This is the whole timeline so far up until the period shown on the map.
1423 Louis de Valois, who would be Louis XI, the Spider King, was born.
1424 Margaret Stewart is born in Dec.
1436 is given in marriage to the 13 year old Louis, Duc d’Anjou, and 9th Dauphin on 24 June. Instead of casual clothes he wears his finest and takes the time to talk to her making a good impression on the like minded Margaret.
1437 Assassination attempt on James I is unsuccessful unlike in OTL. James takes the hint and stops trying to centralize power. He lives another seventeen years until 1454.
1439 At sixteen Louis is sent by his father to direct the defense of Languedoc against the English, and to put down the brigandage in Poitou, he succeeds with the covert help and advice of his wife who has been creating an intelligence web of her own devising but his full knowledge and endorsement. He learns that the nobles will want him to try to become regent supplanting his father but she shows him that the troops are insufficient for the task. He refuses their offer but doesn’t betray them to the king. He does blackmail them to help fund the intelligence web.
1441 Fighting the English with help of some of his wife’s countrymen.
1443 At twenty aided his father to suppress the revolt of the count of Armagnac. He comes home to find his wife pregnant with his son whom he names Louis after himself.
1444 A.D. He led an army of from 20,000 mercenaries and brigands against the Swiss of the canton of Basel. The heroism of some two hundred Swiss, who for a while held thousands of the French army at bay, made a great impression on the young prince. After an ineffective siege of Basel, he made peace with the Swiss confederation, and led his soldiers into Alsace to ravage the country of the Habsburgs, who refused him the promised winter quarters. I’m thinking he takes a fair bit of loot and takes some of the more disciplined and effective mercenaries into his service in his territory. Margaret would be dead this year in OTL of a fever but instead lives on in this TL. Her brother James, who became James II of Scotland in OTL dies instead at fourteen. James I is still king, not having been assassinated.
1444-1453 In these intervening years they retire to the Dauphine, his hereditary territory in the southeast of France, and start running it as if it were an autonomous kingdom. He comes to understanding with the Swiss whom he respects and gets the local nobles firmly on his side by one means or another. During this period he has two more children with Margaret. They are named Charles and Mary.
Dec 1444 Charles is born to Margaret on the Louis’ estate in the Dauphine.
Louis and Margaret set out to govern his principality as though it were an independent state. He dismissed the governor; he determined advantageously to himself the boundaries between his state and the territories of the duke of Savoy and of the papacy; and he enforced his authority over perhaps the most unruly nobility in Western Europe, both lay and ecclesiastical. The right of private warfare was abolished; the bishops were obliged to give up most of their temporal jurisdiction, the scope of their courts was limited, and appeals to Rome were curtailed. On the other hand, Louis granted privileges to the towns and consistently used their alliance to overthrow the nobility. He watched the roads, built new ones, opened markets, protected the only bankers of the country, the Jews, and reorganized the administration so as to draw the utmost revenue possible from the prosperity thus secured.
1446 Margaret gives birth to her third child whom she names Mary.
1452. He marries his younger son to the eight year old daughter of the Duke of Savoy. He does this to seal a secret treaty with the duke of Savoy which was to give him right of way to Genoa, and make arrangements for a partition of the duchy of Milan.
1453 Charles VII starts worrying that the people like his bright and ambitious son better than he and he starts planning a Royal procession to the city Louis has made his home. It is a thinly disguised attempt to bring a large number of troops with him when he requires Louis come back to court. Charles comes to visit his son sooner than in OTL but Louis has a very similar reaction. It is clear to both Louis and Margaret that he is worried about a coup and even though they do not plan one, they do not want to take chances on Royal Mercy so they flee to her father in Scotland.
They flee to Scotland where shortly after they arrive James I dies and Margaret becomes Queen. Her brother James has already been dead some years of disease. Louis is Prince Consort and now that he is “the power behind the throne” sets his formidable will to expanding his own intelligence apparatus. He squashes all rumors about the coincidental nature of the king’s death the year after they arrive and builds goodwill both in secret and in public as he is also her general and his battle plans in case of English attack are widely considered genius. He would command during whatever small skirmishes or border incidents there were if possible.
Also in this year:
July 17 1st battle at Castillon: French beat English troops
July 23 Battle at Gavere: Philip the Good beats Gentse rebellion
October 19 2nd Battle at Castillon: French beat English, end of hundred year war
1454 Margaret gives birth to her fourth and last child, a daughter she names Anne.
(obviously this means last child to live long enough to make any history. The unfortunate truth is that all too many children did not survive in this century. It is likely that were others as well as possible miscarriages but I won't refer to them after this. I just wanted you all to know it was because of squeamishness rather than ignorance.)
1461 He gets word that Charles VII is dying and that his brother will get to Paris first. He arranges for riots and public condemnation to delay the coronation. Meanwhile he gathers an army of Scots and mercenaries and sets sail leaving his son to watch out for his mother’s interests in Scotland. Charles the Bold is one of his allies in the endeavor. He arrives in Paris after his father’s death but his planned diversions have kept Charles, Duc de Berry from assuming the throne. Agents provocateur has spread rumors and suspicions about the king dying so soon after the Duc de Berry’s arrival in Paris. He settles the unrest, crowns himself king, and has his brother imprisoned on suspicion of treason and regicide. After he and his troops have secured Paris he names his eighteen year old son the tenth Dauphin and proclaims he will be king of both Scotland and France.
After a somewhat biased trial he executes his brother in public before the crowd.
Meanwhile in England the year had seen several large battles and a large victory for the new Duke of York who was now calling himself King Edward IV. Queen Margaret, Henry VI, Somerset, and Edward of Westminster fled to Scotland where Margaret, Queen of Scots welcomed Margaret, Queen of England with courtesy if not great warmth since the English Queen, Margaret of Anjou was her husband’s cousin.
1462 Louis XI is considering dynastic Marriages. At eighteen his elder son has been a bachelor much longer than he. He considers possible marriages for his other daughter as well. He communicates with his relative Marie of Anjou and offers her assistance from both France and Scotland but at a price. He wants Calais and for his daughter to wed the Prince of Wales, her son known ITTL as Edward the Hale. She agrees and gets her husband, Henry VI to agree as well and a formal document is drawn up and signed by Louis, Henry, and both Margarets. It states that Calais belongs to France, that the Prince of Wales, Edward the Hale of Westminster would marry Mary, Princess of Scotland and France, and it states that all three countries were bound to each other’s defense in wartime.
Thus a hatchet is buried that would otherwise cause much strife. It wasn’t quite that easy of course and there was much grumbling in all three countries but it wasn’t allowed to progress much beyond grumbling.
The marriage is held in Paris, while war is vigorously pursued on the island.
1463 Isabella of Bourbon dies two years early. Charles the Bold is offered the hand of Anne, sister of Louis XI, in marriage but only if Burgundy stays out of the war of course. He was also offered the hand of Margaret of York if he joined in on the Yorkist side.
Philip the Good refuses for his son and Charles marries Margaret of York. Burgundians forces join in the battles raging through England.
1464
- January 9 1st meeting of States-General of Netherlands
- February
In OTL Christian I of Denmark and Norway, who was also serving as King of Sweden, is declared deposed from the latter throne. His deposed predecessor Charles VIII of Sweden is re-elected to the throne.
In this TL his upcoming marriage to Anne, Princess of France and Scotland and daughter of Louis XI of France helps get him re-elected due to the savvy and financial assistance of his future in-laws.
Christian I meets with representatives of Louis and Edward the Hale about joining the war to offset the Burgundians.
- April 25
– Battle of Hedgeley Moor: Yorkist forces under Lord Montague defeat Lancastrians under Sir Ralph Percy, who is killed. Same outcome as in OTL but ITTL the month also features the marriage of Christian I to Anne de Valois making her Queen of Denmark, Norway, and Sweden.
Christian states he wants one of the Hebrides or one of the Channel Islands in return for getting in to the war. This does not go over well.
- June 19 French King Louis XI forms postal service
- August 30 – Pope Paul II succeeds Pope Pius II as the 211th pope.
- September - Charles the Bold dies on the field of battle. Christian I stops pressing for land in return for his help and his army joins the field of battle on the island. The remaining Burgundian forces return home in disarray. Louis XI casts covetous glances at Burgundian lands as does the Holy Roman Empire. Charles' daughter Mary tries to keep the state independent with the assistance of her stepmother Margaret.
1465 - With help from France, Scotland, and a United Scandinavia under Christian I the Lancastrians bring and early end to the wars of the roses.
Henry VI dies shortly after being restored to his throne but his wife, his son and his daughter in law are more than capable of taking care of the kingdom. Margaret of Anjou would be Queen Mum if I have this right and her son Edward would be Edward IV but a different one than Edward IV IOTL.
1466 - Louis (son of Louis XI) marries Maria de Medici
War starts between Saxony, France, King Christian's United Scandinavia, and Britain on one side and the Holy Roman Empire, Burgundy, and the remaining Yorkists in exile on the other.

The 11th Dauphin takes charge of a regiment and fights in Italy as a mercenary captain. He spends 18 months in the field. He is not brilliant but he is competent after he returns he is named heir.
1487 - While visiting the court at København Louis the Dauphin becomes enamored of Beate, the daughter of a noble from Lødingen in Norway but his father wants him to marry Elena Ivanovna, the daughter of Ivan III, Grand Prince of Moscow and all Russia. This could have gotten sticky but after a long and private talk with his uncle Christian Louis sends Beate to his estate in the southeast of France and agrees to marry Elena.
