I don't know whether this question might be too "Tuesday Trivia" to be allowed here, but for what it's worth, allegedly, the first shah of the Sassanid/Neo-Persian Empire, Ardashir, personally killed the last shah of the Arsacid/Parthian Empire, Artabanus V. Ironically, he did it with an iconic Parthian combat technique -- drawing an enemy into pursuit with feigned flight, then turning around and shooting the pursuing foe with a bow.

This submission has been removed because it violates the rule on poll-type questions. These poll-type questions do not lend themselves to answers with a firm foundation in sources and research, and the resulting threads usually turn into monsters with enormous speculation and little focussed discussion. “Most”, “least”, "best" and "worst" questions usually lead to vague, subjective, and speculative answers.
