There was also a secret protocol on the pact, which was only revealed after The defeat of Germany in 1945, although there were leaks much earlier on its provisions to influence Lithuania.  According to the protocol, Romania, Poland, Lithuania, Latvia, Estonia and Finland were divided into German and Soviet “spheres of influence”.  To the north, Finland, Estonia and Latvia were classified in the Soviet sphere.  Poland should be divided in the event of “political reorganization”: the territories east of Pisa, Narev, Vistula and San Rivers would flow towards the Soviet Union and Germany would occupy the West.  Lithuania, bordering East Prussia, was attached to the German sphere of influence, but a second secret protocol, approved in September 1939, attributed most of Lithuania to the Soviet Union.  According to the protocol, Lithuania would retain its historic capital, Vilnius, controlled by Poland in the interwar period. Another clause provided that Germany would not interfere in the Soviet Union`s action vis-à-vis Bessarabia, which then belonged to Romania.  As a result, Bessarabia and the northern regions of Bucovine and Hertza were occupied by the Soviets and integrated into the Soviet Union. German-Soviet non-aggression pact, same Nazi-Soviet non-aggression pact, German-Soviet non-aggression treaty, Hitler-Stalin pact, Molotov-Ribbentrop Pact (August 23, 1939), Non-aggression pact between Germany and the Soviet Union, concluded a few days before the start of World War II, which divided Eastern Europe into German and Soviet influences. For decades, the official policy of the Soviet Union was to deny the existence of the secret protocol on the German-Soviet pact. On the orders of Mikhail Gorbachev, Alexander Nikolayevich Yakovlev headed a commission that investigated the existence of such a protocol.
In December 1989, the Commission concluded that the protocol existed and disclosed its results to the Congress of The People`s Deputies of the Soviet Union.  Congress then adopted the statement confirming and condemning and denouncing the existence of secret protocols.  The two successor states of the parties to the pact cancelled the secret protocols from the date of their signing: the Federal Republic of Germany on 1 September 1989 and the Soviet Union on 24 December 1989 after reviewing the micro-filmed copy of the German originals.  The secret services of the Baltic States did not express concern about the possible existence of a secret protocol until a few days after the signing of the pact. Speculation intensified when Soviet negotiators referred to their content during negotiations on military bases in these countries (see the occupation of the Baltic countries). After the conclusion of the trade and credit agreement between Germany and Germany, the question arises of the improvement of political relations between Germany and the USSR.  Despite the publication of the restored copy in the Western media, the official policy of the Soviet Union has for decades been to deny the existence of the secret protocol.  The existence of the secret protocol was officially denied until 1989.
