Its been a while since I've posted in this thread, so here goes.

On February 1, 1908 he survived an assassination attempt by radical republican assassins known as the Lisbon Regide. However, his son the crown prince was not so lucky, leaving King Carlos I in a state of depression for a number of years. His reign also saw Portuguese neutrality in the Great War (1914-1917).
Luís Filipe, Prince Royal of Portugal, who was killed on February 1, 1908 in the Lisbon Regicide. His death sent the Portuguese nation into a state of mourning and helped to largely discredit the Republican cause in Portugal, with the Portuguese Republican Party deciding not to launch an armed insurrection at their party congress in 1909.
