5 Things in History that Changed the World

In this episode of Untold History Revealed, we explore five world-changing historical events that still shape modern life today—from the global impact of the Crimean War to how the Spanish Flu pandemic increased long-term medical costs to the surprising story of Commodore Matthew Perry’s flag at the Japanese surrender in World War II. We also uncover how the sinking of the Titanic influenced the development of car radios and how the World Bank was established in New Hampshire at the Bretton Woods Conference. These pivotal moments in world history may seem unrelated, but each triggered monumental changes that continue to affect our economy, healthcare system, technology, and global power structure.

The result was a fun podcast to put together. We did discuss several topics; however, they all had the common relationship of how the events affected the world that we know today. So sit back and enjoy.

The Crimean War

The **Crimean War** reshaped global politics by weakening the Russian Empire and disrupting the long-standing balance of power in Europe. Fought primarily between Russia and an alliance of the Ottoman Empire, Britain, France, and Sardinia, the war exposed Russia’s military and logistical weaknesses. Its defeat forced Russia into a period of internal reform under Tsar Alexander II, including the emancipation of the serfs in 1861. Meanwhile, the conflict strengthened diplomatic ties between Britain and France and elevated the Kingdom of Sardinia, which used its participation to gain favor with European powers—helping pave the way for Italian unification.

The war also transformed modern warfare and journalism. It is often considered one of the first “modern” wars due to the use of railways, telegraphs, steam-powered ships, and modern rifles. For the first time, war correspondents sent reports directly from the battlefield, bringing graphic accounts of suffering into the homes of civilians. The work of figures like **Florence Nightingale** revolutionized nursing and battlefield medical care, leading to major reforms in sanitation and hospital organization. Public outrage over mismanagement and poor conditions pressured governments to become more accountable to their citizens.

Globally, the Crimean War accelerated the slow decline of the Ottoman Empire while intensifying rivalries that would shape future conflicts. The weakening of Ottoman control in southeastern Europe fueled nationalist movements in the Balkans, contributing to decades of instability that eventually helped spark **World War I**. It also shifted diplomatic alliances, ending the so-called “Concert of Europe” cooperation that had kept relative peace since the Napoleonic Wars. In many ways, the Crimean War marked the beginning of a more volatile, modern era of international politics that extended far beyond the battlefields of the Black Sea.

Titanic and how it affected car radios

The sinking of the **RMS Titanic** in April 1912 dramatically changed wireless communication laws—and those changes eventually shaped how radio developed in everyday life, including in our cars. When Titanic struck an iceberg, its wireless operators sent distress signals that were picked up by nearby ships. However, investigations revealed serious communication failures: some ships did not maintain 24-hour radio watches, and commercial messages sometimes took priority over safety traffic. In response, governments passed sweeping reforms, most notably the **Radio Act of 1912**, which required continuous monitoring of distress frequencies and stricter licensing of radio operators and stations. This law marked the beginning of strong federal oversight of the airwaves.

Those reforms laid the foundation for organized broadcasting. Once governments began regulating radio frequencies, the chaotic early wireless environment became structured and reliable. Over the next decade, experimental wireless communication evolved into public broadcasting, with licensed stations transmitting news, music, and entertainment to mass audiences. This regulatory framework later expanded under the **Communications Act of 1934**, which created the Federal Communications Commission and solidified how radio frequencies were assigned and protected from interference. Without the Titanic disaster pushing governments to regulate and standardize radio operations, the orderly broadcast system that made commercial radio practical might have developed much more slowly.

By the 1920s and 1930s, as automobile ownership surged, manufacturers began installing radio receivers in cars. Because the airwaves were now licensed, coordinated, and relatively free of signal chaos, drivers could tune in to clear, consistent broadcasts while traveling long distances. In that indirect but powerful way, the Titanic tragedy helped transform wireless telegraphy from a loosely organized maritime tool into a regulated mass-communication system—one that ultimately made it possible for us to turn a dial in our cars and reliably hear music, news, and emergency alerts on the road today.

Spanish Flu and Medical Costs

The **Spanish flu** placed sudden and enormous financial strain on health systems around the world. Hospitals were overwhelmed, temporary wards were set up in schools and public buildings, and cities had to hire emergency staff to care for the sick. Because antibiotics did not yet exist and vaccines were unavailable, treatment focused on supportive care—nursing, quarantine enforcement, and sanitation—all of which required manpower and supplies. The sheer scale of illness increased public and private spending on medical services, revealing how unprepared most nations were for a global health crisis.

In the years that followed, the pandemic reshaped how governments thought about public health funding. Many countries expanded investments in health departments, disease surveillance, and laboratory research to prevent a repeat catastrophe. The crisis helped strengthen arguments for national health insurance programs and employer-based medical coverage, especially as families struggled to afford care during widespread economic disruption. In the United States, for example, the experience of 1918 influenced later public health infrastructure growth and, over time, contributed to policy debates that eventually shaped large-scale reforms such as Social Security–era health initiatives and mid-20th-century hospital expansion programs.

The long-term financial legacy of the pandemic also influenced modern medical cost structures. The Spanish flu highlighted the economic consequences of infectious disease outbreaks—not just hospital bills, but lost wages and productivity. This realization encouraged the development of more organized health systems, expanded medical training, and eventually the pharmaceutical industry’s growth. While it did not immediately create modern insurance systems, the pandemic exposed the true cost of inadequate healthcare infrastructure, helping drive the expansion and professionalization of medical services that, over the 20th century, increased both the availability—and the overall cost—of medical care worldwide.

Commodore Matthew Perry and the Atomic Age

Commodore **Matthew C. Perry** is indirectly connected to the Atomic Age because his 1853–1854 expedition to Japan fundamentally reshaped U.S.–Japan relations. When Perry’s “Black Ships” forced the Tokugawa shogunate to open Japanese ports through the Convention of Kanagawa, it ended more than two centuries of relative isolation. That encounter exposed Japan to Western industrial power and accelerated the political transformation that followed in the Meiji Restoration. In many ways, Perry’s arrival marked the beginning of Japan’s rapid modernization, which would eventually turn it into a major industrial and military power.

Over the next several decades, Japan adopted Western military technology, industrial systems, and centralized governance. By the early 20th century, it had become an imperial power, defeating Russia in 1905 and expanding aggressively in East Asia. This rise ultimately brought Japan into direct conflict with the United States during **World War II**, especially after the attack on Pearl Harbor in 1941. The war in the Pacific escalated into one of the most brutal theaters of the conflict, culminating in the United States’ decision to deploy atomic weapons against Japan in 1945.

Those atomic bombings—most notably on **Hiroshima** and Nagasaki—ushered in the Atomic Age, transforming global warfare, diplomacy, and science. While Perry himself lived nearly a century earlier, his actions initiated a chain of geopolitical developments that reshaped Japan’s trajectory and, indirectly, the course of global history. By opening Japan to Western influence and industrialization, Perry helped set in motion the modernization that eventually positioned Japan as a central player in the events leading to the dawn of nuclear warfare and the Atomic Age.

When Japan officially surrendered aboard the battleship **USS Missouri** on September 2, 1945, the U.S. Navy deliberately displayed Perry’s historic 1853–1854 flag. The flag had been flown from Perry’s flagship during his expedition to open Japan to Western trade. Its presence at the signing ceremony was symbolic—representing the beginning and the end of a dramatic chapter in U.S.–Japan relations.

The surrender ceremony formally ended **World War II** in the Pacific and marked the dawn of the Atomic Age. By displaying Perry’s flag, the United States underscored the historical arc from the forced opening of Japan in the 19th century to Japan’s surrender in 1945. It was a powerful visual reminder that the relationship between the two nations—first shaped by Perry’s “Black Ships”—had come full circle.

The World Bank Begins in New Hampshire

The origins of the World Bank trace back to July 1944, when representatives from 44 Allied nations gathered in Bretton Woods, New Hampshire, during the final year of World War II. The meeting, formally known as the Bretton Woods Conference, was held at the elegant Mount Washington Hotel. With much of Europe and Asia devastated by war, leaders recognized the urgent need for a stable international financial system that could prevent another global economic collapse like the Great Depression and help rebuild shattered economies.

Out of that conference came two major institutions: the International Monetary Fund and what was originally called the International Bank for Reconstruction and Development, now known as the World Bank. While the International Monetary Fund was designed to stabilize currencies and oversee exchange rates, the World Bank’s primary mission was to provide long-term loans for reconstruction and development. Its initial focus was rebuilding war-torn Europe, but over time its mission expanded to funding infrastructure, poverty reduction, and development projects in nations around the globe.

The decision to create the World Bank in a quiet New England resort town reflected the urgency and forward-thinking vision of Allied planners. They understood that economic instability had contributed to global conflict, and they sought to build a framework that would encourage cooperation rather than competition. From that summer meeting in New Hampshire emerged a cornerstone of the modern global financial system—an institution that continues to shape development policy, international lending, and economic recovery efforts around the world.
