He was a member of the Institutional Revolutionary Party (PRI) and is known for his role in modernizing Mexico's economy during his presidency. His administration focused on industrial growth and infrastructure development. However, Díaz Ordaz's presidency is also remembered for the tragic events of the Tlatelolco Massacre in 1968, where government forces suppressed student protests, resulting in numerous deaths.
