Who founded the Sassanid dynasty by seizing Persia?

The Sassanid dynasty was founded by Ardashir, who is known for his military prowess and strategic acumen. He rose to power by successfully defeating the last ruler of the Parthian Empire, Artabanus IV, in a series of conflicts. This victory allowed him to establish a new dynasty that would bring about significant cultural and political changes in Persia, marking a shift from the Hellenistic influences of the previous era back to a more Persian-centric governance. Ardashir's reign is often characterized by efforts to restore the ancient glory of the Persian empires and promote Zoroastrianism as the state religion. His foundation of the Sassanid dynasty initiated an era that would last for over four centuries, making it a pivotal moment in Iranian history.
