HH Sheikh Nawaf Al-Ahmad Al-Jaber Al-Sabah was sworn in as the new Emir of Kuwait today, 30 September 2020, following the death of his half-brother, Sabah Al-Ahmad Al-Jaber Al-Sabah, the day before. Sabah had reigned since 2006.
I have therefore updated my Longest reigns page tonight. I might update the page soon, as I expect that the new Crown Prince will be designated in a not too distant future. I am not too happy with the way some of the sources are listed on the website, so I might do a make-over at the same time.
