Geographical Location:
Iranians and Greeks come from the northwest because of their geographical location. Iran is located in the Middle East, bordered by Armenia, Azerbaijan, Turkmenistan, Afghanistan, and Pakistan to the north and east, and Turkey and Iraq to the west. Greece is situated in southeastern Europe, with Albania, North Macedonia, Bulgaria, and Turkey to the north. Both Iran and Greece are positioned in the northwestern part of their respective regions, which contributes to their shared historical and cultural influences.

Historical Migration Patterns:
Throughout history, there have been various migration patterns that have influenced the movement of people from different regions. The ancient Greeks were known for their seafaring skills and established colonies in various parts of the Mediterranean, including present-day Turkey and Italy. Similarly, Iranians have a long history of migration and conquest, with the Persian Empire once extending across a vast territory, including parts of modern-day Greece.

Cultural Exchange and Influence:
The proximity of Iran and Greece in the northwest has allowed for cultural exchange and influence over the centuries. The ancient Persian Empire had interactions with Greek city-states, leading to cultural exchanges in art, architecture, language, and philosophy. The conquests of Alexander the Great further solidified connections between the two regions, leaving a lasting impact on both Iranian and Greek cultures.

Shared Indo-European Roots:
Both Iranians and Greeks belong to the larger Indo-European language family, which suggests a shared linguistic and possibly genetic heritage. The Indo-European languages originated in the Pontic-Caspian steppe region in present-day Ukraine and southern Russia, spreading westward into Europe and southward into Iran and the Indian subcontinent. This common linguistic ancestry further reinforces the connection between Iranians and Greeks in the northwest.
