Now the Western world's drink du jour, coffee was first brewed in Yemen around the 9th century. In its earliest days, coffee helped Sufis stay up during late nights of devotion. Later brought to Cairo by a group of students, the coffee buzz soon caught on around the empire. By the 13th century it reached Turkey, but not until the 16th century did the beans start boiling in Europe, brought to Italy by a Venetian trader.
It is said that algebra was developed in the Yemen city of Zabid.

Firstly empires are not people and therefore they do not invent things. Secondly inventing things is what people do, whether Roman or not.
They design things to be invented, but do not invent their own thing.
