The Investiture Controversy was a pivotal 11th-century conflict between King Henry IV of Germany and Pope Gregory VII over whether secular rulers or the papacy held authority to appoint church officials. The dispute led to Henry’s excommunications, political turmoil, and civil war within the German kingdom, symbolized by his famous penance at Canossa in 1077. Although the conflict was not resolved until 1122, it reshaped the relationship between church and state and sparked enduring debates about the limits of religious and secular power.Written by Emily Lovett.

The Ottoman Empire’s end was not a single event but the culmination of a decade of wars, displacement, ethnic violence, and political upheaval between 1911 and 1923. These conflicts, especially World War I, devastated the empire, contributed to the Armenian genocide, shattered long-standing multiethnic coexistence, and fueled nationalist movements that led to the abolition of the Ottoman dynasty. Following the nationalist victory under Mustafa Kemal Atatürk, the 1923 Treaty of Lausanne replaced the Treaty of Sèvres, secured international recognition for the new Republic of Turkey, and reshaped the modern Middle East through new borders and a massive forced population exchange.Written by Yiğit Akın.
