Seizure of Abu Musa and the Greater and Lesser Tunbs 1971 Iranian military seizure of islands in the Strait of Hormuz
In 1971, the Imperial Iranian Navy seized three strategically located islands in the Strait of Hormuz (Abu Musa, Greater Tunb, and Lesser Tunb) shortly after British military withdrawal, asserting control over critical maritime chokepoints. The geopolitical and maritime security implications affected regional stability, oil shipping lanes, and military logistics, with long-term consequences for Gulf State sovereignty and global energy markets. This event highlighted vulnerabilities in post-colonial power vacuums and the risks of underdefended territorial claims.
