The 20th (twentieth) century was a century that began on January 1, 1901 and ended on December 31, 2000. It was the tenth and final century of the 2nd millennium. It is distinct from the century known as the 1900s which began on January 1, 1900 and ended on December 31, 1999. The 20th century was dominated by a chain of events that heralded significant changes in world history as to redefine the era: flu pandemic, World War I and World War II, nuclear power and space exploration, nationalism and decolonization, the Cold War and post-Cold War conflicts; intergovernmental organizations and cultural homogenization through developments in emerging transportation and communications technology; poverty reduction and world population growth, awareness of environmental degradation, ecological extinction; and the birth of the Digital Revolution. It saw great advances in communication and medical technology that by the late 1980s allowed for near-instantaneous worldwide computer communication and genetic modification of life. Global total fertility rates, sea level rise and ecological collapses increased; the resulting competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others; consequences which are now being dealt with. It took over two-hundred thousand years of human history up to 1804 for the world's population to reach 1 billion; world population reached an estimated 2 billion in 1927; by late 1999, the global population reached 6 billion. Global literacy averaged 80%; global lifespan-averages exceeded 40+ years for the first time in history, with over half achieving 70+ years (three decades longer than it was a century ago).
The 20th century was the period between January 1, 1901 and December 31, 2000, inclusive. The century had the first global-scale wars between several world powers across multiple continents in World War I and World War II. Nationalism became a major political issue in the world in the 20th century that was acknowledged in international law with the acknowledgement of the right of nations to self-determination, official decolonization in the mid-century, and many nationalist-influenced armed conflicts - including both World Wars. Feminism that demanded that women have equal rights to men, was a major political issue in the world, and particularly in the result of granting women suffrage in many countries. The century saw a major shift in the way that vast numbers of people lived, as a result of changes in politics, ideology, economics, society, culture, science, technology, and medicine. It has been theorized that the 20th Century saw more technological and scientific progress than all the other centuries combined since the dawn of civilization. Terms like ideology, world war, genocide, and nuclear war entered common usage. Scientific discoveries, such as the theory of relativity and quantum physics, drastically changed the worldview of scientists, causing them to realize that the universe was fantastically more complex than previously believed, and dashing the strong hopes at the end of the 19th century that the last few details of scientific knowledge were about to be filled in. Accelerating scientific understanding, more efficient communications, and faster transportation transformed the world in those hundred years more rapidly and widely than in any previous century. It was a century that started with horses, simple automobiles, and freighters but ended with high-speed rail, cruise ships, global commercial air travel and the space shuttle. Horses, Western society's basic form of personal transportation for thousands of years, were replaced by automobiles and buses within the span of a few decades. These developments were made possible by the large-scale exploitation of fossil fuel resources, which offered large amounts of energy in an easily portable form, but also caused widespread concerns about pollution and long-term impact on the environment. Humans explored outer space for the first time, taking their first footsteps on the Moon.
