This thesis provides an overview of the history of the Ottoman wars in Europe, spanning from the fall of Constantinople in 1453 to the early 19th century. It explores the key military conflicts, political shifts, and social transformations that shaped the relations between the Ottoman Empire and the European powers over several centuries. Following the conquest of Constantinople, the Ottoman Empire embarked on a period of intense expansion into Europe, securing significant territorial gains in the Balkans and Central Europe. Pivotal battles, such as the Battle of Mohacs in 1526 and the Siege of Vienna in 1683, were turning points in the Ottoman campaigns, influencing the balance of power on the European continent. During this period, Europe witnessed the formation of various alliances aimed at curbing the Ottoman threat, leading to a series of prolonged wars and treaties that reshaped the political landscape of the region. This thesis also examines the internal changes within the Ottoman Empire, including administrative and military reforms implemented in response to increasing challenges and the decline in power relative to the European great powers. By analyzing economic, cultural, and religious aspects, this study investigates how these conflicts influenced the development of national identities and intercultural relations in Europe. In conclusion, this thesis highlights the long-term consequences of the Ottoman wars, including the weakening of the Ottoman Empire and the rise of the European powers, which laid the groundwork for political and social changes in the 19th and 20th centuries. This historical analysis offers a deeper understanding of the complex relationships between East and West and their enduring and irreversible impact on modern European history.
