Explanation:
1.The Ottoman Empire was founded in Anatolia, the location of modern-day Turkey. Originating in Söğüt (near Bursa, Turkey), the Ottoman dynasty expanded its reign early on through extensive raiding. This was enabled by the decline of the Seljuq dynasty, the previous rulers of Anatolia, who were suffering defeat from Mongol invasion.
2.There are many reasons as to why the empire was as successful as it was, but some of them include its very strong and organized military and its centralized political structure. These early, successful governments make the Ottoman Empire one of the most important in history.
