The history of Ottoman Bulgaria spans nearly 500 years, beginning in the late 14th century, with the Ottoman conquest of smaller kingdoms from the disintegrating Second Bulgarian Empire. In the late 19th century, Bulgaria was liberated from the Ottoman Empire, and by the early 20th century it was declared independent.
The brutal suppression of the Bulgarian April Uprising of 1876 and the public outcry it caused across Europe led to the Constantinople Conference, where the Great Powers tabled a joint proposal for the creation of two autonomous Bulgarian vilayets, largely corresponding to the ethnic boundaries drawn a decade earlier with the establishment of the Bulgarian Exarchate.
