Tahmasp II
Nader's first Ottoman Campaign was his first against perhaps his most formidable of adversaries, namely the Ottomans, where he proved triumphant in conquest. The great successes of his expedition, however, were rendered null when Shah Tahmasp II decided to take personal command of the theatre in Nader's absence, forcing a furious Nader to return and rectify the situation after forcing Tahmasp's abdication in favour of his infant son Abbas III.
