The Ottoman Empire was once a strong transcontinental state, mostly located in the territory of modern Turkey. In fact, at its peak, the Ottoman Empire had subordinate lands in northern Africa as well as in the territories of present-day Bulgaria, Azerbaijan, the Persian Gulf regions, Hungary, Greece, and several other European countries. The Ottoman Empire existed for almost six and a half centuries, namely from 1299 to 1923.
The history of the Ottoman Empire involved the active conquest of new lands, and by the Middle Ages, the state was already actively entrenched in Europe, having conquered Constantinople. Although the state was Islamic, the active conquest of new territories created its multinational image, which also contributed to the political and economic development of the Empire.
As is clear, the Ottoman Empire existed for quite a long time, and its development occurred at the same time as the emergence of triangular transatlantic trade and the flourishing of European powers. However, the military might of the Ottoman Empire prevented the consolidating European states from penetrating eastward into the European and Asian continents, so the colonizers were forced to use only the single route of the slave trade.
The collapse of the Ottoman Empire occurred in 1923, a few years after the end of World War I. The fall of the Empire was due to several reasons, among them the low viability of such a state in the post-industrial era. The Empire had already lost most of its lands by World War I, and endless internal revolutions and civil uprisings were destroying political power from within. Eventually, in 1923, the Ottoman Empire was abolished, and the Republic of Turkey in the territories of the Empire was established.
