The system of selective college admissions, for the most part, is based on tests geared to favor US middle- and upper middle class students, not students of the working class, or of different cultures, who may not have had comparable opportunities (Sternberg, 2004).
A powerful sultan in the Ottoman Empire was Mehmet II also known as Mehmed the Conqueror. He ended the Byzantine Empire and conquered Constantinople (which was then the capital of the Ottoman Empire). Mehmed is still considered a highly influential and inspirational figure in modern-day Turkey and many sites around the country are named after him.
After conquests in the Balkans by Murad I between 1362 and 1389, the Ottoman sultanate was transformed into a transcontinental empire and claimant to the caliphate. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror.
