1410-1429 Venice at war with the Muslim Turks

This twenty year period covers the reign of Henry IV who died in 1413 and was succeeded by his son Henry V who died of dysentery in 1422 and was succeeded by his infant son Henry VI.

In this period there was constant warfare in the world, the most terrible war being the 1416 war between Venice and the Turks.

Venice was a thriving and very wealthy city, doing trade with all parts of the known world, and a Turkish victory would have thrown Europe even further into the Dark Ages than it was already.

Henry V's reign began and ended with bloody wars in France to claim the kingdom of France which he considered to be rightfully his in that he was married to Catherine, the daughter of the French King Charles VI.

In 1415 the Battle of Agincourt, followed by a systematic conquest of Normandy in 1417, a civilian massacre at Caen and the surrender of Rouen in 1419. 

In 1420 he entered Paris under the Treaty of Troyes -- by which Henry was to rule France -- but the Dauphin rejected the treaty. Then Henry died, leaving the succession to his infant son Henry VI.

As well as Henry V's wars, the 1409-1410 Teutonic-Polish War was coming to an end and then came the 1416 war between Venice and the Turks, the 1420-1436 Hussite Wars and the 1425-1454 Wars in Lombardy.
