The three events I consider the most important in American history are the pneumocystis pneumonia report in 1981, which states the discovery of the virus known as “Pneumocystis carinii” as the cause of the AIDS epidemic. The discovery of AIDS brought more attention to sex education and insight is gay unions as a major cause of the spread of the virus. AIDS and gay unions are still hot topics of discussion to date. The second event is the signing of the Americans with disabilities act in 1990 which formed the basis of equality and inclusivity of persons with disabilities in society. today. The act changed most individuals’ attitudes towards persons with disabilities bringing acceptance and equality regardless of the physical and psychological differences. Finally, the third event is the Republicans’ victorious win to congress in 1994 after being in the opposition since 1954. The Republicans’ victory marks the beginning of America’s legislative power creating a more conservative than a liberal administrative system. These three events have shaped most of America’s significant areas of society throughout history.
