Remarks:
Bulgaria became gradually the most advanced and formidable state in the Balkans. In 1908, at the time of the revolutionary crisis in Turkey and the annexation of Bosnia and Herzogovina by Austria, Ferdinand declared himself Czar of a completely independent Bulgaria.
Milan abdicated in 1889, and his son Alexander became King of Serbia. He and his wife were murdered in 1903 and Peter Karageorgevich accepted the crown.
