Ottoman empire in its weakened state, it has got the name as “Sick man of Europe”
Step-by-step explanation:
The Ottoman Empire was one of the powerful empires, just because it had the control over the trading city 'Constantinople' which acted as the bridge for trade between the Europe and The mighty Asia.
Many wars took place over the same place and in fact it was one of the reasons for the fall of this mighty empire in the nineteenth century. Once a great empire turned to a weakened state, he was started to be referred as the “Sick man of Europe”.
