-1380 AD: The Red Death appears in <INSERT NATION>.
-1386 AD: Brugse Vrije is added to the Three Members, turning the organization into the
Four Members.
-1402 AD: The Red Death intensifies, becoming more deadly than the Black Death of 1348.
-1405 AD: The Red Death reaches Europe. Having barely recovered from the Black Death, widespread panic and chaos follows in the wake pf this new epidemic.
-1407 AD: Louis I, Duke of Orleans, is assassinated at the command of John the Fearless, Duke of Burgundy. Civil war erupts between Armagnac and Burgundy in France.
-1409 AD: The Red death reaches France. Already in the midst of a civil war, the country is further destabilized, and soon, peasant revolts and desertions become commonplace.
-1411 AD: Rebelling nobles succeed in killing John the Fearless on the field of battle. The nobles then proceed to sack the city of Dijon, resulting in the death of the majority of the House of Valois-Burgundy and the collapse of the Duchy of Burgundy. The last surviving heir, Philip III, is rumored to have subsequently fled to Switzerland.
-1412 AD: The Red Death finally recedes from Europe. However, in its wake, it has left kingdoms shattered, and bandits and lawless nobles ravage the land. During this time, the Four Members, spurred on by the merchant guilds, rebel against the Count of Flanders, driving him out and taking control of the county.
-1413 AD: With the collapse of trade, the power of the merchant guilds has rapidly declined. With no ability to maintain order, the Four Members can do little but watch as their hold on the County of Flanders grows weaker and weaker, until they are rulers in name only.
-1423 AD: Hugh III, the deposed Count of Vermandois, invades Flanders. The Four Members call upon the communes to send troops to rebel the lawless count, but few heed the call to arms.
-1424 AD: Hugh III defeats the Four Members at the Battle of Tournai, and brutally sacks the city. This finally prompts the communes to join together to repel the wayward noble.
-1426 AD: Hugh III is defeated and killed at the Battle of Waregem. His armies are scattered, and most of the forces are routed.
-1427 AD: In an effort to better defend themselves, the communes of Flanders agree to form the Union of Flanders, an organization dedicated to the defense of Flanders. The Four Members are made the head of the Union, but have their power limited.
-1444 AD: The city of Antwerpen petitions to join the Union of Flanders, in order to protect itself from the newly formed Duchy of Brabant. When it is admitted in, the Duke of Barbant, Philip II, declares war on the Union, and lays siege to the city.
-1445 AD: A relief force led by Jacob van Brugge is defeated by Philip II's armies. The city of Antwerpen falls soon after, and Philip II crosses the Schelt into Flanders.
-1446 AD: Philip II lays siege to Ghent, while sending his general, Louis van Breda, southwest to take Ypres. However, he is defeated and routed at Kortrijk by Johan van Ypres. around the same time, a major revolt in Brussels forces Philip II to break the siege of Ghent in order to crush it.
-1447 AD: Michiel Huygens lays siege to the city of Antwerpen, which falls after only a month. He then moves south, where he confronts and defeats Philip II's army outside of Mecheln. Philip II is mortally wounded, and dies a short while after. Without a proper heir, the Duchy of Brabant dissolves, as nobles attempt to seize control.
-1448 AD: Huygens captures the city of Brussels, signing a peace treaty with the only noble who continued the war, Louis II. The treaty stipulates that the cities in southern Brabant be allowed to decide their own fate, free from interference from nobility. Subsequently, many cities petition to join the Union, and are accepted. However, in an effort to avoid further conflict, the Grand Council declares that any new admissions to the Union be approved by a majority vote in the council.
-1449 AD to 1500 AD: Nothing too important that I want to write about in detail. Antwerpen is added to the Four Members, changing it to the Five Members; the wool and cloth industries make a comeback, bringing wealth back to Flanders; and some more people get stabbed.
