Thanks lauragarnet and johnnycb09. Sorry for my English I hope you will understand me.
I also think It could be from Ottoman empire (if it is original). I am from Croatia.

I found this on internet:

"The Hundred Years' Croatian–Ottoman War is the name for a sequence of conflicts, mostly of relatively low-intensity,between the Ottoman Empire and the medieval Kingdom of Croatia (ruled by the Jagiellon and Zápolya dynasties), and the later Habsburg Kingdom of Croatia.

Pope Leo X called Croatia the Antemurale Christianitatis in 1519,[6] given that Croatian soldiers made significant contributions to the struggle against the Turks. The advancement of the Ottoman Empire in Europe was stopped in 1593 on Croatian soil (Battle of Sisak), which could be in this sense regarded as a historical gate of European civilization. Nevertheless, the Muslim Ottoman Empire occupied parts of Croatia from the 16th to the end of the 17th century"

 

Cannot begin an assessment until seeing entire item and knowing dimensions. What I see in the one photo appears to be no earlier than 20th C. Blade does not look like that of a forged steel sword either on the surface of the metal or the shape of the surface.

 

The lenght of the sword is 25.6 in.
I found it in my grandfather's attic
Maybe it is replica

 

Still need overall photos. Agree with replica based on limited info we have so far.
