The rule of the Bavand dynasty in Mazandaran is brought to an end by the murder of Hasan II.
On April 17, 1349, the Bavand dynasty's long rule over Mazandaran in northern Iran ended abruptly when its last ruler, Hasan II, was assassinated. This event brought an end to a dynasty that had governed the region for over four centuries.
The Bavand dynasty had ruled Mazandaran since the early medieval period, navigating challenges from neighboring powers and internal factions. Hasan II's murder on April 17, 1349, was orchestrated by disgruntled nobles within his court. His death triggered a power vacuum that allowed rival dynasties to assert control. The fall of the Bavands marked a significant shift in the political landscape of northern Iran. Local traditions and historical records preserve the memory of the dynasty's patronage of art and culture. The end of their rule also paved the way for the rise of the Marashis and later dynasties in Mazandaran.

Spain and Christopher Columbus sign the Capitulations of Santa Fe for his voyage to Asia to acquire spices.
On April 17, 1492, the Catholic Monarchs of Spain and explorer Christopher Columbus signed the Capitulations of Santa Fe. This historic agreement granted Columbus titles and privileges for his planned voyage to find a westward route to Asia.
The Capitulations of Santa Fe were finalized after months of negotiations between Columbus and King Ferdinand II and Queen Isabella I. Under its terms, Columbus was named Admiral of the Ocean Sea and given the titles of viceroy and governor over any lands he might discover. He was also promised a share of the wealth and a portion of the proceeds from the expedition. The agreement reflected Spain's ambition to compete with Portugal in overseas exploration and the lucrative spice trade. Columbus set sail later in 1492, leading to the European discovery of the Americas. The capitulations laid the legal foundation for Spain's claims in the New World and the subsequent era of Spanish colonization.

The Supreme Court of the United States decides Lochner v. New York, which holds that the "right to free contract" is implicit in the due process clause of the Fourteenth Amendment to the United States Constitution.
In Lochner v. New York, the U.S. Supreme Court enshrines a broad right to free contract under the Fourteenth Amendment.
Lochner v. New York was decided on April 17, 1905, when the U.S. Supreme Court struck down a New York law limiting bakers' working hours. Justice Rufus Peckham authored the majority opinion, arguing that the 'right to free contract' was protected by the due process clause of the Fourteenth Amendment. The decision became a hallmark of the Lochner era, emphasizing judicial review of economic regulations. Critics decried the ruling for prioritizing individual liberty over public welfare. The case influenced constitutional debates for decades until it was effectively overturned during the New Deal era. Lochner remains a focal point in discussions of substantive due process and judicial activism.

The Communist Party of Korea is established in colonial Korea by Kim Yong-bom and Pak Hon-yong under Japanese rule.
On April 17, 1925, the Communist Party of Korea was founded in Keijō (now Seoul) during Japan's colonial rule over Korea. Led by Kim Yong-bom, a veteran activist, and Pak Hon-yong, the party sought to unite workers and peasants against imperial exploitation.

Although the party faced immediate crackdown and arrests, it laid the groundwork for a lasting communist movement in Korea. Its legacy influenced both North and South Korean political developments after World War II. The CPK's founding marks a key moment in Korean resistance to colonialism and the spread of international ideologies.

Historian Tran Trong Kim becomes Prime Minister of the Empire of Vietnam under Japanese occupation in 1945.
On April 17, 1945, Tran Trong Kim, a respected historian and academic, was appointed Prime Minister of the newly formed Empire of Vietnam. His government was established under the auspices of Imperial Japan during its brief promotion of Vietnamese autonomy. Kim sought to navigate the complex political landscape as Japan’s influence waned amid World War II’s final months. He aimed to assert Vietnamese interests while managing Japanese demands and emerging domestic factions. Despite his intellectual stature, Kim’s administration faced challenges from growing nationalist and communist groups. His tenure was marked by efforts to modernize the government’s institutions and promote educational reforms. However, the end of Japanese occupation in August 1945 led to the empire’s collapse. Tran Trong Kim’s short-lived premiership remains a notable episode in Vietnam’s path to independence.

The last French troops are withdrawn from Syria.
France completes its military withdrawal from Syria, ending its mandate over the country in 1946.
On April 17, 1946, France formally withdrew its final military forces from Syria, ending a mandate that had lasted since the end of World War I. The evacuation marked the recognition of Syrian sovereignty after years of nationalist agitation and diplomatic pressure. French troops had occupied major cities and strategic sites throughout the mandate period. The withdrawal followed the signing of a Franco-Syrian treaty earlier that year, agreeing to Syrian independence. Upon departure, Syrian leaders celebrated the end of colonial rule and convened their provisional government. The event paved the way for Syria’s entry into the United Nations later that year. It also signified the broader decline of European colonial empires in the post-war era. The end of the French mandate reshaped Syria’s political landscape and regional dynamics in the Middle East.
