 culture and history, ranging from triumphant and unchallenged ancient military supremacy affording effective superpower status in its day, to a series of near catastrophic defeats (beginning with the destruction of Elam) at the hand of previously subdued peripheral nations (including Greece, Arabia, and the Asiatic nomadic tribes at the Eastern boundary of the lands traditionally home to the Iranian people).

Achaemenid Era

The Achaemenid Empire (559 BC–330 BC) was the first of the Persian Empires to rule over significant portions of Greater Iran. The empire possessed a “national army” of roughly 120.000-150.000 troops, plus several tens of thousands of troops from their allies.

The Persian army was divided into regiments of a thousand each, called hazarabam.
Ten hazarabams formed a haivarabam, or division. The best known haivarabam were the Immortals, the King's personal guard division. The smallest unit was the ten man dathaba. Ten dathabas formed the hundred man sataba.

The royal army used a system of color uniform

s to identify different units. A large variety of colors were used, some of the most common being yellow, purple, and blue. But this system was probably limited to native Persian troops and was not used for their numerous allies.

The power of the early Parthian empire seems to have been overestimated by some ancient historians, who could not clearly separate the powerful later empire from its more humble obscure origins.

ic polity.

Most Muslim historians have long offered the idea that Persia, on the verge of the Arab invasion, was a society in decline and decay and thus it embraced the invading Arab armies with open arms. This view is not widely accepted however. Some authors have for example used mostly Arab sources to illustrate that "contrary to the claims , Iranians in fact fought long and hard against the invading Arabs." This view further more holds that once politically conquered, the Persians began engaging in a culture war of resistance and succeeded in forcing their own ways on the victorious Arabs.

"They used for arms, swords, lances, arquebuses, which all the soldiers carry and use; their arms are also superior and better tempered than those of any other nation. The barrels of the arquebuses are generally six spans long, and carry a ball little less than three ounces in weight. They use them with such facility that it does not hinder them drawing their bows nor handling their swords, keeping the latter hung at their saddle bows till occasion requires them. The arquebus is then put away behind the back so that one weapon does not impede the use of the other."

This picture of the Persian horseman, equipped for almost simultaneous use of the bow, sword, and firearm, aptly symbolized the dramatic and complexity of the scale of changes that the Persian Military was undergoing. While the use of personal firearms was becoming commonplace, the use of field artillery was limited and remained on the whole ineffective.

Following Nader Shah, many of the other leaders of the Afsharid dynasty were weak and the state they had built quickly gave way to the Qajars. As the control of the country de-centralised with the collapse of Nader Shah's rule, many of the peripheral territories of the Empire gained independence and only paid token homage to the Persian State.

The second half of the 18th Century saw a new dynasty take hold in Iran. The new Qajar dynasty made an attempt to form, and yet again modernise the Iranian military following the breakup of Nader Shah

This period marked a decline in Persia's power and thus its military prowess. From here onwards the Qajar dynasty would face great difficulty in its efforts, due to the international policies mapped out by some western great powers and not Persia herself. Persia's efforts would also be weakened due to continual economic, political, and military pressure from outside of the country (see The Great Game

These efforts to continue the modernisation of the army through the training of officers in Europe continued until the end of the Qajar dynasty.

 (See papers by Waibel and Esandari Qajar within the Qajar Studies source). Russia backed the Persian attacks, using Persia as a 'cat's paw' for expansion of its own interests. Britain feared the seizure of Herat would leave a route to attack India controlled by a power friendly to Russia, and threatened Persia with closure of the trade of the Persian Gulf. When Persia abandoned its designs on Herat, the British no longer felt India was threatened. This, combined with growing Persian fears about Russian designs on their own country, led to the later period of Anglo-Persian military co-operation.

Ultimately, under the Qajars Persia was shaped into its modern form. Initially, under the reign of Agha Mohammad Khan Persia won back control of several independent regions and the northern territories, only to be lost again through a series of bitter wars with Russia. In the west the Qajars effectively stopped Ottoman encroachment and in the east the situation remained fluid. Ultimately, through Qajar rule the military institution was further developed and a capable and regionally superior military force was developed. This was quashed by the then superpowers of the day: Russia and Britain.
