2nd millennium in the context of Alexander Graham Bell

1947 (MCMXLVII) was a common year starting on Wednesday of the Gregorian calendar, the 1947th year of the Common Era (CE) and Anno Domini (AD) designations, the 947th year of the 2nd millennium, the 47th year of the 20th century, and the 8th year of the 1940s decade.

It was the first year of the Cold War, which would last until 1991, ending with the dissolution of the Soviet Union.

The 11th century is the period from 1001 (represented by the Roman numerals MI) through 1100 (MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium.

In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy.

1908 (MCMVIII) was a leap year starting on Wednesday of the Gregorian calendar and a leap year starting on Tuesday of the Julian calendar, the 1908th year of the Common Era (CE) and Anno Domini (AD) designations, the 908th year of the 2nd millennium, the 8th year of the 20th century, and the 9th year of the 1900s decade.

As of the start of 1816, the Gregorian calendar was 12 days ahead of the Julian calendar, which remained in localized use until 1923.

This year was known as the Year Without a Summer, because of low temperatures in the Northern Hemisphere, possibly the result of the 1815 eruption of Mount Tambora in Indonesia, causing severe global cooling, catastrophic in some locations.

The 20th century began on 1 January 1901 (MCMI), and ended on 31 December 2000 (MM). It was the 10th and last century in the 2nd millennium and was marked by new models of scientific understanding, unprecedented scopes of warfare, new modes of communication that would operate at nearly instant speeds, and new forms of art and entertainment. Population growth was also unprecedented, as the century started with around 1.6 billion people, and ended with around 6.2 billion.

The 20th century was dominated by significant geopolitical events that reshaped the political and social structure of the globe: World War I, the Spanish flu pandemic, World War II and the Cold War. Unprecedented advances in science and technology defined the century, including the advent of nuclear weapons and nuclear power, space exploration, the shift from analog to digital computing and the continuing advancement of transportation, including powered flight and the automobile. The Earth's sixth mass extinction event, the Holocene extinction, continued, and human conservation efforts increased.

It was the final year of the Cold War, which had begun in 1947. Towards the end of the year, the Soviet Union collapsed, leaving fifteen sovereign republics and the CIS in its place. In July 1991, India abandoned its policies of dirigisme, license raj and autarky and began extensive liberalisation to its economy. This increased GDP but also increased income inequality over the next two decades. A UN-authorized coalition force from 34 nations fought against Iraq, which had invaded and annexed Kuwait in the previous year, 1990. The conflict would be called the Gulf War and would mark the beginning of a since-constant American military presence in the Middle East. The clash between Serbia and the other Yugoslav republics would lead into the beginning of the Yugoslav Wars, which ran through the rest of the decade.

1600 (MDC) was a century leap year starting on Saturday of the Gregorian calendar and a leap year starting on Tuesday of the Julian calendar, the 1600th year of the Common Era (CE) and Anno Domini (AD) designations, the 600th year of the 2nd millennium, the 100th and last year of the 16th century, and the 1st year of the 1600s decade.

The millennium celebrations were a worldwide, coordinated series of events to celebrate and commemorate the end of 1999 and the start of 2000 as well as the end of 2000 and the start of 2001 in the Gregorian calendar. The celebrations were held as marking the end of the 2nd millennium, the 20th century, and the 200th decade, and the start of the 3rd millennium, the 21st century, and the 201st decade (although the start and end points of such periods had been disputed). Countries around the globe held official festivities in the weeks and months leading up to the date, such as those organised in the United States by the White House Millennium Council, and most major cities produced firework displays at midnight. Equally, many private venues, cultural and religious centres held events. and a diverse range of memorabilia was created, including souvenir postage stamps.

As with every New Year's Eve, many events were timed with the stroke of midnight in the time zone of the location. There were also many events associated with the dawn on 1 January. An international television broadcast called 2000 Today was produced by a consortium of 60 broadcasters, while an alternative program Millennium Live was cancelled two days before the event.
