This book deals with the uniforms worn by the regular army of the Qajar era from 1807 to 1848. Crown Prince Abbas Mirza, governor of the Persian province of Azerbaijan, admired the military reforms of neighbouring Sultan Selim III and is historically regarded as an early moderniser of the Persian army, known as Nezam-e Jadid: Reforms of the New Order. The first modern Persian army, called Sarbaz: regular infantry, was trained according to the European model. With the expansion of the regular army from the 1840s onwards, during the era of Naser al-Din Shah, uniforms were simplified and, with the introduction of the tunic, which was popular in most European armies at the end of the Crimean War, and new headgear, which replaced the classic conical sheepskin cap of the Qajar with a busby cap based on European models. At the end of this book, there is a brief discussion of later developments in uniforms from the 1850s onwards and the uniforms after 1860, which continued to evolve into the 1890s. For the sake of completeness, the naval uniforms from the period 1860 to 1890 are also briefly presented.
