 The "Armenian Question" is a high school subject in some schools of Armenia.Beginning in the mid-19th century, the Great Powers took issue with the Ottoman Empire's treatment of its Christian minorities and increasingly pressured it to extend equal rights to all its citizens.Following the violent suppression of Christians in the uprisings in Bosnia and Herzegovina, Bulgaria, and Serbia in 1875, the Great Powers invoked the 1856 Treaty of Paris, claiming it provided the authority for their intervention to protect the Ottoman Empire's Christian minorities.
