Answer: Constantinople
Explanation:
Byzantium has, for centuries, been a barrier to the overflow of Islam into Europe. Eventually, in 1453 it fell into the hands of the Ottomans. Islam spread from the east, and Constantinople was a barrier to further expansion. When Mehmed II conquered Constantinople, the city became the Ottoman capital, and it was from that administrative and political center that the Ottomans organized further military campaigns towards Europe. In this way, they also tried to spread Islam. There are several examples where they have succeeded in these endeavors. These examples are obvious in some countries of Southeast Europe.
Explanation:
Success can be defined as the accomplishment of an aim as per your standards. For example, some consider a happy relationship, successful career, health or fitness as a success while it may not be the same for others.
To measure success following points can be considered
- Choosing the path of Fulfillment: Living you were meant to live.
- Made a difference in someone's life i.e. improve the world around you
Wealth up to an extent means success but mere wealth is not a success. Working whole day tirelessly without any break can give you money but it apprehends your happiness.
