Transcript of Chronology:20th Century Timeline

Timeline of the "Most Important Events of the 20th Century." 1904-Teddy Roosevelt becomes the 26th president and promises the American people a "Square Deal," that had 3 parts: Conservation of Natural Resources, Control of Corporations, and Consumer Protection. This is important because it helps the American middle class feel they would be treated fairly and that big businesses and trusts who were bad would be dealt with. December 17, 1903 Orville and Wilbur Wright made the first successful airplane. It carried a man, and rose into the air by its own power, traveled at even speed, and descended without damage. This is important because it allowed the rate of technological advancement to increase at an extremely high rate April 6, 1917- US declared
war on the Central Powers
(Germany, Austria-Hungary,
and Turkey) and gets involved
in World War I joining the
Allied Powers (Britain and
France.) The sinking of the Lusitania,
the Zimmerman telegram, and
propaganda were some of the
reasons the US declared war. This is important because it marks our involvement in a World conflict, and will lead to many casualties and deaths. It will also change our foreign policy from one of Neutrality which George Washington suggested in his Farewell Address. September 28, 1928- Penicillin was discovered by Alexander Flemming, and it was used to fight of deadly bacterial infections. Using antibiotics one could kill bacteria that previously was fatal Once devastating bacterial diseases could now be fought off with the new advent of antibiotics, this realization of using fungal drugs was a mishap, but it helped the medical fields today, plus it is the basis of many other complex antibiotics. October 29, 1929- On Black Tuesday
the stock market crashes. Over 16.4 million
shares of stock were sold in one day and because people had bought them on margin- they couldn't afford to pay the original cost of the stock. No one was buying any of the stocks being sold- and panic struck the country. The market was closed by the afternoon This is important because it marks the beginning of a national economic crisis called the Great Depression which lasts until World War II. People could not find jobs, pay bills, feed their families, and the country was devastated 1933 to 1936-Congress passes the first 15 programs of the New Deal which were proposed by F.D.R.-3 ideas- relief- help the poor, recovery- bring the country out of the depression and reform-prevent this from ever happening again. This was important because the President was attempting to guide the county through the Depression, and prevent it from occurring again while being criticized for being over involved in the economy and people's lives. Some of the programs he passed were considered unconstitutional while others like Social Security are still around today. August 2, 1939- Just before World War II a letter was written to FDR addressed from Peconic, Long Island from Albert Einstein, telling him in efforts of Nazi Germany, to purify Uranium-235, which created the atomic bomb, and started the "Manhattan Project." This event forever changed the way world power is distributed throughout the planet. It has also given humans an excuse to become more dangerous and ruthless to each other. December 7, 1941- The Japanese attacked Pearl Harbor, Hawaii. 2,403 people died, and the next day the United States joined the grueling WWII This event changed the US from an isolationist nation to the world's "policeman" for good, and bad but overall this got the US involved in a lot of foreign affairs. This War ends the Great Depression later on. August 6, 1945 (Hiroshima)
August 9, 1945 (Nagasaki)-
The United States drops atomic bombs on Hiroshima and Nagasaki in Japan during World War II. The first bomb was called the "Little Boy" and the second "Fat Boy". It was ordered by President Harry S. Truman and dropped by the Enola Gay. The bombing resulted in 90,000-160,000 dead in Hiroshima, and 60,000-80,000 in Nagasaki. This was important because it led to Japan's surrender six days later. It is also the only nuclear active bombings to the date in the act of war. The surrender of Japan officially brought the Second World War to an end. This was important because it led to the civil rights movement and was a court case ruling for equal rights and against discrimination. This case could be used to help win other cases where people were discriminated against, treated unfairly, and to end segregation and fight Jim Crow Laws in the South. May 17, 1954- Brown vs. Board of Education requires the integration of schools. Determined that the original Plessy v. Ferguson court case saying "separate but equal" is not okay. It said segregation violated the 14th amendment. Thirteen parents sued the school district on behalf of their children because their segregated schools were farther away and not as good as the "white"schools in their neighborhoods. 1961- American military advisors are sent to Vietnam. A special group called Echo 31 was sent to help train members of South Vietnam Army. President Johnson backed this mission. This starts the US involvement in the Vietnam War. This is important because it marks the beginning of the US involvement of one of the longest and most unpopular wars in American History. It resulted in the War Powers Act of 1973 making it necessary for the President to get approval from Congress before sending military forces overseas. February 1964- The Beatles made several consecutive Sunday appearances on the Ed Sullivan show, and "I Want to Hold Your Hand," had risen to No.1 on the charts. The Beatles' first broadcast had created an all time television record of 73million viewers. Beatlemania had struck the nation, and as the radio waves were saturated with their music, there was no stopping the fan craze. John Lennon, Ringo Starr, Paul McCartney, and George Harrison had become a United States pop legend icon. This event is important because their first appearance on February 9 is considered a milestone in American pop culture and the beginning of the British Invasion in music. The Beatles took off and became music sensations, but also brought the rest of the music industry with them. The Beatles spoke to the nation and got a huge response because of it. July 16, 1969- NASA had blasted off the Apollo 11 into space with Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins as the astronauts. They had a mission, which was to set foot on the moon.
July 20 1969- Neil Armstrong became the first human to step on the moon. He and Aldrin walked around for three hours. They did experiments. They picked up bits of moon dirt and rocks. They set up the US flag, and left a sign on the moon. July 24, 1969- all three astronauts came back to Earth safely. These events are important because they changed technology, and increased the world's knowledge of powerful forces, and made space travel, and astronomy a new interest of the public. Also, President Kennedy's wish came true. It took less than 10 years. Humans had walked on the moon. July 27, 1974- The Watergate Scandal comes to a head when the House of Representatives accuses President Richard Nixon of directing agents to take political evidence from an office building, covering it up, and the lying about his involvement and knowledge of it. He resigns from office on August 9, 1974 before he is officially removed. This is important because the President of the United States is officially investigated and brought up on charges of wrongdoing. He is the only president to have resigned his position. This shakes American citizens' beliefs in the political system of the United States. Apple Inc was established on April 1, 1976 in Cupertino, California, by Steve Jobs, Steve Wozniak, and Ronald Wayne, and was incorporated January 3, 1977,
Apple Computers went on sale for the first time, and a personal computer was sold. A multinational and a multi-billion dollar company was born. Apple's establishment has changed technology infinitively, because it created so many new opportunites and inventions for not only America, but the world. The discovery of AIDS shaped the medical field today, and proved what humans are capable of finding out about diseases. This also scared the nation and showed how powerful some forces are, and you must be cautious and smart when decision making. June 5,1981-A medical phenomenon breaks through where the first recorded case of the soon to be discovered new retro virus, AIDS is found in Los Angeles. The other first recognized cases of AIDS occurred in the USA in the early 1980s Thousands of people all over the world, especially in New York and California suddenly began to develop rare opportunistic infections and cancers that seemed stubbornly resistant to any treatment. Signed on December 8, 1987. Ratified on May 27, 1987- In the spirit of glasnost and dentene, Ronald Reagan and Mikhail Gorbachev sign the Intermediate Nuclear Force Treaty (INF). Signed in Washington D.C. the INF eliminated ground launched cruise missiles with intermediate ranges. It also allowed both countries to inspect each others weapons installations. This was important because it led to the destruction of deadly weapons, built trust between the United States and Soviet Union and helped lead to the end of the Cold War. This was important because it led to a heightened fear in the US about terrorism and proved that the US was not invincible to attacks. February 26, 1993- The first World Trade Center bombing, A truck bomb went off in the parking garage around 12pm under the North Tower. Four men were convicted belonging to the AlQaeda terrorist group. Six people were killed and over 1000 were wounded in the attack. 1914-Ford began paying his employees five dollars a day, nearly doubling the wages offered by other manufacturers. He cut the workday from nine to eight hours in order to convert the factory to a three-shift workday. Ford's mass-production techniques would eventually allow for the manufacture of a Model T every 24 seconds. His innovations made him an international celebrity.It not only improved transportation (obviously), it also gave the economy the boost it needed to provide America with the age of prosperity that the 20s is known for. Henry Ford had created the assembly line, which made luxuries more affordable to Americans. This invention had contributed to the roaring twenties, but it also contributed to the Great Depression. This event is important because it shows how far America has come with equal rights for men and women. Women were now allowed to combat in war, which expanded the military, and because of that, made the US a stronger nation. In September 1977, men and women began training in the same basic training units at Fort McClellan and Fort Jackson and in October 1978 at Fort Dix and Fort Leonard Wood.

Enlistment qualifications became the same for men and women by order of the Secretary of the Army on Oct. 1, 1979.

An act of Congress passed in October 1975 directing the Academy to accept women into its training program in 1976. The first women cadets graduated form the United States Military Academy, West Point, N.Y., in 1980. Since then, women have continued to enter every class at the United States Military Academy.

THE 60's are the
DECADE: The most influential, and provocative decade of the 20th century was with out a doubt, the sixties. There were numerous political milestones that not only affected the nation for the time being, but they had impacted the lives of Americans infinitely. The Civil Rights Movement was materializing, and leaders of this movement, like Martin Luther King Jr., took action in his, "I Have a Dream," speech, and Rosa Parks as she was jailed for defying the Jim Crow Laws, and others such as John F Kennedy were fighting against segregation, and supporting the Civil Rights Movement. This movement had long term positive effects by creating equal rights for all Americans. Along with these controversial issues, the music industry skyrocketed, creating both American, and international music icons. Artists like, The Beatles, Elvis Presley, Jimmy Hendrix, Janis Joplin, and The Jackson 5 swept the nation with their catchy tunes, and with these they stole the nation's heart's. Some of these legends debuted on programs like, The Ed Sullivan Show, while others channeled an inner feeling of peace at the Woodstock Music Festival. The music industry inspired numerous people, as many genres such as rock, soul, and pop struck the country. Along with these uplifting events, also came tragedies, that had left the United States devastated. President John F Kennedy due to his efforts and encouragement of abolishing segregation, was assassinated by Lee Harvey Oswald; Martin Luther King Jr. was assassinated by James Earl Ray in attempts for equal rights, while Robert F Kennedy was assassinated by Sirhan B. Sirhan. These catastrophic events deeply saddened every household in the country, and its great significance had impacted Americans. The 60'were overall very instrumental in shaping the nation, and where America stands today.
