The stagnation visible in the intellectual field was paralleled in the military sphere as well. Babar had introduced Gunpowder in India, but after him there was no real improvement in military equipment of the Mughuls. No real progress or large scale training of local personnel in the use of artillery was made or undertaken in Mughul in India and the best which they could do was to higher foreigners for their artillery.
With their condition of the Mughul army, the downfall of the Muslim ruler was only a question of time. The ambitious mansabdars who were allowed to maintain an army for the emperor used it for the consolidation of their own power and thereby reduction the authority of the emperor. The invasions of Nadir Shah destroyed the prestige of the Mughul army and never afterwards it could regain its strength.
