Various forms of what is today the Suez Canal existed in Egypt between 1850 BCE and 775 CE, although primarily to facilitate trade between the Nile River Delta and the Red Sea. Between 1859 and 1869, Egyptian khedive Saʿīd Pasha partnered with France’s Suez Canal Company to build the present canal connecting the Mediterranean and Red seas.
