The Ottoman Empire has achieved one of the greatest and most powerful civilizations of the modern history. The Ottoman glory in the sixteenth and seventeenth century represents one of the heights of human creativity, optimism, and artistry. In particular the administration system that they have adopted and employed draws admiration of most world statesmen.Ottomans called Istanbul "Konstantiniye" that is the city of Constantine the Great. The name was changed to Istanbul after the first world war. One explanation often given for Istanbul was that "istanbul" was derived from Stamboul which is ' from … (ees teen poleen), "to the city." It is believed that Ottomans constantly overheard this phrase rising from behind the city walls at the time of their siege. From this it is likely that they formed the word Stamboul. This derivation is of course untenable. However Ottomans often retained original names of places that they had captured. It is such that where the name was too long, they dropped the first syllable, and contracted or abridged the last syllables. For instance from Thessalonica they made Selanik and from Constantinople they made Stamboul.The best city to see for the heritage of Ottoman Empire is Istanbul where you can see Ottoman Harem, Ottoman Art, Architecture and personal belongings of Ottoman Sultans.The empire they built was the largest and most influential of the Muslim empires of the modern period, and their culture and military expansion crossed over into Europe. Not since the expansion of Islam into Spain in the eighth century had Islam seemed poised to establish a European presence as it did in the sixteenth and seventeenth centuries. The Ottomans established an empire where Islamic traditions and culture were so strong that its roots and traces last to the current day in Europe (the Muslims in Bosnia are the last descendants of the Ottoman presence in Europe) and the Middle East. Despite being fundamentally an Islamic empire, the Christian communities living within the empire numbered to considerable proportions. The greater majority of these were eastern or orthodox Christians namely, Greeks and Armenians. In addition, sizable Jewish communities were also living in harmony with Muslims and Christians alike.Turkish and Islamic Art Museum is housed in the Ibrahim Pasha Palace, which is often claimed to be bigger and more impressive than Topkapy Palace. The palace has witnessed many weddings, feasts and celebrations as well as rebellions and turmoil, and also has been used by Ibrahim Pasha himself and other grand viziers of the time. The carpet section forms the richest collection not only in Turkey but also the world at large. Besides very rare Seljuk and Ottoman carpets there are prayer and animal figured rugs belonging to 15th and earlier centuries. You will see the carpets produced in Anatolia between the 15th - 17th centuries, known as "Holbein Carpet" in the West.
