Türkenkriege
The Muslim conquests were a military expansion on an unprecedented scale, beginning in the lifetime of Muhammad and spanning the centuries, down to the Ottoman wars in Europe. Until the 13th century, the Muslim conquests were those of a more or less coherent empire, the Caliphate, but after the Mongol invasions, expansion continued on all fronts (other than Iberia which was lost in the Reconquista) for another half millennium until the final collapse of the Mughal Empire in the east and the Ottoman Empire in the west with the onset of the modern period.
