Yazdegerd III ascends the throne as king (shah) of the Persian Empire. He becomes the last ruler of the Sasanian dynasty (modern Iran).
In 632, Yazdegerd III ascended the Persian throne as the last shah of the Sasanian Empire.
Yazdegerd III ascended the Persian throne in 632 at a young age after the death of his predecessor. He inherited a vast empire stretching from the Euphrates to the Indus. As the final monarch of the Sasanian dynasty, his reign was marked by internal strife and external threats from the emerging Islamic Caliphate. His youth and inexperience challenged his authority and strained relations with powerful nobles. During his rule, the empire faced repeated raids by Arab forces that eroded its stability. Despite efforts to rally resistance, the Sasanian state gradually weakened over the decade. Yazdegerd's eventual flight eastward signaled the end of centuries of Zoroastrian royal authority in Iran. His legacy endures as a symbol of the dynastic decline that transformed the region's history.

Sovnarkom establishes decree time in the USSR.
The Soviet government issues the decree time system, standardizing clock adjustments across the USSR.
On June 16, 1930, the Council of People's Commissars (Sovnarkom) of the USSR introduced 'decree time,' advancing clocks by one hour throughout Soviet territories. The policy aimed to maximize daylight hours for industrial and agricultural productivity under the Soviet five-year plans. By replacing traditional solar timekeeping, decree time reflected the centralized planning ethos of the era. The measure was applied uniformly and affected daily routines, work schedules, and transportation timetables. Over the years, decree time would be reversed, reinstated, and modified several times. It remained a distinctive aspect of Soviet life until standardized time zones were formally adopted.

The National Industrial Recovery Act is passed in the United States, allowing businesses to avoid antitrust prosecution if they establish voluntary wage, price, and working condition regulations on an industry-wide basis.
The US passes the National Industrial Recovery Act, permitting industry codes and labor regulations under the New Deal.
On June 16, 1933, President Franklin D. Roosevelt signed the National Industrial Recovery Act (NIRA) into law as a cornerstone of the New Deal. The act empowered industries to form voluntary codes governing wages, production levels, and working conditions to combat deflation and unemployment. In exchange for compliance, participating businesses received exemptions from antitrust lawsuits. NIRA also established the Public Works Administration to fund large-scale infrastructure projects and stimulate job creation. While the Supreme Court declared the act unconstitutional in 1935, many of its labor and regulatory principles influenced subsequent legislation. The NIRA marked a transformative moment in federal intervention in the economy during the Great Depression.
