Wrong. Urdu existed since 11th century. Mughals bloomed it since it was chosen I've Farsi as official.kangisge.The word itself Ordu was brought by Turks ... to be specific Babur... Zuban-e-Ordu-e-Muala was the camp language... some mixture of Persian, Turkish and Arabic... Ordu Bazar was Camp Market ... that is when Moguls took over they applied this nomenclature to Delhi itself... where it didn't exist before... it is until later that the camp language mixed with existing Muslim discourse and took it's modern shape as Urdu... it is also important to note that Muslim academics were extremely partial against Khariboli and did want to associate themselves with it ... whereas today most people contend Khariboli as a prelude to Urdu itself... enough from me...
I created and posted a time line of evolution of Urdu right from the times of indo Aryan migration you should look it up in the search.
