Central Europe 1300-1350 (Chaos)

1301: Poland feels threatened by the Germans and the Przemyslids. The king tries to fight them to break free, so a coalition of the Teutonic Order, Bohemia, Moravia and the HRE under king Otto IV of Brandenburg forms against him. Andras III, last Arpad king of Hungary, dies. This leads to a difficult situation in Hungary.

1308: The war between Germans and Poles doesn't end in the latter's favor. The Teutonic Order acquires Pommerellen (OTL West Prussia, the Poles also call it Eastern Pomerania), Silesia becomes a German fief; the western third goes to Brandenburg, which already acquired the Lower Lausitz / Lusatia, the rest is divided between the two Przemyslid lands, Bohemia and Moravia.

1309: King Otto of the HRE dies, Heinrich VII of Luxemburg (same as OTL) becomes new king. He manages to be crowned as Holy Roman Emperor by the pope in 1312, becoming the first emperor since Friedrich II. Popes move to Avignon.

1310: Luzern and Zug join the Swiss. Polish king Boleslaw V toppled by discontent nobles, who elect Kazimierz III new king.

1313: Kazimierz III makes an "everlasting alliance" with the (in many ways still independent) rulers of Mazovia.

1314-16: Sedisvacancy - no pope elected.

1315: Great famine in Europe.

1320: Heinrich VII dies (later than IOTL), duke Ottokar (yes, he was named after Ottokar Przemysl) of Upper Bavaria and the Palatinate is elected new king.

1321: Some of the electors in Germany are not happy, and elect Waldemar of Brandenburg anti-king.

1326: Use of cannons in Europe first mentioned in a Florentine document.

1328: Waldemar of Brandenburg defeated at Ansbach by Ottokar. Brandenburg loses its influence in Pomerania.

1330: Pope Johannes (John) XXII bans king Ottokar. Florence acquires Lucca for 75000 florin (gold coins).

1333-36: Ottokar goes to Italy, is crowned Emperor in Rome - not by the pope, but by the head of the mighty Colonna family! Still being banned, he declares Johannes to be deposed and appoints an anti-pope, a certain Innocent IV.

1334: Zürich, Glarus and Bern join the Swiss.

1335: Heinrich of Tyrol dies without male heirs; Tyrol will fall to the house of Luxemburg, via his daughter who married into this house.

1336: Intrafamilial contract of the Przemyslids: King Otakar of Bohemia gets Moravia and all of Silesia, while Wenzel of Carinthia acquires Austria. He now governs all the German-speaking lands. Note that despite of their Czech name, the family of the Przemyslids is already more German than Czech, due to cultural influence and marriages with Germans. Uprising in Flanders against unpopular count Ludwig II under brewer Jakob van Artevelde.

1339: Venice starts expanding on the terra firma.

1340: Due to different developments, the Lower Bavarian line of the Wittelsbachs continues. Bavaria stays split.

1342: Clemens VI elected pope. He's the last recognizable pope from OTL.

1346: Great famine in Europe.

1347: Black Death does not hit Europe. From now on, there's not much this Europe have in common with that of OTL. Overpopulated Europe suffers under population pressure. Some states less than others - England, Poland and Scandinavia still have a low population and can rather afford to grow; Germans go to the East, Hungarians to Romania, Spanish and Portuguese kick out the Moors and settle in their places - but France and Italy suffer much.
