Answer :
Final answer:
The decline of the Ottoman Empire fueled Slavic nationalist movements in the Balkan region, leading to Pan-Slavism and increased tensions in the early 20th century.
Explanation:
The decline of the Ottoman Empire most influenced the growth of Slavic nationalist movements in the Balkan region during the late 1800s and early 1900s. As the Ottoman Empire weakened, various ethnic groups in the Balkans sought independence, leading to nationalist tensions and movements.
One example of nationalist sentiment was Pan-Slavism, a movement backed by Russia to unite Slavic peoples and challenge Austria-Hungary's authority in the Balkans.
In 1908, the Austro-Hungarian takeover of Bosnia escalated tensions, deepening alliances between Serbs, Bulgarians, and Russians against Austro-Hungarian influence.
