Reis (sometimes spelled Rais) was a Turkish military rank akin to that of a naval captain, that was commonly added to the officer's name as an epithet. Examples include:
The rank Reis Pasha referred to an Admiral,[citation needed] while the Kapudan Pasha (akin to Grand Admiral; literally "Captain Pasha") title referred to the commander-in-chief of the Ottoman Navy fleet.
