The Underground Railroad – established during the early to mid-1800s. The Underground Railroad was a network of secret routes and safe houses in the United States used by African-American slaves to escape into free states and Canada with the aid of abolitionists and allies who were sympathetic to their cause. The term is also applied to the abolitionists, both black and white, free and enslaved, who aided the fugitives. Various routes led to Mexico or overseas. However, the network now generally known as the Underground Railroad ran north to the free states and Canada, and reached its height between 1850 and 1860. One estimate suggests that by 1850, 100,000 slaves had escaped via the "Railroad".

World War II – 1939-1945. Often abbreviated to WWII or WW2, World War II was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from over 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 70 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

Round 6 ...

Okay, I know this topic started off with the Alaska Purchase, but this is different.

Alaska was officially proclaimed a state on January 3, 1959. On March 30, 1867, the United States purchased Alaska from the Russian Empire for 7.2 million U.S. dollars, or approximately two cents per acre ($4.74/km2). The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959.
