The story of Iran’s emergence as a nation and its evolving relationship with Israel is a saga of empires, revolutions, and ideological shifts that spans millennia. From the grandeur of the Persian Empire to the modern Islamic Republic, Iran’s journey has been one of resilience, cultural richness, and geopolitical complexity.
Its conflict with Israel, rooted in the
seismic changes of the 20th century, has escalated into one of the Middle
East’s most volatile rivalries, culminating in the open warfare we witness
today in 2025. This blog post traces Iran’s historical evolution and unravels
the threads of its decades-long antagonism with Israel, offering insights into how
ancient legacies and modern politics collide.
The Birth of a Nation: From Persia to
Iran
The land we now call Iran has been a cradle of civilization
for over 2,500 years, its history shaped by the rise and fall of empires that
left an indelible mark on global culture. The name “Iran” derives from the
Middle Persian Eran, meaning “land of the Aryans,” reflecting the Indo-Iranian
tribes who settled the Iranian Plateau around 2000 BCE. These tribes, including
the Medes and Persians, laid the foundations for one of history’s greatest
empires.
The Achaemenid Empire
(550–330 BCE): The First Persian Superpower
The Persian Empire’s story begins with Cyrus the Great, who
founded the Achaemenid Empire in 550 BCE. Uniting the Medes and Persians, Cyrus
conquered vast territories, from Anatolia to the Indus Valley, creating the
world’s first true superpower. His policies of tolerance—famously allowing the
Jews to return from Babylonian exile to Jerusalem—earned him admiration in the
Hebrew Bible. The Achaemenids, under rulers like Darius I, built a
sophisticated bureaucracy, a network of roads (the Royal Road), and grand
capitals like Persepolis. Their Zoroastrian faith, emphasizing good versus
evil, shaped Persian governance and culture.
The Achaemenid Empire fell to Alexander the Great in 330
BCE, but its legacy of centralized rule and cultural synthesis endured.
Persia’s identity as a distinct civilization, blending Iranian traditions with
influences from Mesopotamia and beyond, was firmly established.
Parthians and Sasanians
(247 BCE–651 CE): Persian Resilience
After Alexander’s death, Persia became part of the
Hellenistic Seleucid Empire, but Iranian identity reasserted itself under the
Parthian Empire (247 BCE–224 CE). The Parthians, skilled horsemen, resisted
Roman expansion and facilitated Silk Road trade. Their successors, the Sasanian
Empire (224–651 CE), restored Persian glory, reviving Zoroastrianism and
clashing with the Byzantine Empire. The Sasanians’ capital, Ctesiphon, became a
hub of art and learning, but their rule ended with the Arab-Muslim conquest in
651 CE, which introduced Islam to Persia.
Islamic Persia and
the Rise of a Distinct Identity (651–1501 CE)
The Arab conquest transformed Persia, integrating it into
the Islamic Caliphate. Over time, Persians adopted Islam but retained their
language (Farsi) and cultural traditions. Under the Abbasid Caliphate (750–1258
CE), Persian administrators and scholars shaped Islamic governance and culture,
with works like Ferdowsi’s Shahnameh (c. 1000 CE) cementing Persian identity.
Independent dynasties like the Samanids and Buyids revived Persian governance,
while the Seljuk and Timurid empires blended Turkic and Persian elements,
fostering a cultural renaissance.
The Safavids
(1501–1736 CE): The Birth of Modern Iran
The Safavid Empire, founded by Shah Ismail I, marks the
origin of modern Iran. By establishing Twelver Shi’ism as the state religion,
the Safavids distinguished Iran from its Sunni neighbors, the Ottomans and
Mughals. Shah Abbas I (r. 1588–1629) modernized the state, built the splendid
capital of Isfahan, and strengthened Iran’s borders. The Safavid era solidified
Iran’s Shi’a identity, Persian language, and territorial cohesion—key elements
of the modern nation.
Qajars and Pahlavis
(1796–1979): Modernization and Upheaval
The Qajar Dynasty (1796–1925) faced challenges from European
imperialism, losing territory to Russia and Britain. The Constitutional
Revolution (1905–1911) introduced a parliament, signaling Iran’s push toward
modernity. In 1925, Reza Shah Pahlavi founded the Pahlavi Dynasty, centralizing
power, secularizing society, and renaming the country “Iran” in 1935 to
emphasize its ancient roots. His son, Mohammad Reza Shah, continued modernization
through the White Revolution (1963), but his authoritarianism and Western
alignment sparked dissent.
The Islamic Republic
(1979–Present): A Revolutionary Shift

The Islamic Revolution of 1979, led by Ayatollah Ruhollah Khomeini, overthrew the monarchy, establishing the Islamic Republic of Iran. This theocracy blended Shi’a Islam with republican elements, prioritizing anti-Western and anti-Israeli policies. Iran’s support for regional proxies like Hezbollah and Hamas, coupled with its nuclear ambitions, has defined its modern geopolitical stance, including its ongoing conflict with Israel.
Iran and Israel: From Allies to
Archenemies
The relationship between Iran and Israel has undergone a
dramatic transformation, from pragmatic alliance to open warfare. Understanding
this shift requires examining key historical moments and ideological divides,
particularly in light of the current war in 2025.
Pre-1979: An Unlikely Alliance
Before the Islamic Revolution, Iran and Israel were not
enemies; they were allies. In 1948, Iran, under the Pahlavi Dynasty, became the
second Muslim-majority country (after Turkey) to recognize Israel, driven by
shared strategic interests during the Cold War. Both nations sought to counter
Soviet influence and Arab nationalism, particularly from states like Egypt and
Iraq. Under Shah Mohammad Reza Pahlavi, Iran supplied Israel with oil,
especially after the 1967 Six-Day War, when Arab states boycotted Israel.
Israel, in turn, provided Iran with military training, agricultural expertise,
and intelligence cooperation, with Israel’s Mossad working alongside Iran’s
SAVAK. This partnership, part of Israel’s Periphery Doctrine to ally with
non-Arab states, was pragmatic but discreet to avoid antagonizing Arab
neighbors.
The Islamic Revolution (1979): A
Turning Point
The 1979 Islamic Revolution fundamentally altered
Iran-Israel relations. Ayatollah Khomeini’s regime severed diplomatic ties with
Israel, declaring it an “enemy of Islam” and the “Little Satan” (with the U.S.
as the “Great Satan”). Khomeini’s ideology framed Israel’s existence as
illegitimate, emphasizing support for Palestinians and rejecting the 1947 UN
Partition Plan, which Iran had opposed due to fears of regional instability.
Iran began backing Palestinian groups like Hamas and Islamic Jihad, as well as
Hezbollah, a Shi’a militia formed in 1982 with Iranian support during Israel’s
invasion of Lebanon.
This shift was rooted in revolutionary dogma: Khomeini
viewed Israel as a Western imperialist outpost and a usurper of Palestinian rights,
aligning Iran with the anti-Zionist cause to gain influence among Arab states.
Israel, meanwhile, saw Iran’s new theocracy and its support for militant groups
as a growing threat to its security.
1980s–2000s: The Shadow War
The Iran-Israel conflict initially played out through
proxies and covert operations, often called a “shadow war.” Iran supported
Hezbollah during the 1982 Lebanon War and funded Palestinian groups during the
First and Second Intifadas (1987–1993, 2000–2005). Israel responded with targeted
strikes, such as the 1981 bombing of Iraq’s Osirak nuclear reactor, which
indirectly aided Iran during the Iran-Iraq War (1980–1988).
Tensions escalated with Iran’s nuclear program, which began
under the Shah in the 1950s but intensified in the 1990s. Israel viewed Iran’s
pursuit of nuclear capabilities as an existential threat, fearing a potential
nuclear weapon. Covert actions intensified: the Stuxnet virus (2010),
attributed to Israel and the U.S., damaged Iran’s Natanz nuclear facility,
while Iran accused Israel of assassinating nuclear scientists between 2010 and
2012. Iran, in turn, armed proxies like Hezbollah, which clashed with Israel in
the 2006 Lebanon War, and supported Hamas in Gaza.
2010s–2023: Escalating Proxy
Conflicts
The 2010s saw Iran expand its regional influence through the
Axis of Resistance, a network of proxies including Hezbollah, Hamas, and
militias in Iraq and Syria. Israel countered with airstrikes in Syria and Iraq
to disrupt Iran’s arms supply lines to Hezbollah and prevent a “Shi’a corridor”
from Iran to the Mediterranean. Notable incidents include:
2011: Israel seized a ship carrying Iranian weapons to Gaza.
2012: Iran accused Israel of an explosion at its Isfahan
nuclear facility.
2015: A Swiss court ordered Israel to pay Iran $1.1 billion
for unpaid oil debts from the Pahlavi era, which Israel refused, citing Iran’s
status as an enemy state.
The 2015 Iran Nuclear Deal (JCPOA) heightened tensions.
Israel’s Prime Minister Benjamin Netanyahu called it a “historic mistake,”
arguing it failed to dismantle Iran’s nuclear program. When the U.S. withdrew
from the deal in 2018 under President Trump, Iran resumed uranium enrichment,
prompting Israel to intensify covert operations.
2023–2025: From Shadow War to Open
Conflict
The October 7, 2023, Hamas attack on Israel, killing 1,200
people, marked a turning point. Though Iran denied direct involvement, its
support for Hamas intensified regional tensions. Israel’s subsequent war in
Gaza, coupled with strikes on Iranian proxies in Lebanon, Syria, and Iraq,
weakened Iran’s Axis of Resistance. The assassination of Hamas leader Ismail
Haniyeh in Tehran (July 2024) and Hezbollah leader Hassan Nasrallah in Beirut
(September 2024), both blamed on Israel, prompted Iran to launch ballistic
missile attacks on Israel in April and October 2024.
By June 2025, Israel launched a major offensive against
Iran, targeting nuclear facilities, missile sites, and senior officials,
including nuclear scientists and Islamic Revolutionary Guard Corps (IRGC)
commanders. Iran’s foreign minister called it an “act of war,” and Iran
retaliated with missile and drone strikes, though most were intercepted. The
International Atomic Energy Agency (IAEA) condemned Israel’s strikes on nuclear
sites, citing violations of international law, but Israel justified them as
necessary to prevent Iran from developing nuclear weapons. As of June 2025, the
conflict has killed over 600 in Iran and 24 in Israel, with fears of further
escalation.
Why the Conflict Persists
The Iran-Israel conflict is driven by ideological,
geopolitical, and security factors:
Ideology: Iran’s post-1979 theocracy views Israel as an
illegitimate state and a symbol of Western imperialism. Supreme Leader
Ayatollah Ali Khamenei has called Israel a “cancerous tumor” and predicted its
destruction within 25 years (2015). Israel, in turn, sees Iran’s rhetoric and
proxy support as an existential threat.
Nuclear Ambitions: Israel fears Iran’s nuclear program could
produce a weapon, a concern heightened by Iran’s enrichment to 60% uranium
purity (2021) and IAEA reports of non-compliance in 2025.
Regional Power: Iran’s Axis of Resistance challenges
Israel’s regional dominance, while Israel’s strikes aim to disrupt Iran’s
influence in Syria, Lebanon, and beyond.
U.S. Involvement: The U.S., a key Israeli ally, has shaped
the conflict through sanctions, the JCPOA, and military support. Trump’s
withdrawal from the nuclear deal and the 2020 killing of IRGC commander Qasem
Soleimani escalated tensions.
Insights for Today’s War
The current Iran-Israel war, unprecedented in its
directness, reflects a culmination of decades of mistrust. Israel’s 2025
strikes, targeting Iran’s nuclear and military infrastructure, exploit the
weakening of Iran’s proxies (Hamas, Hezbollah, and Assad’s regime in Syria) and
aim to neutralize its nuclear threat. Iran’s retaliatory missile barrages,
though largely intercepted, signal its determination to resist despite domestic
economic struggles and international isolation.
Historically, Iran’s emergence as a Shi’a powerhouse under
the Safavids and its revolutionary turn in 1979 set the stage for its
anti-Israel stance. The Pahlavi era’s alliance with Israel shows that
cooperation was once possible, but Khomeini’s ideology and regional ambitions
made conflict inevitable. Today’s war risks drawing in the U.S., regional
powers, and global markets, with oil prices and nuclear proliferation as major
concerns.
Yet, history offers a glimmer of hope: Iran’s pragmatic
concessions during crises (e.g., the JCPOA) suggest diplomacy could avert total
war. For now, the Middle East stands at a crossroads, where ancient Persian
resilience meets modern geopolitical brinkmanship.
What’s Next?
As the Iran-Israel conflict unfolds, its outcome will shape
the Middle East’s future. Will the US-Qatar backed ceasefire lead to the end of
this conflict? Can diplomacy, perhaps led by the U.S., halt the cycle of
violence? Share your thoughts in the comments, and stay tuned for updates on
