In this paper, I want to address how the Ottoman military declined and went from being victorious in most campaigns, to being outclassed and defeated by European militaries in 1683, the 19th century, the Balkan Wars, and finally in WWI. I am attaching 5 sources but can provide additional sources in PDF as I have access to academic journals and book chapters through my university's elibrary. Sources must be scholarly. For books, consider materials published by a university press. For articles, consider peer reviewed materials from an academic journal.
