Answer:
Gavrilo Princip
Explanation:
Princip was the Serbian who assassinated Archduke Franz Ferdinand, which sparked World War I. Following World War I, Russia weakened as it cannot take on providing a second front for the Allies as well as fighting a civil war. Russia lost against the communist forces, which led to the Communist rise to power, effectively eliminating Russia from World War I. Enter in the U.S.S.R, which then made dealings with Germany, in which they were able to take satellite countries for themselves in Europe. They then joined the Allied side & helped defeat the Axis, which in turn granted them territories, which helped expand their sphere of influence. As the Market Economy & Command Economy are on the opposite spectrum, and with the arms build up, the world entered into the Cold War.
Without Princip assassinating Archduke Franz Ferdinand and his wife, none of this may have happened.
