What Led to the Bosnian Crisis of 1908?
The 19th century was a period of continuous change and competition in Europe. Not only was it the height of European imperialismWhen powerful nations expand their control over weaker territories, usually for political or economic gain., but it also saw the rise of nationalism, which swept across the continent. For instance, Italy formally unified as a country in 1861, and Germany did the same in 1871. In both cases, smaller kingdoms unified into one larger country and saw the people of each country identify with each other nationalistically. This wave of nationalismA strong feeling of pride and loyalty toward one’s country or ethnic group, often driving people to unify or seek independence. also swept across the Balkans.
For centuries, much of the Balkans was ruled by the Ottoman Empire. The Ottoman Empire dated back to around the year 1300 and at its height stretched across the Middle East, Northern Africa, and large sections of Europe. It was a Sunni Islamic state that was based mainly out of modern-day Turkey. For example, the capital of the Ottoman Empire was the city of Constantinople, which today is called Istanbul. While the Ottoman Empire ruled over the Balkans for centuries, by the early 20th century, it was beginning to lose power over the region. This became most evident in 1908 when Austria exerted its influence in the Balkans with the Bosnian Crisis of 1908.​
