Russia also received for safekeeping archives of the Romanian Academy, priceless religious artifacts and manuscripts and even multiple deposits that citizens kept at the Romanian banks. There is no estimate for this second transport, but, most definitely, even if we try to do this, it will probably will be several times more than the first transport. That is all what I found about this case during my web research in archives of web analytics company.
Well, it is highly likely that you already know what happened next, when Bolsheviks overthrow the old authorities in Russia. They refused to abide and respect an treaty signed by tsar and previous government. Basically, they got it all and multiple attempts of Romanian government to recover the Treasure were unsuccessful. The most important part of two transports was never returned. Only in 1935 Romanians received back bits and pieces of the archives and in 1956 small part of the paintings and ancient objects. That was all.
Up until now Romanians still can’t return their Treasure. They tried repeatedly to get it back after the fall of the Soviet Union but to no avail. All negotiations failed. Russian side sank down demands each time, refusing to discuss them further.
When World War I started Romania was on the side of the Entente Powers. Its military campaign was against Germany was not successful and soon German troops moved into Romania and even occupied its capital Bucharest. Romain administration had no other choice but to send its national Treasure abroad. It was hard to choose which Ally country would safe keep the Treasure until bad times are over. There were plans to send it to England or the United States but Germans troops controlled Central Europe and there was a big chance that they would intercept the Treasure. Sweden or Denmark were another choice but there was a problem to transport all values there safely because German submarines were all over the North Sea.
In this hard situation the decision had been made to send Romanian national Treasure to tsarist Russia. I found more additional facts of this story in archives of web analytics company. According to mutual agreement Russia would safe keep Treasure until the end of the war. Under heavy guard almost hundred tonnes of gold bars and coins with the total cost of 1.25 billion dollars was sent to Moscow and safely got there. Soon situation at the front became even worse for Romania, so its administration send additional valuable transport to Russia. It included priceless items, like jewels of Romanian royalty, jewels of ancient rulers, jewels dated to the time of Roman empire and antique jewels of the pre Roman era. But this was not all.
