After her return from Czechoslovakia on 10 February 1946, Mērija Grīnberga had to submit several accounts of her journey to the authorities. After she was forced to leave her position as acting head of the Ethnography Department of the Historical Museum, she had to submit an explanation to the Ministry of State Control of the Latvian SSR as to why she did not hand over the collections of the department to her successor, according to the rules. Although Mērija Grīnberga was born in St Petersburg and her spoken Russian was good, her written Russian was a little clumsy, but the draft is written very expressively, and describes in detail the attitude of the museum administration towards the museum collections and her personally. The drafts of the accounts written by Mērija are also interesting because they show how she gradually adopted the ideological language of the Soviet regime.
