This is a busy time of the year for commemorations of tragic royal anniversaries. On this date in 1908, King Carlos I of Portugal (b 1863) and his son and heir Dom Luiz Filipe (b 1887) were assassinated in Lisbon by republican revolutionaries. The monarchy under younger son Manoel II (1889-1932) survived only two more years.
See the excellent Portuguese monarchist site Memorial do Regicidio for footage of the funeral and more. Fellow royalist blogger Jørn K. Baltzersen notes the anniversary here.
May the people of Portugal soon renounce the bloodstained error of republicanism and restore Dom Duarte III to the throne!
