The Ottoman Empire's decline in the 19th century marked a turning point in Middle Eastern history. Internal challenges and European imperialism weakened the once-mighty empire, leading to territorial losses and reforms that struggled to modernize the state. European powers capitalized on Ottoman weakness, expanding their influence through economic penetration and military interventions. This shift reshaped the region's political landscape, setting the stage for the emergence of new nation-states and ongoing conflicts that continue to shape the Middle East today.
