King Magnus sends a ship (or ships)…

King Magnus VII leaves Norway to his son and successor, Haakon VI, in 1355; he lives hereafter in Sweden, where he will fight constantly with the powerful aristocracy.

Charles meets with sharp resistance when he seeks to codify Bohemian law in the Majestas Carolina of 1355.

He will find it expedient after this point to scale back his efforts at centralization.

Louis sends reinforcements to Casimir III to fight against the Lithuanians, and Hungarian troops support Albert II, Duke of Austria, against Zürich.

The Venetian delegates offer Louis between six and seven thousand golden ducats as a compensation for Dalmatia, but Louis refuses to give up his plan to reconquer the province.

He signs an alliance with Albert II of Austria and Nicolaus of Luxemburg, Patriarch of Aquileia, against Venice.

John V in 1355 forcibly retakes the territories controlled by Kantacouzene family members.

John VI Kantakouzenos himself becomes a monk, although he continues to advise the government.

John VI Kantakouzenos, having abdicated the imperial throne, retires to a monastery in Mistra, in the Morea, where he will write his memoirs, a valuable source for the history of the period from 1320 to about 1357.

Dushan's son and successor ascends the Serbian throne as Stephen Urosh V, under whom the Serbian empire rapidly collapses.

Rival nobles divide Serbia; …

… control of Durazzo passes to the Albanian family of Thopias.

Croatian lords, acting on King Louis’s orders, besiege and capture Klis, a Dalmatian fortress that Stephen Dušan's sister, Jelena, had inherited from her husband, Mladen Šubić.

The English resume the offensive against the French with a damaging raid on the Languedoc.

The Great Raid of 1355 cripples southern France economically, and provokes resentment of the French throne among French peasantry.

The raid also 'cushions' the area for conquest, opens up alliances with neighbors in Aquitaine, the one with Charles II of Navarre being the most notable, and causes many regions to move towards autonomy from France, as France is not as united as England.

Charles had crossed the Alps without an army, received the Lombard crown in St. Ambrose Basilica, Milan, on January 5, 1355, and is crowned emperor at Rome by a cardinal in the April of the same year.

His sole object appears to have been to obtain the Imperial crown in peace, in accordance with a promise previously made to Pope Clement.

He only remains un the city for a few hours, in spite of the expressed wishes of the Roman people, and evinces no desire to recover already lost Italian jurisdictions.

Having virtually abandoned all the Imperial rights in Italy, the emperor re-crosses the Alps, pursued by the scornful words of Petrarch, but laden with considerable wealth.
