This is an abridged version of the actual timeline. To see more, look at the specialized pages.
1000 - Leif Erikson set out on an expedition to find new lands. First he came to Helluland, or "flat-stone land". Then, he reached Markland, or "Wood Land". Finally, he came across the warmer island of Vinland (Newfoundland OTL) with his crew of 35.
1003-1005 - Leif's brother Thorvald captains an expedition to Vinland, and spends two years there.
1021 - Seeing that the Vinlanders were weak, Norway forced Vinland to become a colony of the kingdom or else they were willing to go to war. The Vinlanders agree, and 500 more people were ordered to come to Vinland to help with the colonization process.
1033 - The explorers in Slettene Land reach the southern point of OTL Nova Scotia, leading them to believe that it was an island. The explorers begin to make their way back up the land to the port built in Slettene Land.
1036 - After the original explorers return, 30 more settlers are sent down the coast of Vinland to create new settlements.
1042 - Due to the need for expansion, 25 horses were sent by barge to the port in Erstad. They are quickly bred and now have over 10,000 descendents on the continent.
May 1, 1053 - A violent pro-independent protest is held in Erstad, and the leader of the town violently murders the protesters. This becomes known as the May Day Massacre. Eighteen people died, including the leader of Erstad.
October 1054 - King Harald Sigurdsson's twisted advertising sends 1,200 people to Vinland by 1060. By October 1054 there have already been 150 people sent over. Vinland reaches five thousand people by 1057.
December 1054 - A ship sent by King Harald gets set off by a monsoon, leading them to what is now Värmland. This gives the people more information as to how big Erikson is. They make their way north and arrive in Langset.
Jul. 1056 - The Island of Vinland has been completely explored by this date.
1070 - In an attempt to build more towns and build up an army, the King of Vinland rapidly sends people up the coasts. This causes many conflicts with the natives, and makes them hostile for dozens of years to come.
1072 - The Governor of Helluland decides to send many missions to help fully explore the island. Lots of people ended up dying because of the cold Nord Helluland winter. The bottom half of Helluland is completely explored by 1089 and the top half is explored by 1113.
1078 - The population of Vinland reaches 15,000 people. The towns of Kysten Byen and Erstad are the two biggest towns in Erikson, with populations of over 2500. Places like Langset, Brosvik and Kalleburg all have over 750 people. Most other towns have populations of about 200-400. The province of Vinland has the most people, followed by Slettene Land, then Markland, then Helluland, then finally, Näätämö.
1082 - A pamphlet is written about Vinland, and is titled Historien om et nytt land (History of a New Land). It tells the story of how Leif Erikson discovered Vinland, and how it was taken over by Norway. Later in the book, it goes into detail about the daily life in Askim.
1089 - The bottom half of Helluland has been completely explored.
1092 - The town of Mesanga collapses after their third native war in thirty years.
1100 - The road network in Vinland is completed, and it already has 300 houses built on the path.
1101 - A rebel in Vinland, thinking that they could never become independent, reveals to Byzantine merchants the fact that there is another continent across the sea, and gives them a map.
1103 - Emperor Alexios I Komnenos of the Byzantine Empire sends Andrew Žekić on an expedition to Erikson. Instead of going north like he was sent, though, he gets blown off course and lands in OTL South Carolina. He sends Annved Helseth, one of his crewmen, back to Europe to give the Emperor the location of their settlement.
1113 - Helluland has been completely explored.
- 1438: After the complete separation from the Holy Roman Empire, the Dutch states of Holland, Utrecht, Gelre and Friesland erupt into the Dutch Civil War, a war for supremacy in the Dutch region.
- May: The Battle of Woerden takes place between Hollander and Utrechter forces, won convincingly by Holland and proving a major blow for Utrecht, as a large part of their army is wiped out.
- July: The Frieslander and Gelre army clash multiple times, but neither side make gains. Gelre goes on the defensive against Friesland, and sends a large army to Utrecht, planning to take the city before Holland does so
- August: Utrechter king Hugo I dies after being besieged, leading to Utrecht capitulating and opening the gates of the city of Utrecht. Both the forces of Gelre and Holland enter the city, and a battle erupts which destroys large parts of the city.
- April: The Battle of Utrecht takes a new twist, when Denmark-Sweden supports Holland with supplies. Modern historians suggest that it is very likely that Danish-Swedish troops were fighting alongside Holland. With the aid, Gelre is pushed out of the city.
- December: The December offensive starts, and Hollander forces with Danish-Swedish aid make a push towards Arnhem. Gelre desperately attempts to hold back both Friesland and Holland, but loses ground quickly
- 1443: The Siege of Arnhem starts, as Gelre desperately defends the city.
- 1445: Denmark-Sweden ends its aid to Holland and instead sends aid to Friesland. While the Siege of Arnhem ends quickly with a Gelre victory, Friesland now has the equipment to make their own push.
- 1448: Exactly ten years after the war started, Arnhem falls and the king of Gelre, Arnold I, is captured and imprisoned. He would die only a few months later.
- 1448-1452: For four years Holland and Friesland fought a bloody war mainly in the regions of Gelre and Utrecht, which are heavily damaged, even resulting in the complete destruction of the cities of Veenendaal and Doetinchem. Shifting Danish-Swedish influence and aid was the cause for the length of the war.
- January: The final Danish-Swedish shift of aid takes place, with the aid now going to Holland. The main battles are fought in Gelre
- May: Holland has complete control over Gelre, as the Battle of Zwolle and the Battle of Deventer are fought, with the Battle of Zwolle ending in a Hollander victory.
- June: The Battle of Deventer ends in the favor of Holland. The Frieslander army is largely destroyed and what is left is order to dig itself in at the borders.
- July: The Hollander army smashes through the Frieslander line of defence, and the men that survive flee to safer places. The sieges of Leeuwarden and Heerenveen end quickly, and the final Siege of Groningen ends on 18 July, signaling the start of the Republic of the United Netherlands.
