant in the 1934 trials, was released from prison in February 1938 and became the leader of Klaipėda's pro-German movement.

[11] Neumann and other Nazi activists claimed the right of self-determination for the region and demanded that Lithuania open negotiations over the political status of Klaipėda.

Germany hoped that Lithuania would voluntarily give up the troubled region,[9] and a public stance could have disturbed the sensitive discussions it was then engaged in with Poland over an anti-Communist alliance against the Soviet Union.

On 12 March Foreign Minister Urbšys represented Lithuania at the coronation of Pope Pius XII in Rome.

[15] Italy and Japan supported Germany in the matter, while the United Kingdom and France expressed sympathy for Lithuania but chose not to offer any material assistance.

[16] The Soviet Union, while supporting Lithuania in principle, did not wish to disrupt its relations with Germany at that point, since it was contemplating a pact with the Nazis.

Article III: In order to make allowance for her economic needs, a Lithuanian free-port zone will be established for Lithuania in Klaipėda.

Adolf Hitler, arriving on board the cruiser Deutschland, personally toured the city and gave a short speech.

[18] President Antanas Smetona's unconditional acceptance of a second ultimatum in the space of a little over one year became a major source of dissatisfaction with his authoritarian rule.

However, even the looming international crisis did not induce Lithuanian politicians to unite, and they continued to engage in petty political disputes.

[9] The Nazis went so far as to suggest a German–Lithuanian military alliance against Poland and promised to return the Vilnius Region, but Lithuania held to its policy of strict neutrality.
