00:00The bottom line is that on this side of the Berlin Wall, Herr Krentz's government is lurching from crisis to crisis.
00:06On this side, Herr Kohl is facing massive problems too.
00:10Welcome to WatchMojo, and today we're taking a look at 10 moments in history after the year 1900 that had the greatest impact on humankind.
00:18What the Earth scientists are proposing is absolutely extraordinary.
00:22It's the most astonishing event, certainly in human history.
00:27The launch of Sputnik.
00:29A man-made celestial body for the first time in history overcame terrestrial gravity and flew into space.
00:36Less than half a century after the Wright brothers invented the airplane, humanity began sending objects into space.
00:43When the Soviet Union launched their Sputnik satellite into orbit, the eyes of the world were lifted upwards to the stars.
00:49Sputnik's technology was primitive.
00:52A rudimentary sphere with a simple radio transmitter that beeped.
00:57The space race began, as the US and Russia competed to develop newer and better spacefaring technology.
01:03More importantly, Sputnik was just the first of thousands of satellites sent into orbit.
01:08Global positioning, cell phones, television, and the internet are just a few of the ways satellites are integrated into the 21st century.
01:16Satellite surveillance and positioning are key parts of intelligence gathering and military campaigns.
01:22Accurate weather forecasting relies on satellite surveillance.
01:25Data from satellites are even used for crop management.
01:28Today, the global satellite industry is a $208 billion business.
01:34But that relatively small number belies how rapidly our dependence on satellite technology continues to expand.
01:41The Treaty of Versailles.
01:43The Great War started 1,797 days ago.
01:48In a few hours, it will be over.
01:51The Treaty of Versailles will be signed.
01:54The 20th century was the first that, from the very beginning, saw the rise of globalized international relations.
02:01The Treaty of Versailles ended World War I, utterly re-sculpting the world order.
02:06That single document would have profound impacts for the next hundred years.
02:10The treaty dismantled entire empires, redrawing borders in Europe and the Middle East.
02:15It imposed punitively harsh reparations on Germany, leading to decades of economic hardship and political instability.
02:22In their desperation, resentment turned to rage and bigotry as they sought comfort in the arms of autocracy under Adolf Hitler.
02:29On the 30th of January, 1933, Hitler became the head of the government.
02:36His aim, establish a pan-German racial state and abolish the unjust diktat.
02:43While intended to secure lasting peace, the treaty instead laid the groundwork for a second, more costly world war.
02:50The treaty's lasting legacy profoundly reshaped the global political landscape well into the 21st century.
02:56It would take another world war, another 40 million dead, for the world to start to learn how to make peace.
03:05September 11th attacks.
03:06The unthinkable happened today.
03:08The World Trade Center, both towers, gone.
03:11The September 11th attacks on the World Trade Center and Pentagon radically shifted geopolitics forever.
03:17In the wake of the end of the Cold War, the West had shifted into the complacency of a 90s boom.
03:22One renowned philosopher even called the era, quote, the end of history.
03:26Yeah, not so much.
03:28The U.S. and its allies soon invaded Afghanistan.
03:30By liberating Donna, we free the local populace from the influence of the Taliban.
03:36They're able to go about their daily lives.
03:37A smaller coalition followed up with another invasion into Iraq, and decades of conflict and turmoil ensued, and are still ongoing.
03:459-11 had so many repercussions on both individual lives and collective world history.
03:51The job of a president is to protect the American people from harm.
03:55And some presidents don't need to worry about that, and some do.
03:59And it turns out I was one that did.
04:01A possible Anthropocene.
04:02Many scientists claim we're now living in a new geological epoch.
04:08Because long after we're extinct, the scar of our existence will be visible in the sedimentary rocks that form the foundations of a new world.
04:17Scientists in the late 20th century first began to discuss the possibility that human activity was changing the Earth's geology and ecosystems in empirically measurable ways.
04:27They proposed that the scientific community universally adopt that the Earth has entered a new geological era.
04:33In 2024, the International Commission on Stratigraphy shot down the idea.
04:38Still, its discussion has helped scientists around the world recognize human impact.
04:50From altering atmospheric composition through greenhouse gas emissions, to widespread biodiversity loss, human actions have changed the planet in ways unprecedented in geological history.
05:01The Anthropocene's acknowledgement has also galvanized global efforts in environmental conservation, sustainability, and climate policy.
05:10The scale of what humans have done is sometimes so big, you have to freeze a moment in time to really see it and really understand it.
05:18The fall of the Berlin Wall
05:20Elsewhere, they were swarming over the wall, hacking at it with hammers, picks, and chisels, clawing at it with bare hands.
05:27In retrospect, the collapse of the Soviet Union was likely all but inevitable after the death of Leonid Brezhnev.
05:34Still, the fall of the Berlin Wall seven years later was the symbol of that collapse.
05:39It represented an end to Cold War divisions between East and West.
05:43For nearly three decades, the wall had stood as a physical and ideological barrier between communist East Berlin and capitalist West Berlin.
05:51It's demolition accelerated the inexorable dissolution of the Soviet Union and the collapse of communist regimes across Eastern Europe.
06:12In the wake of this change, a new world order was established, dominated by liberal democracies and free market economies.
06:20But later, authoritarianism from China and Russia also gained footholds in developing nations and economies.
06:27They were at the door shouting, the wall is open, we walk through the wall.
06:32The day the wall came down will be the most joyful day of my life.
06:36The Great Depression. In 1929, a stock market crash on Wall Street spread economic contagion around the world.
06:44Wherever you looked, boys and girls, men and women, were wondering what was ever going to happen to them.
06:52The Great Depression was a moment of great change for the world.
06:55Widespread economic suffering and hunger led people to rethink the role of government in their lives.
07:01I remember looking behind markets, the garbage cans, looking for like a head of lettuce.
07:10Some, like the U.S. with the New Deal, turned to a variety of governmental social welfare systems.
07:16Governments were acknowledged to have responsibility to create a social safety net.
07:21Other countries turned to the laws of totalitarianism and fascism.
07:25They used force and terror to rebuild their empires.
07:28This tension between authoritarianism and egalitarianism still defines geopolitics in the 21st century.
07:36COVID-19 outbreak.
07:38Cases are now accelerating rapidly.
07:42335 people have died from coronavirus. That's six times more than last week.
07:47In the fall of 2019, rumors began to bubble up in the U.S. and Europe about a new flu-like virus in China.
07:54No one could have predicted the global devastation that followed.
07:57By early 2020, COVID-19 had spread across the planet, leading to widespread lockdowns, crippled economies, and disrupted daily life.
08:06In a further effort to contain the spread of the virus, the government also increased testing capacity.
08:11Germany didn't want to make the same mistakes as France or Italy.
08:15Businesses closed, millions lost jobs, and supply chains faltered.
08:19Worse was the human suffering.
08:21The pandemic claimed over 1 million lives in the U.S. and at least 7 million globally, with some citing 15 million deaths.
08:29The psychological impact was also profound.
08:31Fear, isolation, and uncertainty took a heavy toll on mental health.
08:36The world was forever changed, as the virus reshaped how people work, connect, and view public health.
08:42Don't delude yourself into thinking only the old will die, or will get it.
08:47They're all ages.
08:48The invention of the Internet.
08:50The Internet, and the information age it sparked, has created a seismic shift that completely changed how we live and communicate.
08:58Human civilization is now in its second generation of the Internet age.
09:02Young people today may have difficulty fully understanding just how much the Internet has changed the planet.
09:08People in India can video chat in real time with someone in London.
09:13Students in South Africa can connect with counterparts in China on social media.
09:17The world is smaller and faster than it was 50 years ago.
09:21International business now happens at the speed of thought.
09:25Political movements have become global.
09:27Though it has become completely ubiquitous, few saw the Internet coming, and no one could have predicted its impact.
09:33Unfortunately, dangers have spread like wildfire, too.
09:36Misinformation, propaganda, and conspiracies can now circle the world before the truth wakes up in the morning.
09:43Love it, hate it, or both, there can be no doubt.
09:46The 21st century is the century of the Internet.
09:49All while connection speeds ramp up exponentially.
09:53The question now becomes, what could possibly be next?
09:57The Holocaust.
09:58Those who cannot remember the past are condemned to repeat it.
10:01I saw the word Auschwitz.
10:03The doors opened.
10:04Terror hit us immediately.
10:05In the modern era, where an estimated one in five young Americans don't believe the Holocaust happened, this statement still rings true.
10:13We've seen entertainers like Kanye West share anti-Semitic tropes.
10:17Even former President Trump had dinner with a prominent Holocaust denier.
10:21The Holocaust during World War II was Germany's monstrous, systematic, state-sponsored persecution and mass murder of millions of Jewish people, as well as other groups the Nazis targeted.
10:33Hitler ordered a rounding up of Jews, as well as other groups he hated, including gay people, Roma gypsies, and people with disabilities.
10:40It taught the world that turning a blind eye to human rights abuses has horrific consequences.
10:46The UN passed the Universal Declaration of Human Rights in 1948, after the war.

11:05Invention of the Assembly Line
11:10The Assembly Line was arguably first invented in 1901, but most famously implemented by Henry Ford in 1913.
11:28It sparked a global revolution in manufacturing by streamlining production processes.
11:33This drastically reduced both the time and cost of making goods.
11:38By the middle of the 20th century, the assembly line was the cornerstone of the efficient mass production of standardized products.
11:44Prices plummeted, allowing a wider pool of consumers to access goods.
11:49In 1910, Ford opened the 60-acre Highland Park plant and set up the machinery on the shop floor in the actual sequence of automobile production.
11:57It reshaped labor practices, creating specialized roles and repetitive tasks.
12:03The assembly line played a crucial role in creating a global marketplace, enabling economies of scale.
12:09This shift in production laid the foundation for modern consumer culture.
12:13Today, virtually every consumer product, from cars to electronics, was likely created on an assembly line.
12:20It saved enormous amounts of wasted motions and it brought an enormous reduction in the cost of making Model T.
12:28What part of history are you most interested in?
12:31Let us know in the comments.
12:32If you can make something as complicated as an automobile on an assembly line, the reasoning goes that I ought to be able to make toasters and phonographs and other things, which should be much simpler.
