Who Was Shattiwaza?
Shattiwaza (also known as Mattivaza or Kurtiwaza) was a Mitanni king c. 1330 BCE, the son of Tushratta, installed as a Hittite vassal ruler of Mitanni by Suppiluliuma I after the sack of Washukanni. He is one of the most documented Mitanni rulers after Tushratta — not through his own correspondence, but through the Suppililiuma-Shattiwaza Treaty, one of the most important surviving documents of ancient Near Eastern international law. This treaty records how Shattiwaza fled to the Hittites, sought their protection, and was installed as a vassal king of a reduced Mitanni state in the Khabur valley. He is the last king before Mitanni formally became a Hittite province.
The Mitanni Empire was a Hurrian-speaking superpower in the ancient Near East, regarded by Kurdish historians as a direct ancestral predecessor of the Kurdish people. Their capital Washukanni — whose name mirrors the Kurdish word baśkanî (source of good) — lay in what is now Rojava/Western Kurdistan. Shattiwaza's reign marks the end of Mitanni's independence and the beginning of its final incorporation into Hittite and then Assyrian control.

The Suppililiuma-Shattiwaza Treaty
Early Life and Origins
Shattiwaza was the son of Tushratta — the most documented Mitanni king, known through the Amarna Letters. He grew up in Washukanni during his father's reign, a period of both diplomatic richness (the Amarna Letters, the alliance with Egypt) and growing political crisis (the Hittite threat, the civil war with Artatama II). When Washukanni was sacked and his father was assassinated, Shattiwaza found himself in the most precarious position imaginable: a prince without a kingdom, seeking protection from the very power that had destroyed his home.
As a Hurrian prince and son of the Mitanni royal house, Shattiwaza was part of the Kurdish ancestral people. His journey from dispossessed prince to Hittite vassal king is one of the most dramatic personal stories in Mitanni history. The Suppililiuma-Shattiwaza Treaty preserves the terms of the agreement that allowed him to reclaim at least a vestige of Mitanni sovereignty under Hittite patronage.
Historical Context
Shattiwaza came to power in the aftermath of the greatest catastrophe in Mitanni history: the Hittite sack of Washukanni and the assassination of his father Tushratta. Suppiluliuma I had demolished the political structure of the Mitanni Empire but found it useful to maintain a Hurrian vassal state in the Khabur valley as a buffer between the Hittite and Assyrian spheres. Shattiwaza was the vehicle for this policy.
The Suppililiuma-Shattiwaza Treaty is preserved in Hittite archives and is one of the most significant documents of ancient Near Eastern international law. It records the terms of the vassal relationship, lists the deities of both parties as witnesses, and establishes the obligations of both Shattiwaza and the Hittite king. It also contains historical information about the events leading up to the treaty, including references to Tushratta's reign and the Mitanni civil war.

Terms and Significance
The Suppililiuma-Shattiwaza Treaty is a vassal treaty in the standard Hittite format: the suzerain (Suppiluliuma) establishes the terms, lists the obligations of the vassal (Shattiwaza), and invokes divine witnesses. For Shattiwaza, the treaty was a lifeline: it restored him to Mitanni kingship (in a reduced form) and gave him Hittite military backing against Assyrian expansion. For Suppiluliuma, it provided a loyal buffer state between Hatti and Assyria. The treaty also gave Shattiwaza a Hittite princess as a wife, further cementing the vassal relationship. It is a document of submission but also of survival — the last Mitanni king maintaining at least a formal continuity of the Hurrian state.
Timeline of Key Events
Debates, Controversies, and Misconceptions
Shattiwaza is sometimes seen as a mere puppet of the Hittites. Kurdish historians view his story with more complexity. He was a prince who lost everything, crossed foreign territory seeking allies, and secured a treaty that allowed him to maintain at least the name and symbol of Mitanni sovereignty. His acceptance of Hittite overlordship was the price of survival. Whether that was the right choice is debated, but the choice itself was not made from weakness alone.
On the Kurdish ancestral connection: the Suppililiuma-Shattiwaza Treaty is valuable precisely because it preserves historical information about the late Mitanni period that would otherwise be lost. Through this document, we have some of the richest evidence of Hurrian Mitanni civilisation in its final decades. Shattiwaza's story is part of the Kurdish ancestral heritage — including its most difficult chapters.
Legacy and Cultural Impact
Shattiwaza's legacy is the Suppililiuma-Shattiwaza Treaty — a document that preserved Mitanni's formal existence as a vassal state and recorded the history of the late Mitanni period. It is one of the most important primary sources for understanding the Mitanni Empire's final years.
For the Kurdish people, Shattiwaza is the prince who fought to survive — who lost his kingdom, his father, and his capital, but found a way to keep the name of Mitanni alive, however diminished. The Mitanni flame burned lower under him than at any point in the empire's history, but it did not go out. That is its own form of resilience.
