Under the Peshwas, the Maratha kingdom developed as a very successful military organisation. They built strong forts to face the Mughals. Between 1720 and 1761, the Maratha Empire expanded. It gradually occupied the parts of the Mughal Empire. Malwa and Gujarat were seized from the Mughals by 1720s. By the 1730s, the Maratha kingdom was enjoying complete domination in the entire Deccan.
