Infrastructure investments:

Ranjit Singh ensured that Panjab manufactured and was self-sufficient in all weapons, equipment and munitions his army needed. His government invested in infrastructure in the 1800s and thereafter, established raw materials mines, cannon foundries, gunpowder and arm factories. Some of these operations were owned by the state, others operated by private Sikh operatives.

However, Ranjit Singh did not make major investments in other infrastructure such as irrigation canals to improve the productivity of land and roads. The prosperity in his Empire, in contrast to the Mughal-Sikh wars era, largely came from the improvement in the security situation, reduction in violence, reopened trade routes and greater freedom to conduct commerce.
