Soon, Ravdonikas and other young Marxist archaeologists rose to significant positions in the archaeological community of the Soviet Union, with notable Marxist archaeologists of this period including Yevgeni Krichevsky, A.P. Kruglow, G.P. Podgayetsky and P.N. Tret'yakov. According to later archaeologist Bruce Trigger, these young archaeologists "were enthusiastic, but not very experienced in Marxism or in archaeology."[8] In the 1930s, the term "Soviet archaeology" was adopted in the country to differentiate Marxist archaeology as understood by Soviet archaeologists from the "bourgeois archaeology" of other, non-Marxist nations. Allying it firmly with the academic discipline of history, this decade saw the publication of many more archaeological books in the Union, as well as the start of what would become the country's primary archaeological journal, Sovetskaya Arkheologiya, and the opening up of many more archaeological units in universities.[9]
