The May Coup was a coup d'état which resulted in the assassination of King Alexander I of Serbia and his consort, Queen Draga, inside the Royal Palace in Belgrade on the night of 10–11 June [O.S. 28–29 May] 1903. This act resulted in the extinction of the Obrenović dynasty that had ruled the Kingdom of Serbia since the middle of the 19th century. A group of Royal Serbian Army officers led by Captain Dragutin Dimitrijević (Apis) organized the assassination. After the May Coup, the throne passed to King Peter I of Serbia.

Natalija Obrenović, née Keshko, known as Natalie of Serbia, was the Princess of Serbia from 1875 to 1882 and then Queen of Serbia from 1882 to 1889 as the wife of Milan I of Serbia.
