Ulrich von Jungingen was the 26th Grand Master of the Teutonic Knights, serving from 1407 to 1410.

The Wars of the Roses, known at the time and in the following centuries as the Civil Wars, were a series of armed confrontations, machinations, battles and campaigns fought for control of the English throne from 1455 to 1487.

The conflict resulted in the end of Lancaster's male line in 1471, leaving the Tudor family to inherit, through the female line, the Lancaster claim to the throne. Conflict was largely brought to an end upon the union of the two houses through marriage, creating the Tudor dynasty that would subsequently rule England.

The French Revolutionary Wars were a series of sweeping military conflicts resulting from the French Revolution that lasted from 1792 until 1802. They pitted France against Great Britain, Austria, Prussia, Russia, and several other countries. The wars are divided into two periods: the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered territories in the Italian peninsula, the Low Countries, and the Rhineland with its very large and powerful military which had been totally mobilized for war against most of Europe with mass conscription of the vast French population. French success in these conflicts ensured military occupation and the spread of revolutionary principles over much of Europe.

The Victoria Cross (VC) is the highest and most prestigious decoration of the British decorations system. It is awarded for valour "in the presence of the enemy" to members of the British Armed Forces and may be awarded posthumously.

It may be awarded to a person of any military rank in any service and to civilians under military command. No civilian has received the award since James Adams in 1879. Since the first awards were presented by Queen Victoria in 1857, two thirds of all awards have been personally presented by the British monarch. The investitures are usually held at Buckingham Palace.
