Roughly two weeks after 104 English settlers came ashore on a marshy peninsula in the Chesapeake, colonists worked to erect a wooden palisade fort against the threat of attack from the powerful Powhatan Confederacy.

Days after Mexican forces under General Ignacio Zaragoza repelled a much larger, better-equipped French army at the Battle of Puebla on May 5, 1862, word of the victory solidified into a rallying cry for Mexican nationalism.

Hours after British Mandate authority formally lapsed and Israeli leaders proclaimed the new state's independence, five Arab nations sent troops across its borders, rejecting the United Nations partition plan.

Mid-1950s Soviet computing centered heavily on institutes in Minsk and Moscow, racing to close the technological gap with the West.
