A lot of things did, in various places around the world. The events that jump out in my mind when those dates are mentioned are these:
<u>May 14th, 1948:</u>
The provisional government of the portion of the British Mandate for Palestine that was designated by the UN partition as reserved for Jewish administration declared that it was becoming a free and independent sovereign nation called Israel.
<u>May 15th, 1948:</u>
The massed armies of Syria, Egypt, Jordan, and Iraq rolled into Israel with big signs on the front of their tanks that read "Oh No You're Not !" .
Manifest Destiny was basically the idea of expanding the United States westwards. The term was coined in 1845 by a newspaper editor named John Louis O'Sullivan.
