===January &ndash; March===
* [[January 6]] &ndash; [[Henry VII, Holy Roman Emperor|Henry VII, the future Holy Roman Emperor]], is crowned [[King of Italy]] in [[Milan]] with a mock-up of the [[Iron crown]] of [[Lombardy]]. The Tuscan Guelphs refuse to attend the ceremony and begin preparing for resistance against Henry's rule. Henry approves the despotic regimes of [[Matteo I Visconti]] in Milan and [[Cangrande I della Scala]] in [[Verona]]. The cities of [[Piedmont]] and Lombardy submit to Henry – in accordance with the proclaimed program of peace and justice. [[Florence]] and their Guelph (anti-imperialist) allies in [[Tuscany]] and [[Romagna]] move to defend themselves against Henry's accession.<ref name="Jones">Jones, Michael, ''The New Cambridge Medieval History, Vol. VI: c. 1300-c. 1415'', Cambridge University Press, 2000.
