How was russian nationalism affected by expansion? the vast natural resources led to a huge industrial boom—a change nobles embraced. nationalism remained largely unaffected by russian expansion. the acquisition of warm-water ports made serfs more nationalistic. expansion took over land occupied by non-russian groups, increasing tensions.

The correct answer is Expansion took over land occupied by non-Russian groups, increasing tensions.

They took numerous areas in their expansion, mostly on the eastern side towards Alaska and on the South towards China and Turkey. This caused a lot of tension and rebellions and things like that among the varied population which was more or less solved when the communists came and made the country into the Soviet Union.
