Founder of Islam (c. 570–632)

Muhammad was an Arab religious, military and political leader, and the founder of Islam. At the age of 40, he claimed to receive divine revelation from the archangel Gabriel, which formed the basis of the Quran. He sought to unite the Arab tribes under Islam, and led a series of battles that led to the creation of the first Islamic state with him as its head.

Imperial Vietnamese dynasty (1225–1400)

The Trần dynasty was a Vietnamese dynasty that ruled Đại Việt from 1225 to 1400. The dynasty was founded when emperor Trần Thái Tông ascended to the throne after his uncle Trần Thủ Độ orchestrated the overthrow of the Lý dynasty. The Trần dynasty defeated three Mongol invasions, most notably during the decisive Battle of Bạch Đằng River in 1288.

1568 treaty which ended the second war of the French Wars of Religion

The Peace of Longjumeau was signed on 23 March 1568 by Charles IX of France and Catherine de' Medici. The edict brought to an end the brief second war of the French Wars of Religion with terms that largely confirmed those of the prior edict of Amboise. Unlike the previous edict, it would not be sent to the Parlements to examine prior to its publication, due to what the crown had felt was obstructionism the last time.

1775–1783 conflict in North America

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the armed conflict that comprised the final eight years of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war's outcome seemed uncertain for most of the war, but Washington and the Continental Army's decisive victory in the Siege of Yorktown in 1781 led King George III and the Kingdom of Great Britain to negotiate an end to the war.
