American frontierThe American frontier, also known as the Old West, popularly known as the Wild West, encompasses the geography, history, folklore, and culture associated with the forward wave of American expansion in mainland North America that began with European colonial settlements in the early 17th century and ended with the admission of the last few contiguous western territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist attitude known as "Manifest Destiny" and the historians' "Frontier Thesis".

HolodomorThe Holodomor, also known as the Great Ukrainian Famine, was a man-made famine in Soviet Ukraine from 1932 to 1933 that killed millions of Ukrainians. The Holodomor was part of the wider Soviet famine of 1930–1933 which affected the major grain-producing areas of the Soviet Union.

Some historians conclude that the famine was planned and exacerbated by Joseph Stalin in order to eliminate a Ukrainian independence movement.
