Answer:
The extent ( boundaries) of the Ottoman Empire grew larger from the 15th to the 18th century.
Explanation:
People from Central Asia have a history of advancing from life on the steppe to empire, including the Huns, Mongols, Bulgars, etc. After all, horse-mounted warrior civilizations were capable of great strength and efficiency. When they had decisive leadership to pull them together, they sometimes had epochs of being nearly unstoppable. The Ottoman Turks were the last of them to establish an empire. Their dominion stretched from Persia to the Arab world, North Africa, the Mediterranean Sea islands, and into Southeast Europe. They besieged Vienna when they were at their worst. The Ottomans faded during decades of conflict, including counterattacks and insurrections, as empires do. They had adopted the nickname "sick man of Europe" by the time World War I started. However, they still controlled a huge portion of Asia. Being on the wrong side led to their loss and the division of their empire into protectorates of the Allies and distinct nations. The residue is the country of Turkey today. Turkey under Kemal Mustafa (Ataturk) undertook a major modernisation and secular state building transition. Along with these changes, Ataturk also enacted several social reforms to reduce the presence of religion. These included closing several religious schools, introducing a new more secular education system, banning religious marriage and changing the language in the Qur'an and the call to prayer from Arabic to Turkish.
