 The PUK traces its political heritage to Sulaymaniyah native Ibrahim Ahmad.After the collapse of the Soviet-backed Kurdish Mahabad Republic in Iran in early 1947, Ibrahim Ahmad, previously the Sulaymaniyah representative of the Iranian KDP (KDP-I), joined the newly formed Iraqi KDP.Ahmad was a highly influential leftist intellectual, who by 1951 had succeeded in rallying most of the Iraqi Kurdish leftist-nationalists to the new Iraqi KDP, which, in turn, took the opportunity to convene a second Party Congress and duly elect Ahmad as secretary-general (effectively acting Chairman).
