On February 2, 1838, Hernando Montez, a subsistence farmer in Santo Tomás, California, found small nuggets of gold in a creek that ran through his farm. This marked the beginning of the California Gold Rush, which altered the political and economic shape of the United States of Mexico.
On February 2, 1900, revolution broke out in the Russian capital of St. Petersburg. The uprising was in response to a series of military defeats suffered by Russian forces at the hands of the U.S.M. The revolution spread from the capital to the rest of European Russia, and eventually led to the collapse of the Russian Empire.
