U.S. Constitution ratified, establishing the world’s oldest written national charter

The U.S. Constitution crossed its ratification threshold on June 21, 1788, when New Hampshire became the ninth state to approve it, meeting the bar set in Article VII. It replaced a crumbling framework under which the federal government couldn’t reliably collect taxes or pay its soldiers. More than two centuries later, it remains the oldest written national constitution still in force.

U.S. Constitutional Convention reframes how a nation can govern itself

The U.S. Constitutional Convention opened in Philadelphia in May 1787, where 55 delegates arrived expecting to patch up the Articles of Confederation and ended up drafting something entirely new. Over a sweltering summer, they hammered out compromises on representation, slavery, and executive power. The result, ratified the following year, remains the world’s oldest written national constitution still in use.

Dorset culture emerges across the Canadian Arctic

Dorset culture took shape around 500 B.C.E. across the Canadian Arctic, enduring nearly 2,000 years without bows, dogs, or many tools their neighbors relied on.

Poverty Point culture, flourishing along the lower Mississippi around 1500 B.C.E., built six concentric earthen ridges, a 50-foot pyramid, and a bird effigy mound near present-day Epps, Louisiana. Its people traded for copper and stone from sources up to 620 miles away, quietly proving that complex society took root in North America far earlier than once assumed.

Five nations found the Haudenosaunee Confederacy, a great league of peace

The Haudenosaunee Confederacy united five northeastern nations—Mohawk, Oneida, Onondaga, Cayuga, and Seneca—under a shared constitution sometime before European contact, with scholars placing its founding anywhere from 1142 to 1660 C.E. Guided by Deganawidah, Hiawatha, and Jigonsaseh, a Grand Council of 50 sachems governed by consensus, building one of the most sophisticated political systems in the pre-contact Americas.
