From 1999 through 2007, we were in World Cycle 223 – a 7 cycle. 7 cycles are known for cultural advancement, religious events, and treaties. The 2s indicate that both cooperation and conflict were likely. The 3 pretty much guaranteed that there would be some form of cultural advancement.
The events of this period are recent enough that few world history books cover them. It was long enough ago that my own memories are a bit hazy. Thus, I will cover only events that the United States was a major part of during this time. If you have access to information on other events, then go ahead and discover for yourself how those events fit into culture, religion, and treaties (trade deals count here, since they are a form of treaty between two or more countries).
The seminal event of this period is, of course, the attacks of September 11, 2001. This was a universal 3 year, 3 month, and 5 day. The 3s are indicative of culture, but the 5 indicates change. Therefore, we had a change in our cultural mindset on that day. The attacks were carried out by a particularly militant cult that associated itself with Islam. (Please note that most Muslims do not have any wish to be associated with any such cult, just as most Christians do not wish to be associated with any of the more extreme cults in the U.S., though many of those cults associate themselves with Christianity.) Thus, we have both a religious event and conflict. Many changes to the American cultural mindset date back to that event. For example, many news programs started to place more emphasis on events that threaten the safety or security of small groups of people, which in turn led to more parents trying to keep their children as safe as possible – thus, the ‘helicopter parent’ phenomenon.
This event also led the war in Afghanistan, then the war in Iraq. Both of these wars were unusual in how they started. Typically, one nation will declare war on another nation, and then both sides will scramble to find allies as the war tilts in one nation’s favor or another. With these ‘wars’ (though technically they are only considered conflicts), the United States chose to obtain the blessings and cooperation of the member nations of the United Nations. Many of those nations chose to join forces. Rather than shortening either conflict, such cooperation actually protracted both conflicts, as agreements had to be drawn up about who would exit each country when, and how the retreating forces would be protected by those still there. As the adage goes, there were too many cooks in the kitchen.
This is the period in which smartphones and tablet computers started to become ubiquitous. Use of the Internet also skyrocketed. As we numerologists know, the number 7, when applied to the individual, is associated with science and technology (among other things). So it is not a surprise that these technologies were embraced by cultures around the world, or that such technologies in turn wrought cultural change.
If you wish to compare 1999-2007 to previous 7 cycles, the three previous cycles are 1918-1926, 1837-1845, and 1756-1764.
