Empress Elizabeth died in 1762, when Paul was 8 years old, and he became crown prince with the accession of his father to the throne as Peter III. However, within a matter of months, Paul's mother engineered a coup and not only deposed her husband but, for a long time, was believed to have had him killed by her supporters. It was later found that Peter III probably died due to a fit of apoplexy when exerting himself in a dispute with Prince Feodor, one of his jailers. Some historians believe that he was murdered by a vindictive Alexei Orlov. After the death of Peter III, Catherine then placed herself on the throne in a surpassingly grand and ostentatious coronation ceremony, for which event the Russian Imperial Crown was crafted by court jewellers. The 8-year-old Paul retained his position as crown prince.
