The Ottoman Empire secured its place as one
of the most powerful and large empires throughout its 600 years of history. It was the empire that seized Constantinople
and collapsed the Byzantine Empire, and its cultural expansion still remains throughout
some of its former vassal states today. But, there will always be curiosity as to
why any empire stopped where it did, and what prevented further growth before the ultimate
collapse. In the case of the Ottomans, one question
that comes to mind is why didn’t the Ottomans conquer Persia?... There are a few major factors that contributed
to why Persia, now Iran, never became a part of the Ottoman Empire. Firstly, the topography of the region between
modern-day Turkey and Iran posed an irreversible challenge. Despite the two nations sharing a border,
the land between the empires was full of mountain ranges and desolate valleys. Access to freshwater was minimal and the journey
from Constantinople and into Persia, a particularly large territory as well, would have utterly
exhausted the Ottoman troops. Even if they could have supplied themselves
well enough to successfully make the trek, by the time they arrived at their destination,
they would have been fatigued. Any harassment or guerilla tactics from the
Persians would have put an overwhelming amount of pressure on the Ottomans. In the case that somehow the latter was able
to reach their goal destination unseen, they would have needed significant rest before
battle, and after the fact, would still have to march all the way back home. Such a rough journey would have then made
it easy for the Persians to retake any lost territory as the depleted Ottoman forces made
their way back to Constantinople. It simply would have been nearly impossible
to have any success with such difficult terrain and distance to overcome. Nonetheless, the Ottomans and Persians were
staunch adversaries due to religious disputes. The Ottomans were Sunni Muslims while the
Persians, particularly the once magnificent Safavids, were Shi’ite Muslims. This meant that, regardless of the odds being
stacked against the Ottomans, they actually did try to take on the Persians not once,
but multiple times, in a series of Ottoman-Persian Wars beginning in the 16th century. So, let’s take a look at why the Ottoman
Empire failed to conquer Persia each time that they took on the empire... The first clash between the Ottomans and Safavids
came in 1514 at the Battle of Chaldiran and was fought on the soil of Iranian Azerbaijan. Selim I had just taken control of the Ottoman
Empire after a succession dispute and feared that a growing Shi’ite militia group who
had supported his rivals would now stir up a new conflict in the name of the Safavid
Shah, Ismail. In response, Selim declared war on the Persians
and began a march into Eastern Anatolia. Predictably, the draining trek quickly began
to reduce the morale of the Ottoman troops, in addition to the uneasiness from many who
did not like the idea of going to war with fellow Muslims. Meanwhile, alerted of the declaration, Ismail
worked to wrap up his current conflict in the east against the Uzbeks in hopes of avoiding
a two-front war. The Safavids finally arrived in Chaldiran
after enacting a scorched-earth policy in the west to weaken the Ottoman advance, and
just as the Janissaries began to express their clear discontent with Selim and the overall
campaign. The armies eventually clashed on August 23,
and more advanced weaponry, planning, and training carried the Ottomans to victory and
a few weeks later, to the Safavid capital of Tabriz which they raided and captured. They next seized territories in northern Mesopotamia
and Eastern Anatolia and may have pushed even further into Persia if not for growing frustrations
from within the Janissaries. Selim subsequently opted to return to Constantinople
to appease his men, and while victory was obtained, it was clear already that the journey
into Persia would not be an easy obstacle for the Ottoman troops to overcome if extended… Next came the Ottoman-Safavid War of 1532
through 1555. This time the conflict began from mutual territorial
disputes and included an effort from the Persians to form an alliance with the Europeans, particularly
the Habsburgs, to try and correlate an attack on the Ottomans from both sides at once. Still, the Ottomans found quick success as
they attacked Safavid Iraq and recaptured the Safavid capital. Catching wind of the Habsburg-Persian alliance,
the Ottomans now formed friendly ties with the Habsburg rivals in France and formed a
Franco-Ottoman alliance, which led to further Ottoman expansion in Eastern Anatolia and
the surrounding Persian territories, with the help of a French ambassador. The war was eventually concluded with the
Peace Treaty of Amasya, which confirmed most of the Ottomans’ territorial gains but did
return Tabriz to the Safavids. While this war was yet again a triumph for
the Ottoman Empire, they were so far unsuccessful in taking any Persian lands within modern-day
Iran aside from the temporary claims to the capital. Pushing deeper into Persia remained too taxing… Nonetheless, in 1578, another war broke out
between the Ottomans and Safavids after the Uzbeks reached out to the Ottomans to offer
a collaboration that would force the Safavids to fight a two-front war once more. Despite hesitation from the Sultan, once the
Uzbeks made their move, the Ottomans followed by attacking the Safavid-controlled Caucasus. Once again, they managed to seize Tabriz and
also captured multiple Caucasian towns along the way. The Safavids were struggling to maintain both
fronts but found a streak of luck when the Uzbeks were forced to withdraw to deal their
own political issues elsewhere. This triggered some of the formerly conquered
rulers under the Ottomans to defect to the Safavids, but none of this was enough to slow
the Ottoman momentum, and by the conclusion of the war with the Treaty of Istanbul in
1590, Safavid territories in the Caucasus, Anatolia, Mesopotamia, and parts of the west
of Persia had all fallen to the Ottomans. Still, it’s important to note that Ottoman
progress stayed in the west of Persia, just across their own border. Further campaigns going deeper into today’s
Iran had yet to materialize, likely due to the practicality of it… Angered anyway by the Ottoman’s recent consolidation,
the Safavids now attacked their rival in 1603 with the goal of recapturing their lands while
the Ottoman Empire was stretched thin by internal conflicts, the Jelali revolts, and the Thirteen
Years’ War. The conflict this time raged on until 1618,
generally considered to have occurred in two stages, and resulted in the successful recapture
of part of the Safavid’s old territories in the Caucasus and Persia itself… Throughout the 1700s, repetitive battles continued
to break out between the Ottomans and Safavids and then the Ottomans and Afsharid Persian
Empire and Zand Dynasty, but still, no real progress could be made on behalf of Ottoman
expansion deeper into Persia. The final major conflict came in the Ottoman-Persian
War of 1821 through 1823, and pitted the Ottomans against the Persian Qajar Empire. The warfare mostly occurred around Eastern
Anatolia and the Turkish-Persian border, which again meant that the Ottomans did not attempt
to go farther into Persia for a real conquest. The result of this final clash was pretty
lackluster and no territorial changes were even made. Additionally, by this point, conflict with
the nearby European powers was increasing and the centuries of Ottoman-Persian Wars
had taken its toll on both sides… This was also the final century of the Ottoman
Empire’s existence. Becoming known as “the sick man of Europe”,
the Ottomans were in no position to try and undertake such a massive invasion by now,
and especially one that would be as tiring as a Persian conquest would be. There was simply no motivation nor opportunity
to do so at this point, and previously, there lacked a proper chance as well. The Ottoman-Persian Wars demonstrated Persia’s
ability to fight off the Ottoman Empire even just at the border, and in some instances
even showed clearly how the Janissaries felt about the difficult journey just to enter
Persia, particularly when the Persians used a scorched earth policy as they often did
against the Ottomans. The religious rivalry and other factors that
may have motivated the Ottomans to want to try and capture Persia just would not have
been enough to overcome the reality of the situation. The terrain was too hard to trek for long
periods and with insufficient supplies, it was nearly impossible to enter Persia in such
a way that the Ottoman forces would be able to rest before clashing with any Persian troops,
it would have been almost a waste entirely given the fact that the Persians could recapture
any seized territories as the Ottomans tried to navigate through the mountain ranges to
return home, and the Persians were not a weak nation under any of the empires and dynasties
that the Ottomans faced. This, on top of conflicts with the Europeans
overlapping and internal conflicts within the Ottoman Empire itself, all in all, made
a conquest of Persia very low on the list of risks the Ottomans should or would take. By the time the series of Ottoman-Persian
Wars ended, it was clear that even if there had been an opportunity for such an endeavor,
the time had passed and by now, the Ottomans would not conquer Persia…
