On 13 October 1981 Ali Khamenei was sworn in as president of Iran after Mohammad-Ali Rajai was killed in a bombing.

Context

Khomeini was Leader and commander-in-chief. The Iran–Iraq war was already underway. Neighbouring UN 598 is 1988.

4 June 1989 Leadership is later. UN 598 is 1988. The 1988 prison executions sit on the same presidency, stored separately.

The Supreme Leader of Iran is commander-in-chief and the highest constitutional authority. He does not write a US presidential strike order, an IAEA Board resolution, or a Hamas military plan. Presidents, the IRGC, and the Guardian Council implement and share specific files.

Why it matters

The path is social cohesion: a completed presidential succession after an assassination is a dated continuity instrument inside a revolutionary system.

What the sources establish

Office of the Supreme Leader of Iran carries the official instrument or communique. Reuters records the same dated act independently.

Established: 13 October 1981 presidential oath, independently reported.

Not established: that the office was a liberal presidency, or a unique later war coefficient from the ceremony.

Khomeini was Leader. He took the oath.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Ali Khamenei is sworn in as president of Iran, not a later speech about Ali Khamenei is sworn in as president of Iran.

Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Voters in a constrained field elected. Khomeini was Leader. He took the oath. That limit is the alternative to treating office-holding as authorship of every later series.
